Goodyear Wrangler Trailrunner AT. FEATURES AND BENEFITS: All weather traction; All terrain traction; Self-cleaning tread; Reduced road noise; Even long lasting tread life; Driving durability; . OVERVIEW: The Goodyear Wrangler Trailrunner AT is an all terrain, all season tire manufactured for light truck vehicles. Goodyear offers a 55,000 mile treadwear warranty with this model.The multi-angles sipes of the symmetric tread pattern increase the all weather traction and excellent road gripping ability. They maintain constant road contact and it improves model's traction on all road surfaces. The deep grooves and sipes also prevent hydroplaning situations by increasing the tire's water and slush dispersing ability. This further improves the tire's year round driving safety levels. The rugged stepped shoulder design cleans the tire from mud and snow stuck between the tread elements, increasing the mud and snow traction. Select sizes of this model (245 or wider sizes) feature the tire industry's symbol for being able to handle the harshest winter weather conditions, the three mountain peak and snowflake symbol.The sawtooth tread block edges and the rugged stepped shoulder design increase the tire's performing capability on all road surfaces. The model is capable of handling all soft, loose and uneven surfaces with ease. The aggressive tread pattern ensures that the tire is safe to use and will not lose its traction on tougher, off-road terrains. The self-cleaning nature of the tread enables a clean footprint at all times by dispersing mud and snow stuck between the tread elements that block the tire from its contact with the road. It is, however, capable of performing well both on and off-road. As it offers strong grip off-road and excellent comfort on-road, the tire provides great versatility, which makes it perfect for drivers looking for tires that have flexibility.The tire's tread is computer optimized. This increases the tread life and lowers the road noise heard in the vehicle's cabin. The optimized tread pattern regulates the tread wear by spreading the driving pressure out across the tread area. This even distribution of the forces of accelerating, cornering and braking prevents the tire from developing irregular wear patterns across the tread area, which extends the tread life. The computer optimized tread pattern features a variable pitch sequence that lowers the road and pattern noise generated while the tires are in motion. It creates a sound frequency that cancels out the road and pattern noise the moment they are generated. This offers a quiet and comfortable on-road driving experience. 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.
