FV tire discussion

[Steve Davis]

Danny,
I THOUGHT that was what I was saying ... guess I'm not too good at wording things .. sorry. The FOCUS was on SINGLE CLASS RACING from NEFV.. CCS just added the Radials to it... and moved away from SCCA (mostly) to achieve that same goal (SCR). I have obviously been on the OUTSIDE of both groups, but following closely and in favor of both (same SCR) goals. More VEEs on track in their OWN group/sessions.

As information - a picture of the Yokohama radial mounted to a very beautiful cast aluminum wheel that looks like an original VW slot -




Just received a set today.

What is the actual tire size? When I zoom in, it pixilates too much.

Glenn, as Harry responded the info is at that link...
The tires are Yokohama Advan A052, 195/50R15. There are multiple wheels now allowed. I chose the Mobelwagen that looks like the original VW slots. They are the required 5.5 inch width and correct backspacing. The picture doesn't do it justice IMO as it is quite nice looking. There are multiple brands of these on the market and I believe they are all from the same chinese factory. As I discovered a year ago when buying wheels for my Jeep, almost all cast wheels are made in China, including some that obscure their manufacturing location.
Regards,
Barry

[DannyPip]

Barry, those black Mobelwagen wheels look GOOD!!!

Where did you get them? I know that Tire Rack is now a distributor. You can get them mounted and balanced and shipped easy peasy. Then you need longer lug bolts or studs and nuts.

Just so guys know, Mobelwagen Interceptor(what Barry has above) 5 x 205 wheels use ball seat lug nuts/bolts.

The Cip1.com wheels use 60 degree taper or acorn seat nuts/bolts.

Make sure you don't mix and match.

Longer bolts or studs are DEFINITELY needed no matter WHICH aluminum wheel you use, the flanges are WAY thicker than steel.

"Ball seat" not true. I had same concerns but finally determined that the CURRENT VERSION of the Mobelwagen 520 series wheels are actually 60 dgree ACORN attachment hardware. I'm sure that Barry would agree.

Steve, fv80

MMMM yeah, OK.

Check the manufacturer's website. They "might" know what they're talking about.

https://mobelwagen.com/products/520b...SABEgK1E_D_BwE

It's even highlighted in RED.

If that's not the case, somebody should tell them to change their website. The ones I have seen made by Mobelwagen over the past few years have used VW group ball seats.

[BLS]

Danny, I got mine through the local Discount Tire store after looking up the Mobelwagen distributor list. Unfortunately they could not balance them as they don't have the adapter for the spin balance machine. But they mounted them of course, and Yokohama has a dot on the tire that they say should line up with the valve stem location and apparently that helps the balance (no idea why).

They are ball seat on mine. I suspect that Steve's source are the cone type. I'm guessing they are made in the same factory both ways and Steve's are cone. The CIP1 version is a cone and from the pictures it sure looks like the same wheel.

And yes, the flange is pretty thick. They really do look nice.

[BLS]

By the way, those wheels are also available as 4.5 inch width and would beat the replacement steel wheels all to heck and back looks wise.
I think the lighter steel wheels are near the same as these cast aluminum so it would be nice if the SCCA would allow them for the slick tires...

[BLS]

Just looking, Empi has a set of studs that are 5mm (3/16") longer than the standard stud. Empi part # 70-2877-0 . Lowest price I found was J-Bugs at $10.95 per set of 5.

[DannyPip]

These rims all MAY be from the same factory, but I don't think so.

I have had Vintage 190 wheels on my 550 Spyder since 2017. The guy I bought them from (Greg at Vintage Motorcars Inc.) told me that his wheels are really Mobelwagen but re-boxed and without the logo on the wheel.

I also have the 3-fifty-6 wheels from Cip1.com on my Vee. They are NOT from the same factory, if you look at them side by side. But I could be wrong.

By the way, the 550 has 4.5" on the front and 5.5" on the back. Tires are Vredestein Sportrac5(NLA) in 185/65HR15 and 195/60HR15 respevtively. They are 300 treadwear and quite sticky for the street.

[BLS]

I started a new thread related to the tires and wheels in order to stop robbing the original

https://www.apexspeed.com/forums/sho...464#post672464

[Lucien j LeBlanc]

I would also add (in support of Rich's post) that the original goal of the NEFV group was SINGLE CLASS group/racing. CCS took that another step and made it 'more' affordable as well as SINGLE CLASS racing by adding in a spec street radial. The Radial tire savings AND the Single Class racing aspects are THE ITEMS that got this radial thing going and made it fully successful. Brian's questions of 'how do you KNOW the radials are what made it what it is .. successful.. Well.. we don't KNOW for sure which carried the most weight, but NO ONE can argue with the success of the whole program. For MY money, Single Class racing out weighs the radial cost savings, but the RISKS of racing in multi class groups (for me) vastly outweighs any other aspect. The risks of racing in groups with other race cars that are 30+ MPS faster on the straights is just more risk than I'm interested in taking. I would support the inclusion of FST as well as long as they are scored separately. but that's another discussion for another time.
Steve, FV80

