So my tires are starting to show their age, and it's time to replace them. I'm currently running the stock size of 205/75/r15 on the stock 1984 M-body wheel of (I think) 15x7. IMO, there is not enough tire under the car, and I think it almost has the "pizza-cutter" look, especially in the back. Again, just my opinion. I'm going with the traditional BFG radial T/A with the white letters. I've been doing some research on different tire sizes and seeing what will work. This is what I found: For the front, I'm thinking 215/70/r15, and that should be just a little wider while allowing enough room for full lock-to-lock steering. The rear is where I have more questions. I'm leaning towards a 255/60/r15, and I took some measurements today and I'm pretty sure they will fit, but I don't want too much tire bulge on the sidewall. Does this seem like too much tire for the rear? I do like the fact that there will be more tire on the ground. Any input is welcome.
