FEATURES AND BENEFITS: All weather traction; Fuel efficient tire; Precise steering responsiveness; Longer lasting tread; Puncture resistance; Reduced road noise levels; . OVERVIEW: The Bridgestone Ecopia EP422 Plus (OE) is a touring all season tire manufactured for passenger vehicles. This model is the original equipment tire of select vehicle models.Bridgestone's Ecopia tires are known for their fuel-efficient manufacture. They are made using the NanoPro Technology, which is a special tread compound that uses less energy to maintain the same performance of the tire. The compound reduces the rolling resistance of the tire, which in turn lessens the fuel consumption and the CO2 emissions of the vehicle. The tire is both economical and environmentally friendly.The all season tread pattern, with the added siping details, offers remarkable all weather traction in wet, dry and even winter weather. The tire's light snow grip is also enhanced with the additional biting edges the extra sipes provide. The tire is resistant to hydroplaning as the circumferential tread grooves help disperse water from below the footprint.The tire's performing capability is also first-rate. Its flat footprint and maximized road contact area ensure that its steering responsiveness is quick and precise. The tire responds swiftly to the commands of the driver and performs as desired. With the good steering responsiveness, the tire also provides good road feedback, making it safer to use.The reinforced structure of the tire also extends its life. The tire resists punctures and other damages, such as chipping, tearing and cracking, as its structure is reinforced. The stronger tire compound used in the manufacture also prevents irregular wear and it forces the tread to wear out evenly. As the tread is even for the tire's entire lifetime, it is usable for a longer period of time.The Ecopia EP422 Plus (OE)'s tread pattern helps eliminate the road noise generated while the tires are in motion. The road noise heard in the cabin of the vehicle is decreased, making the driving experience more comfortable. 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.
