Accelera Phi-R OVERVIEW The Accelera Phi-R is a performance and high performance, depending on the speed rating of the specific tire size, all season tire made for passenger vehicles and SUVs. Accelera offers a 50,000 mile treadwear warranty with this model. This model offers excellent all weather road grip and its traction is superb in dry, wet and winter weather. The tread elements and the tire compound work together to boost the year round traction and to maintain tire tire's flexibility even in colder temperatures.The tread grooves help make the driving experience safer by channeling water and slush from below the footprint of the tire, thus avoiding dangerous hydroplaning. The tire has a lowered rolling resistance thanks to the reduced weight of the tire. This contributes to two enhancements. Firstly, the lowered rolling resistance decreases the fuel usage of the vehicle, as it does not need a lot of energy to keep the tire in motion. Secondly, it slows down the tread wear rate of the tire, as the driving pressure is eased off of the tread. These aspects make the tire more economic and environmentally friendly. Even at high speeds, this model performs exceptionally well. The improved driving stability of the tire and its precise steering responsiveness provides extra safety. The tire is easily controlled and it responds to the commands of the driver quickly and precisely. The upgraded cornering ability and power also boost the high speed driving safety of the tire. The tire grips the road and provides first-rate traction in cornering and maneuvering situations. The Phi-R is a quiet and comfortable tire. The road noise heard in the cabin of the vehicle is reduced by the additional sipes in the tread pattern which channel the soundwaves through the model's footprint, making an enjoyable 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.
