My Duster DOES NOT like mixing bias and radials, either front or rear combinations It(me ) does like bias with bias or radail with radials, bias in the front with radials in the rear isn't to bad, radials on the front with bias on the rear makes me think I've went back to drinking I don't run a big, fat front tire on either set, 26x15 ET fronts or 165x15 radials on the front, both sets are on 4 inch rims this is only on the street, at our local 1/8 mile track the car deosn't talk (act up)to me at all with mixed tires 6:90 at 100 MPH