On the west coast our race groups in FST and FV have diminished greatly. To race you have to contend with multi class groups where many cars are much faster on the straights and even have wings. This is one of the reasons (there are many) why I stopped running FV after many years of doing so and going to FST because we were initially grouped with Spec Racer Fords. Now with the lack of FST participation I went to FS changing my FST to having a bigger motor and taller 3.88 R&P gear box so that I could better survive out there on the track. The car now can stay with Club Fords on the straights, and I have a "dual class capable car". I am not advocating that others go to FS as I have but you should allow FST to run with the FV groups to have what is essentially similar reasonable speeds to get away from the multi class race groups which have killed our racing on the west coast. I remember 25 car fields at Willow Springs CA when I started racing SCCA with my FV. Mixing us in with Formula Fords and f440 's helped killed us off.

Assuming the correct lug nut shape/angle, is there much galling of the wheel lug nut seats when using steel lug nuts?

I found some beautiful titanium lug nuts with a floating seat/mating surface. While this would eliminate seat galling, you would then be facing stud thread galling.

Interesting solution. A link to where I can purchase a set?

It seems that nhjohn beat me to the punch.


So as most of you all know, the contract with Hoosier to supply the current FV tire ends this year. So, I contacted Topeka yesterday and asked them about this issue.

I was informed that they plan on sending out a survey shortly to the FV community via e-mail. That being said when this will happen I am not sure. However, if you all see the survey please make sure a link is posted here. That way people who they miss can answer the survey.


As for what they plan to ask in the survey only they know.


But I can think of a few items:
1 - keep the current C4000 series spec tire.
2 - revert back to the old C3000 series tire.
3 - go to a street tire like the Challenge Cup or DriverZ Cup use.
4 - a new slick tire.


Hope this helps some.

While voting to make the Challenge Cup/Driverz Cup /NEFV a regional clsss with radials may sound like a good idea, I'd be cautious. With the close ties between SCCA and Hoosier I would venture a guess the Yokohama radial would be replaced with a spec Hoosier Radial. Yokohama is in business to sell tires on a global scale and Formula Vee is but a mere spec on their bottom line. Hoosier on the other hand is in business to sell race tires and from a profit standpoint, producing a tire that lasts for 3 seasons does not make economic sense. It will be interesting to see what happens and how the survey is worded.

I disagree, Al. You are right about the money and the business aspects, just follow the money and SCCA motivation.

The whole point of CC/DC/NERC(Northeast Radial Cup) is to save money for the racer. Making it a regional class unites us all and gives us power in the huge numbers we have. And those numbers are growing in the NE. If you look at the standings after two events, there are 21 radial drivers that have points. And for a number of external reasons, there are about 6 more that should be there later this season but haven't run yet.

John F and I are VERY cognizant of what's at stake and we are being careful so as not to ruin the great programs that are already established.

One thing nobody has mentioned is that Tire Rack is a major SCCA sponsor, and they carry Yokohama. I'd say that should carry some weight as well.

I love the Yokos. I'm about 50 heat cycles in. Not one of us has any interest in a tire that doesn't last a couple seasons at least.

[DannyPip]

I personally don't want to force a switch from slicks to radial spec tires. If anyone wants to run slicks, fine by me.

We only want the ability to run the Yokohama/5.5" rim/1075 pound Challenge Cup spec from now on. We don't want to play testing games or wonder if we can run next year. We want a regional class, period.

We have proven that we can run both tires together safely and competitively. It is emphatically clear that "the sky is falling" folks were wrong.

Actually agree,
However - I see it this way. We have always said, if Hoosier can make an "equal tire"
- we would be fine with a proper transition time.
Equal:

• Same cost (which I doubt can happen)
• Same longevity (assuming 5 to 6 race weekends per year as a baseline) 2 to 3 seasons
  I personally run 10 to 11 weekends - your choice may vary
• combination rain - dry tire
• current Challenge Cup wheel specifications
• same size front and rears

I look at this as an opportunity for SCCA for an increase in FV's within SCCA.

At this point, there are too many of us that are ALL IN with our selection of tires and rims. If SCCA goes a different direction - so, be it. We have more than enough in an already successful series. Be nice if we are all on the same page.

I agree with everything, but the inclusion of SCCA is scary. There would be nothing preventing SCCA from mandating a Hoosier radial..

[DannyPip]

To circle back around, I spoke to Hoosier Tire East in Connecticut about a month ago.

They informed me that a) the Hoosier Radial "test" tires were unavailable for purchase and b) that SCCA extended the spec tire for 3 more years.

