Is that a bias ply tire? I ran MT Sportsman Pros on the street that were bias and I hated them. One of the best things I did for making it better for the street was getting a radial tire for it (MT Sportsman S/Rs) I run a 31x18.5x15 on the back of my Demon. Great idea converting that car over for the street. You'll have more fun with it than just having it for track only IMO.
