Hey again, I need some tire sizes for my new wheels, the fronts are 15 x 4 pro stars and I was thinking 165 85 15, more importantly the rear wheels are 15 x 8 and have 5.5 inch backspacing, I am going to remove the quads as I am installing beefier upper and lower control arms but I need a tire size, I was thinking 255 60 15 or can I go bigger, I dont want to have to roll the fender lip, thanks guys any help is appreciated

 

I'm not sure if they had rolled fenders or not but I know a few guys that ran 275/60 on 15x8 drag lites.

 

Some have run 275's out back, but it also depends on the tire brand as some are narrow, or some are wider with the same specs.
255 is safe, as many have gone with that size.

 

!low has said it perfectly but Chad is bang on to.

 

Good point, I don't remember what brand they ran.

 

Even I have noticed a difference in tires just on the Mustangs I have owned. The 90 05 and 09 have rounded sidewalls where the 99 had a straighter wall

 

Yea I know what you mean about the 99. I had a 2000 with the Good year Eagle tires and found the sidewalls very flat. I hated those tires.

 

really how come

 

The sidewalls started to deteriorate really bad with big blotchy rough patches and looked like crap. I was really bent out of shape over it as I kept that car absolutely mint and when I shined the tires up they looked like crap. Goodyear wouldn't warranty it as it was only cosmetic. When I argued that the car was a "show car" and the look meant alot to me their argument was that it was probably my tire dressing that caused the issue. I expressed my concern and explained that if tire dressing could damage the tires I was worried about what the road could do to them. I got nowhere and vowed to never buy another Goodyear tire and haven't to this day.

 

I can understand that. I have not had Goodyears since the 99 myself lol