Was at LRP and yes, slicks and radials raced togrther just fine. I say FV should be be able to use slicks or any radial (195/50, 5.5 wheel) at any race for 2026.

I was given a set of Hoosier Radials to evaluate on the West coast. Not sure what compound, but just the fact that they have 50% more thread should make a big difference in longevity. They will be running cooler helping the compound to last longer. This tire is from the rally cross line. It's stated retail price is very similar to the stated retail price of the Yoks.

We are simply not going to be able to evaluate the type of longevity you have stated in a few tests. That is why I believe the new
FV tire rule should be open to any appropriate radial/wheel for the next few seasons.

What is the downside? Those groups wanting their own specific tire can do so within this frame work and other choices can be evaluate over a more appropriate time period. Make it easier for the slick runners to make up their minds about a change.

First of all, it was a pleasure meeting you in person and having a chat.

I don't agree that any tire in 195/50R15 should be able to be used.

The spec that Challenge Cup came up with is a 200 treadwear street/autocross tire that is available to everyone. There is no treadwear rating on the Hoosier, so it should NOT be scored. It doesn't meet the spec. Tested, yes, absolutely for those who want to do that.

All that stuff you say about the Hoosier radial: 100% conjecture on your part. You haven't run them(and neither have I) and have ZERO data, especially on tread temp, compound, and carcass temp during and after a run. You have absolutely NO idea how they will behave over time, none of us do.

So, before you state your opinion, give us data. Otherwise, keep your opinions, yeah?

The entire point of the Challenge Cup is that one inexpensive, very long lasting tire can be used anywhere I want to race. I race in the Northeast, and in Challenge Cup. I also plan to go to Road Atlanta in November and maybe hit some more of the DriverZ Cup events next year. All on the same spec.

Makes sense, doesn't it?

[Hardingfv32]

Yes, nice meeting everyone at LRP, although at my age it is now just a social blur to me.

1) Using the thread wear score is pointless. Only of relative valve among a manufacture own product line. Testing varies among manufactures. Google the facts. The whole debate about race tire longevity is pretty nebulous. The Yok camp is really relying on driver opinion. Drivers that have different levels of driver skill, car preparation and track conditions. You have no well developed test data to back up the Yok hype.

2) My opinion on the Hoosier radial is based on sound science and logic. I am sorry you do see that. It is doubtful you will believe my test data any more than I would yours for the Yoks. The Yok users have a strong bias toward their use which is understandable.

3) My thought about allowing any 195/50 is to allow for comparative evaluation. It would in no way restricts the Yok series. Any decision on a SCCA level tire spec change is probably three years out based on what has been stated.

Half of the Yok radial races are not SCCA events. Does the SCCA FV tire rule really need to accommodate them and do the Yok users really need SCCA approval?

I believe both the SM and SRF cars were on Yoks at one time and now they are on Hoosiers. Can you see the trend? I would say that if there is a push for a FV radial, that Hoosier is going to have an inside line, especially if their new radial is any good.

It's treadwear, not thread wear. I disagree, the treadwear rating means that the rubber compounds used must be similar. No cheater tires. There is plenty of data out there from the CC crew, they've been running them for what, 7 or 8 years now? I don't have a lot of data? Have you looked at race monitor? The lap times speak volumes. It is clearly not hype.


2) My opinion on the Hoosier radial is based on sound science and logic. I am sorry you do see that. It is doubtful you will believe my test data any more than I would yours for the Yoks. The Yok users have a strong bias toward their use which is understandable.


No, you have an opinion. You have zero data, only conjecture. If you had data, I would believe it. "Sound science and logic", that's funny. I have 50 heat cycles, and I'm faster this year than last year, same track, same tires, and most importantly, other drivers running very similar times(within .5 second plus/minus) from the previous year. See, that is actual data. Believe my data or not, totally up to you. I may have a touch more experience this year, but 1.5 seconds faster(for me) at LRP isn't all experience. The tires aren't slower after 50 cycles PERIOD(last year at LRP was cycles 10-13).


3) My thought about allowing any 195/50 is to allow for comparative evaluation. It would in no way restricts the Yok series. Any decision on a SCCA level tire spec change is probably three years out based on what has been stated.


True.


Half of the Yok radial races are not SCCA events. Does the SCCA FV tire rule really need to accommodate them and do the Yok users really need SCCA approval?


It isn't up to you where I race and why. In the Northeast, NER is all SCCA weekends. So yes, that's why we need a regional SCCA class in the Northeast. I like racing NER and CCS. It's great to have options. I'm fortunate that both groups are accessible to me. Why would a regional Yokohama class scare you?


I believe both the SM and SRF cars were on Yoks at one time and now they are on Hoosiers. Can you see the trend? I would say that if there is a push for a FV radial, that Hoosier is going to have an inside line, especially if their new radial is any good.


