Tire - Karoo* 4 - Rear - 140/80R17 - 69Q The new design is intended to increase the off-road performance level, especially on soft surfaces, such as sand, mud and clay. As for the road, the engineers have worked to improve in particular the overall handling and the behavior on wet, especially when leaned over on the tire*s edge, The new tread design definitely has a more aggressive off-road look with bigger cutouts and alternating side-knobs that would appear to clean out better in soft terrain than the old Karoo* 3, Like its predecessor, the Karoo* 4 is made for adventure and dual sport riders who want good off-road performance and longevity in a 50/50 tire
