So I have the 21 inch tire option on my SS they are nice looking for factory wheels but dang Prices are crazy and only Perrellis makes that size..

SO the size is 21 rim 8.5 in front, and 21 9.5 in rear..

factory is 245 40 21, 275 35 21..

I have been running 245 35 21 and 285 30 21 no problemas what so ever

my last set cost $250 for 2 new toyo proxis tr1.. yes 2 and 2 hankook for 176.00 each the tread matched ok and the tire walls are so small u cant even read there different brands,

So Im wondering if a 295 30 21 will fit back okay and a 255 30 or 35 21 will fit front..

I DONT CARE IF THE CAR MANUFACTURE RECOMMENDS THE STOCK SIZE! Its probably cause nothing is offered in 21 inch but those lol!

I had a old z28 96 and ran 295 on that 17 x 9.5 ss rim no problems

any pic would be helpfull! thanks guys and gals

 

I had a friend who installed a set of Giovanna wheels on his Camaro and did the 295/30r21 with no problem. He was running a 21x10.0. I drove the car and I did not notice any rubbing or issues. A test fitment is always good.
