AKA Racing Impact 1/8 Buggy Tires, in Medium compound. These tires DO NOT include inserts, allowing you to use the tire insert of your choice. 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 the ENDURO and WISHBONE tires and is available in all of AKA's proprietary compounds from super soft to hard, with and without inserts.
