The JConcepts team consistently looks to enhance racing performance while doubling down on original designs destined for championship results. The Relapse, now available as pre-mounted, is a tire derived from research and development put into tires such as the Detox and Rehab. Those results were incorporated into a new design optimized for indoor and outdoor track success while delivering more forward bite than the original incarnations. The JConcepts speed laboratory started with the center section of tread for more horizontal pin contact.

The design revolves around the center structure which has medium to small sized, dense lugs arranged in a stacked and horizontal configuration. The lugs have strategically placed cuts and grooves to allow flex in dust to perform when the track is in a deteriorating condition. The outer portion of the tread fits together like building blocks, with shapes placed together that nest well but also work together to flex laterally to provide steadfast side-bite. The tread tapers off cleanly to the outer sidewall giving a smooth transition during hard cornering.

The Dirt-Tech insert, popularized by its durable nature and gray color, will give customers the combo package they have come to expect from JConcepts. Genuine, Mono 83mm wheels are used in this pre-mounted combination available in bright white and florescent yellow.
