Tire pressures you're using? Last four-wheel alignment? Was a printout provided? Last time the suspension's components were thoroughly checked? Expensive tires as in? Cheap tires as in?
Correct. Running a staggered versus square setup. Can't rotate front to back merely left to right. Since it isn't the alignment nor suspension/steering related nor improper tire pressures nor frequent burnouts then best of fortune locating the solution.... I have 275/30/20 in the rear . And 245/35/20 In the front...
