The IMPACT tire features a dense small square lug pattern with offset lug rows in the center of the tire to deliver maximum forward traction and good wear characteristics. The two outer rows of lugs are parallel to create a circumferential groove at the edge of the tire to give the tire very predicable side bite. This allows the car to rotate in the center of the turn while still feeling very stable and predictable. The IMPACT is built on AKA's latest carcass design featured on our ENDURO and WISHBONE tires. Super Soft long wear is developed to work in colder conditions where the track either has an abrasive surface or a surface that gets very polished which creates lots of wheel spin and therefore more wear. This compound will be popular in the winter months where drivers are still competing on outside tracks in cold weather.
