That's my point you can't prove it at least not to my knowledge which is why I asked the question. Will anyone challenge it? I doubt it. We have strict rules now on engines and people still show up and run 3 sec a lap faster the weekend after they rebuilt their engine in their garage. Trust is not so easy when everyone is trying to win, there will always be someone that will break it.
Fast guys will end up with a brand new set that is only used for wet and a shaved set that last 2 years not 5 like Greg said. Also like Greg said shaved is not proven to be faster yet on these tires but if 2 year old tires are faster just from wear i'm willing to bet they will be and the faster racers will buy them.
Don't get me wrong I think this formula with the tires, wheels and weight is a good thing.
I only mentioned aluminum wheels because it would be nice for the heavy people to have a option to get a little closer to min weight. If I need to buy wheels I would like to buy them once and if I had a chance to get a aluminum wheels that are lighter for a few hundred buck it's a no brainer.
