Finding a tire that performs year-round is a must for most drivers, as dry, wet, and winter weather conditions all present different challenges. Fortunately, all-season tires are built to handle these conditions, and the Grandtrek PT21 from Dunlop does that and more for drivers of CUVs and SUVs. Four wide grooves and open shoulders force water out of the tread to reduce the risk of hydroplaning on wet roads, and the Grandtrek PT21's dense siping bites into the road to increase traction. A low rolling resistance design enhances fuel efficiency so that drivers can go longer between filling up their CUV or SUV, and the Grandtrek PT21's symmetrical tread pattern fights off uneven wear for a longer tread life.
