Bridgestone DriveGuard 245/45R17, All Season, High Performance tires.

Features and Benefits: Run flat tire model; All season traction; Longer lasting usability; Bridgestone DriveGuard TiresThe Bridgestone DriveGuard is a performance and high performance, all season tire manufactured for passenger vehicles and SUVs. This model has some touring sizes as well. Bridgestone offers a 50,000 mile treadwear warranty with the W speed rated sizes and a 60,000 mile treadwear warranty with the H and V speed rated sizes. This is a run flat tire. It features a reinforced internal structure in order to enable its 50 mile, 50 mph performance once air pressure leaves the tire. This allows the tire to maintain the ideal tire shape when air pressure loss occurs, which guarantees a safer, limited, temporary drive. Run flat tires should not be mounted on the same vehicle with regular tires, due to the difference of their internal structure. All season traction is guaranteed with the tread design and the all season compound. This combination helps to improve the dry, wet, and winter weather traction. The detailed tread elements firmly grip the road surface with extra biting edges, while the compound keeps the rubber flexibility in various weather conditions. The optimal groove pattern disperses water and slush from the footprint, effectively avoiding hydroplaning in wet conditions. The Bridgestone DriveGuard promotes a longer lasting usability. The tread design's even pressure circulation avoids irregular wear, boosting the tire's service life. The compound also utilizes the wear-resistant elements to decrease the treadwear rate. The stronger compound and the durable structure work together to protect the tire from tread and casing damage. They avoid damage to the tread area, while the structure protects the casing from punctures, cuts, and impact damage. The combination of these elements greatly enhances the model's overall tread life length. 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.
