hey i have a 91 formula with the stock ws6 wheels. i want to throw on some nitto 555r's can i fit a 275/60-15 on them? if so are there any fitment issues? oh yea it would be for the rear.

arent the stock formula wheels 16x8's? atleast mine are lol.... so a 275/60 R15 will definetly not fit since its designed for a 15 inch rim.... if you have 15 inch rims i believe their 15x7's... so a 275 is really pushing it for a 7 wide rim since i believe they usually require atleast a 7.5" wide rim...if your looking to keep a somewhat close overall diameter then a 275/50R15 would work better if you have 15 inch rims... if you have 16's some 255/50R16 drag radials will work....

 

Ditto. If you have 15's, you dont have a formula.
