Anybody running a 265 series tire on an 18x8 inch IROC wheel? I have seen a few running a 255 series tire but not a 265? I was wondering if it would bulge too much? Any opinions welcome

 

yes, however knowing the intended profile would help.

here is a comparison with a stock spec 18" setup to something similar in a 265..

Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
245/40-18 3.9in 12.9in 25.7in 80.8in 784 0.0%
265/40-18 4.2in 13.2in 26.3in 82.8in 765 2.4%

235/245/255 is the only ones i would go with on a 8" rim. preferably 235 if you like the european look and 245 if you want a straight wall.

 

I opted for 245 high performance summer, over the 255's. With the suttle tread and nice rolled edge, the 245's almost look like slicks and look really good on 18" IROC's.

 

post a pic of them on the car man.

 

Love Too, but right now I have winter tires on the stock rims mounted...

All Apologies
