The Knobs, simply named for their appearance of the irregular diamond shaped knobs which have step and overlapping features built in. JConcepts believes tire options in the class should replicate those used in major series events in the 1:1 world and the Knobs certainly do. The arrangement, pattern, and instances were a result of carving from an existing 1:1 tire and the results were fantastic. The Knobs excel in dirt or asphalt conditions where massive edging of the pins helps forward drive and side-bite.
Replicated cuts helped turn the carcass into a low-profile tire giving it a racing stance like other successful JConcepts tires such as the Renegade. The tire includes 'React' open cell inserts which support the upper carcass and sidewall under loaded conditions. The tire carcass profile is light-weight and extremely low-profile giving the design of the tire just the right amount of contact patch for racing. Eyed by the experts as an excellent dirt tire, the Knobs may be used front or rear or paired with the Launch for ultimate tune-ability. The Knobs measure in at 5.80 x 4.0 x 2.6' and are available in two different compounds.
The soft 'blue' compound which is recommended for dirt, grass, and asphalt feels noticeably mushy and sticky and has expanding characteristics like off-road racings outdoor compounds. The 'gold' compound feels harder to the touch and excels on carpet, AstroTurf, and polished concrete surfaces and expands less during high speeds. The JConcepts tire has retro logo, tire name, sizing and tire part number identification bossed into the tire making it even more authentic.
Two tires are included (unmounted) per package and as always, the product is backed by JConcepts customer service, supported, and developed by professionals with style and authenticity.
