This is a pack of two Pro-Line Electron T 2.2" Off-Road Truck Tires. The Electron shares close family ties with Pro-Line’s popular ION tire with the iconic dirt grabbing center tread and futuristic styling. The Electron features connected tire tread technology to improve traction and wear on even the most abrasive of indoor track conditions. The square center pins laid out between the connected tread provide consistent forward and side bite even when the track gets dusty. Test drivers are amazed at the precision steering and super-fast corner speed that the Electrons provide.
