I've use several different types and sizes of tires on the front, M/T ET fronts, 24 inch, 26 inch, Moroso 7.10x15 and the 165x15 radails mounted on a 3.5 or 4.0 inch wide rim. I have mixed then with radials on the rear, M/T ET Street Radials and with the M/T ET Street bias plys, which is not a good mix on the street At the track with no ruts the car drives fine , it doesn't matter which front or rears I mix them with at the track My car runs 128. MPH, not 130 yet It does weigh 3450 with me in it at the track, goes straight as a arrow, usually, at the track It does wonder, hunt, and drive bad on the street mixing radials and bias plys
