    Smaller Tires

    What will happen if I go from 33" diameter tires to 29" diameter on the rear of my Blown 72 Skylark? I'm running 3:70 gears in the rear and the car is street driven only. The car has 33 x 18.5 x 15 M.T. on it now.

    At 70 MPH you go from about 2640 RPM to 3000.

    Thanks for the reply. I have a chance to pick up some new M.t. sportsman tires that are 29 x 15 x 18.5 for a very good price. Guess I will go ahead and get them. Thanks again.
