This is a pair of Resistor 2.2" Rear Buggy Tires. Based on the ground breaking carcass shape and futuristic directional tread design of the Positron, the Resistor takes performance up another level with improved side bite and balanced traction on indoor clay tracks. Each bar has been positioned and angled for maximum race performance. The Resistor is directional, which adds another tuning option for the racers always looking for that extra edge since it will perform differently depending on which direction it is run.
