The Vredestein Fortezza TriComp is excellent for training and racing year round in all conditions. The TriComp Vredestein rubber formula gives you softer shoulder tread for maximum grip in the corners, while harder center tread provides a longer wearing tire with less rolling resistance on the straights. Race winning seconds can be lost due to flats. No worries with the Fortezza, it's got a layer of composite down the center of the tread for extra puncture resistance. Extra rubber over the tire's shoulders holds your line under hard cornering, giving you predictable turns at any speed.
