This is the Pro-Line pair of Front/Rear Ion SC 2.2 /3.0 M4 Super Soft Tires and Closed Cell Foam Inserts.
Pro-Line’s ION tires have proved electrifying from the start, taking the ROAR National Championship in Pro-2 SC at the hands of Ryan Cavalieri! The ION was engineered and designed from the ground-up to be the ultimate indoor clay tire that requires a zero break-in period and gives you ground breaking performance.
Its unique molecular structure tread design provides unbelievable forward and side traction not yet achieved in any indoor race tire to date. Even with the ION’s super-low tread height, maximum wear is reached by the alternating dual center lugs. Pro-Line’s ION is extremely easy to drive due to the super-smooth side tread that flows organically out of the tire sidewall.
