tire size help please
on my 95 GT, i just noticed that i have 255/45 on the front, and 275/40 on the rear. i understand that i have the wider tire in the rear, but why would my front tires have a thicker wall than the rear. now that i noticed it, it is very prominent and looks weird. is there a reason?

255/45-17 was the stock 94/95 Cobra size, I actually ran that size up front with 275/40s in the rear and the difference in size really wasn't noticeable. 275/40 up front will likely rub at full turn unless you have 03 Cobra A arms, but it also depends on the wheel size and offset.

245/45/17 was stock GT rubber.
45 percent side wall of a 245 width tire will be a lesser number than 45 percent side wall of a 255 width tire. People go 275/40 on the rear to get more bite and keep side wall profile similar. 40 percent of a 275 width tire gives you close to equal diameter on both wheels visually
A 245/45 tire will be about 25.4" tall
A 275/40 tire will be about 25.5" tall.
A 255/45 tire will be about 26.1" tall.
Exact size will vary by brand.
