i'm not sure, depends if the guy has the tires and rims balanced. you'll find out once they're on and you his about 50 mph. vibration=get them balanced...no vibration=your all set. we might be goin tot he track tomorrow, i wont be racing though
here's a tire size calculator . you put in your stock tire size and the new tire size and it will tell you everything you want to know. for yours i put in 205/70/15 and 235/45/17 and the new tires came out to be 1 inch shorter.
