Jconcepts Sprinter 2.2 - 1/10 Buggy Rear tires Blue soft The Sprinter tire is designed to bridge a gap between the popular Double Dees and other pin tire options from JConcepts. The Sprinter tire has square, angled pins that are stacked vertically to flex and fold evenly across the tire. Typically, a stacked tread will wear less and provide more forward bite while the aligned space helps rotation in the turns and gives a snappy release to square up quickly. Starting with the new tread, the team focused on durability and performance to bring a rear tire option to market that competes on loose surfaces which are wet or dusty.
