I bought a 1991 Silverado 1500 with 6 lug wheels. The front have Dunlop Rover Tires. The rear have Jetzon Revenger A/T tires. Anyone heard of these and kn ow how they perform? Also, does anyone know how the Dunlop Rover perform? I remember being in an Xterra with the Dunlop Rover and that suv felt like it was on ice trying to stop in the rain.