Yes, I can see the trend of money, sponsorship, and SCCA forcing the hand and tipping the scales in Hoosier's favor. It won't matter if the tire is good if it is THE spec tire. ***See current Spec slick pricing, lack of durability, and inconsistency for all the info you need.

The whole premise of the street radial is fair competition(nobody has to buy new tires to win), FUN, and saving lots of cash on tires. Justin Zarzcycki set the fastest lap of the weekend on 25 heat cycle Yokohamas. He has been within a few tenths on either tire. There is your data.

[Hardingfv32]

1) Let me state that 'at this point in time' I have no objection to slicks and radials running together at any level of SCCA. Do have an appreciation for Hoosier's SCCA involvement. Also believe slicks are a more difficult tire to extract maximum grip from. But if competitors insist that radials are the way to go, then I am confident the Hoosier will have something to offer.

I will have a set of radials the next time I come East. It offers me a better selection of events to chose from.

2) Thread wear, I dare you to find how any manufacture develops their thread ware 'number'. Get real! How is anyone going to get a 'cheater' tire? Is Yok or Hoosier going to make it for them?

3) How to compare radials:

A) Zarzcycki was clearly the class of the field at LRP, but how we separate driver , car, and tire performance measures? Could a great driver and car combination be making up for poor tire performance? What science do you use to measure this?

B) A lot of generalizations about Yok longevity. I understand how they are generated and might be considered valid. But here is the rub, how does SCCA make any conclusion about which radial is better. There is no way any other radial is going to be used enough to form the generalizations that have formed around the Yoks. What form of scientific comparisons can be made in a short time period? How do the Yok users prove that the Hoosier does not last as long for example?

4) 'Half of the Yok radial races are not SCCA events. Does the SCCA FV tire rule really need to accommodate them and do the Yok users really need SCCA approval?'

How in the world does the statement imply anything about where you can race. Where have I stated anything against radial regional SCCA classes? Your bias against me is causing you to make things up.

Brian

[Matt Clark]

I am a little concerned with SCCA getting involved with it, beyond adding a rulebook line (similar to what they do for a few topics with FRP) that simply says they will allow the "Cup Tire" that Challenge Cup specifies. That leaves it up to us to test & dictate what that spec is, not SCCA. Challenge Cup & DriverZ Cup have had success -because- of our ability to run things our way so far.
I think it should be listed as FVC, not FVR & open to any radial tire people want to try. If you want that, don't mess with the people who want to conform to Cup tire rules.

As I have said in several Facebook posts thru all this, I find it absolutely amazing that not a single person involved with radial tire FV racing here for a decade+ has been asked or involved with anything "new". It's almost insulting.

One of the key points about picking the tire we did, was to pick a widely available tire that is not just for FV. We are too small of a market. We made a list of several "must meet" goals, and it happened to be that the Yokohama met those best. Is it ideal for a FV? No. But it does the job very well & has proven to be very popular.
That being said, I also know there are staunch anti-Hoosier people out there. I am not one. I wanted people to push Hoosier to build one, but Hoosier has apparently repeatedly said they will not make a standard 195 series TrackAttack offering. Simply making a treaded radial tire could still end up in the same boat as we are with the slicks, with the unhappy users.

[DannyPip]

Ok, Brian, RE: your post #78

1) If the slicks were more consistent, more drivers(meaning not so much experience like me) could extract more out of them.

2) Challenge/dare accepted. It was easy to find honestly.

https://www.tirerack.com/upgrade-gar...NFBwNjzqiLQ8KQ

Read above article first, then come back here. The UTQG standards were used to ensure treadwear rate compliance. X miles= Y tread worn. Same car, same conditions, same loop.

3) A) What science are you using to discount offhand the lap time info I posted? I can post screenshots if necessary, but is it really necessary? It's all easily verifiable.
B) Test the tires. They have three years to make a decision. The bottom line is that we simply don't care what the SCCA does with the spec tire. We just want to run our combo and let others run theirs.

4) Totally missed my point. I guess I should have been more clear.

We have a 2nd year of "testing" radials in the Northeast. Supposedly, that expires at the end of 2025, just like the "one year of testing" we had on the books for 2024. We had a bunch of sets of Yokos and a bunch of people tried them and liked them.

We have about 25 guys on Yokos that couldn't care less about testing, they've already made their decision on what to run. We want a regional Yoko class on the books permanently so we're good to go. Since all the tracks and events in the Northeast are SCCA, that is the obvious direction to go.

I don't have any bias against you. You seem like you just need to disagree with everything.

Yes, I really like the Yokos. They work for me, and I am slowly getting quicker as I learn my car, my tires, and the limits of myself.

You, sir, are obviously a Hoosier fanboy. You talk to me about science and facts but you have NEITHER about the Hoosier radial experiment. Not very scientific.
