Mounted 255/60 R15 on rear

Have always wanted a slightly larger rear tire on my 1985 Z28. Did a lot of research and settled on these 255/60 R15 to mount on the stock rear wheels. Front still has the stock size 215/65 R15. I think I like the change. It is very subtle and not even particularly noticable to most people but I'm already getting more compliments on the car. It raised the rear up just a little, which I like because the car has always looked slightly squatted down in the back end.

Here are before and after pics. I dont think the pictures show the improvement very well though. I took them at just the right angle so you can see the difference in tire size. From most angles you dont really notice the difference in size and the stance just looks better and more aggressive.

Should get a bigger tire up front as well.

Looks good I've always liked having bigger rubber in the rear.

Typically I don't like bigger tires out back, but overall I've gotta say your car is beautiful!!!!
