The Accelera Phi is a high performance, all season tire manufactured for passenger vehicles and SUVs. The tire promotes superb controllability with the maintained road contact and the special rib design. The shoulder tread block sequence increases the cornering ability and power, while its variable pitch design lowers the road noise generated during the drive. The compound and tread design ensure excellent all weather traction and the five circumferential grooves prevent hydroplaning situations. The Phi's lightweight construction and dynamic lateral grooves decrease the rolling resistance and offer a fuel efficient drive.
