Help! Wrong tires?

[EYERACE]

I have not tried to mount them yet. Do these Yokohamas fit on 8 inch and 6 inch rims? Because they're marked the sizes they are I'm not sure. I cannot find online any sort of conversion table from the 22 X 9 X 13 or the 20.5 X 7 X 13 to the Yokohama sizes as 200 / 550 / 13 rear and 180 / 515 / 13 fronts.

Try this chart:

If you are looking for a format you are more familiar with how about this: ?

21.7 x 7.9 -13
20.3 x 7.1 -13

apparently they are the wrong tires for 6 front or 8 rear. thanks for the chart.

The first number is tread width in MM (25.4 to the inch).

The second number is the overall diameter, again in MM.

I have Yokohama tires on my FC. The sizes match the ones in Eye's original post...200/550 and 180/515. I got them from Bob Wright (Yes, Bob, I STILL have them). He had run them on his FC.

the yokohama chart from the link makes it look like the rim sizes would be 10 and 8 with a plus/minus size of 1/2 inch.......but after doing the math conversions, indeed it makes the argument that they will fit after all.

like Lawrence Welk used to say to the band at the end of the show....."Thank you boys!"....and thank you Apexspeed.

From what I recall, those sizes are larger than the FC Avon rain tire size. The Avon rains are 160/530 adn 180/565
