This is a pair of ION 2.2? Buggy Rear Race Tires. The ION proved electrifying from the start, taking the ROAR National Championship in Pro-2 SC at the hands of Ryan Cavalieri! The ION was designed from the ground-up to be the ultimate indoor clay tire requiring zero break-in period and ground breaking performance that is now available for your Buggy! The unique molecular structure tread design provides unbelievable forward and side traction not yet achieved in any indoor race tire to date. Even with the super-low tread height, maximum wear is reached by the alternating dual center lugs. The ION is also extremely easy to drive due to the super-smooth side tread that flows organically out of the tire sidewall.
