Pro-Line Ion SC tire
The Pro-Line Ion SC indoor clay tire was designed from the ground-up and requires zero break-in tine. The unique molecular structure tread design provides forward and side traction and 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. The new tire already proved its performance by taking the ROAR National Championship in Pro-2 SC in the hands of Ryan Cavalieri.
