The R-A4 from Radar is an all-position tire designed to deliver high mileage on and off the road, excellent wet and dry traction, and a long wear life. Ideal for mixed service use, the tire is made from an advanced tread compound optimized for excellent on- and off-road mileage and great fuel economy. Three circumferential grooves channel water away from the contact area to reduce the risk of aquaplaning, providing confident traction and water evacuation in wet conditions. The sidewall ribs protect the R-A4 from damage caused by impacts and scuffing.
