Picked up a staggered set of 19" wheels for my 98' LS1 Firebird. Just wondering what tire size can be run without problems, and I dont neccesarily mean the speedo just being off because I can deal with that.

Right now, I'm looking at running 275/45/19 on the rears and 255/40/19 on the front. As far as i can tell, the rears are not going to rub because with 500+ lbs of human being sitting on top of it the fender still cleared the tire by at least 1/2". I have not fitted the front yet, and I'm wondering If i should anticipate any problems with that size either on the front or the rear. I know the tire is a lot taller, and as for width it doesnt appear to be an issue.

For reference, this means that the rear tires are I believe 28.6" high and the fronts are almost dead on 27" high.

The other option I have is to run the 255/40/19 on the rear instead and go with a 235/35/19 at the front.

Thanks

 

Why such a tall tire?
