OVERVIEW: The Thunderer R200 is a highway terrain, all season tire manufactured for commercial vehicles.The model guarantees a secure all weather traction. The durable, all season compound and the detailed tread design greatly improve the dry, wet, and winter weather grip on the road surface. The siping placement and the tread design greatly improve the grip on the road surface with extra biting edges. The stronger compound keeps the rubber flexibility throughout the year, further upgrading the summer and winter grip. The circumferential grooves prevent hydroplaning by dispersing water and slush from the footprint in wet weather conditions.The flat footprint and the ribbed tread design improve the surface contact. These tread elements greatly upgrade the grip on the road surface with extra biting edges, boosting the steering responsiveness and driving stability. As a result, the tire promotes great steering response time and accuracy to the driver's commands, while the structural stability is improved. The rounded shoulder pattern allows the tire to increase the cornering ability as well. These elements grip the road surface with extra biting edges, boosting the maneuvering ability.The R200 enhances the load durability. The stronger internal structure features a double jointless spiral overlay which allows the tire to enhance the load carrying and withstanding ability. As the tire does not deform under the load and driving pressure, the construction boosts the overall load capacity. This promotes a safer, heavy-duty performing power. There might be discrepancies of sizes between brands and models of tires which have this size formatting. As the manufacturers only provide the tire width and the rim diameter with these tires, various brands and models will have size differences. In order to ensure the correct size is purchased, the overall tire diameter that is needed should be checked.The Overall Diameter or O.D. advertised represents the tire's overall diameter in inches, once the tire has been properly inflated and mounted per the manufacturer's recommendation. This advertised number is provided to Priority Tire by the tire manufacturer. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
