so i have a 68 cutlass supreme, and i want the widest things i can put on.

also how wide of a rim should i have

 

Hi there; The width of your tires will dictate the width of your rims, I run 255.60X15 on seven inch rims with lots of room...the backset of the wheel will also determine what width to use without rubbing on the inside...

 

There should be some previous threads on this, try the search tool and see what you find. With the correct offset wheel I believe 275's will fit. John

 

alright, thanks guy
