i have these rims

Group A, Inc. - Your Source For ROH, Simmons, and DeZenyo Wheels

the 17x8.5

and the tires im looking at ar 2 new Pirelli race tire 305/645 R 17

i dont know but they say race tires are sidewall measured in mm not in aspect ratio. so the sidewall is 645mm? says Width is 305mm, height is 645mm. these are going on the rear.

ive seen pics of the dide with the 315 wide tires on his trans am vert... and that looks a bit too much, however i could live with it if mine are a bit thinner, and wouldnt rub too much. however i dont know how wide his rims are. ive searched over the boards, and on google etc...

it looks like truck tires this size fit 8.5" wheel, but thats with a 70r sidewall...

i dont know

 

whats up. im not to sure what the side wall height is like that for a "race tire" but if its 645mm that would be 25.4 inches. maybe means the total height. but if its right i have a 275/40/17 on a 9 inch wide rim and the over all height of the tire is about 25.66 inch. that tells me you would have less side wall then i do and there is noooooooooo way you will fit a 305 on there. i tried a 285 on my 9 inch rim and didnt happen.lol max is a 275. im not sure what the measurements are you posted so if im wrong im sorry but maybe it will help you a lil bit

 

ok cool thats all i needed to know.

 

315's si square on 11 wides, they barely fit on 10 wides. 305 are 10 mill skinnier, but that ain't enough....

 

Do you know what brand of rims that make a 17" rim with a 10.5" width?
