I know the proper size for my 17x8 '01 cobra rims is 245/45-17 but I've heard that Nitto's run small/narrow and I was wondering if it would worth putting a 275/40-17 on there instead? I know its designed for a 9" rim but I could certainly use the extra rubber since I'm putting down almost 500 at the wheels. A little bulge on the sides wouldn't bother me too much, would it bulge too much. What would you guys do? Thanks.
