I've searched the forum plenty of times and still haven't found what I'm looking for. I just want to know what is the Widest tire I can put all around on my 99 Mustang GT, 35th LE if that matters, yet I think the body is the same as the rest of the 99's. Anyway, I'm hopeing I can fit 275/45's all around, or could I go wider?

 

275/40/17's in the front and 335/35/17's in the rear.

 

Without spacers, any rubbing or anything? So I can safely put 275/40/17's all around?

 

You can stuff a 9 inch wide rim with 275's on the front, barely. Turning radius MIGHT be affected, but it really matters on the offset of the wheel you have.

Like JD said, 335's in the rear if you have a wheel that can handle all that rubber.

 

ive been drawn to sumitomos all around
275 up front and 315 in the back
on 17x9,and 17x10.5

from what i have heard and researched, there will be NO problems at all with this..
i think code3 has 335's though, ask him what he thinks about it for a better opinion
