Not BIAS ply but Fiberglass belted radial tires. I have some Pro street Hoosier 29x15x15 rear tires. They are steel belted radials. I would like 28" tall skinny front runners and Mickey Thompson makes them...But...... their Sportsman SR tires (The flame pattern tread) are actually fiberglass radials. Can I safely run Fiberglas radials up front with steel radials in the rear? Hoosier front runners only go to 26." My second option is an all season 205 /75 R15 on a 5" wide wheel but I really want that skinny front runner look. Truck has no significant power (95 Dakota with stock 318) and wont for a long time.
