wrong tire size help

I ran the same sizes on my 94 with no problems. I hope your offsets are correct with that package or you will have rubbing. The fronts (255's) will be about 1/2 inch taller than the rears, if you can live with that you should be fine.(I couldn't) 245's do fit on a 9" rim, and that would be my recommendation.

You'll never notice a difference. I have 235/45/17s up front and 255/45/17s in the rear and the rears dont look any taller than the fronts.

Here is a good site that will show how much difference there will be between the two sizes.

the middle number (45, 50, 70 w/e) isnt the height of a tire its the aspect ratio

its just a percentage of how tall the tire is compared the to width


say you have a 255/50/15 tire the tire is 50% as tall as it is wide so its roughly 127.5 cm tall which is about 5 inches tall. which is 10 inches for the whole tire and on a 15 inch rim it ends up being 25 inches tall

the rim u posted for the will be 114.75 cm tall which is about 4.5 inches, 9 inches for both side so it ends up being 26 inches tall

the rear rim will be 110 cm tall which is 4.3 inches, 8.6 for both sides and it will be 25.6 inches tall

your rear wheel and tire will be .4 inches shorter than the front. which isnt much and i will doubt it would be noticeable but who knows

yes it would match perfectly .02" is less than a 32nd of an inch and you wont be able to see that for sure.
