Goodyear Wrangler RT/S(P) tires are often used on pickup trucks and vans, and are built to be quiet running. The continuous tread lug design creates a steady contact area with the pavement, reducing the amount of noise created while driving. Some traction is available both on the road and off-road, and the flat tread profile creates added maneuverability on the highway. Radial belts in the tire protect against punctures, enabling safer driving over variable surfaces. These tires come in a variety of sizes, from 28.9 inches to 31.6 inches in diameter.
