tire size
 

I have stock 99 gt rims and its time for new tires. i have 275/40/17 all the way around , i was wanting to put dr on the back. What is the biggest size i can go on the back. My car is lowered a little bit and i want to keep the rims i have. Thanks for the help.

If they are the stock 17x8's I wouldn't go any wider than 275.

275max on a 8" rim out back. Thats how I roll.
