Description

The JConcepts Rock Bumps is a pin-style crawler tyre engineered for 1.0” mini comp crawler competition. With a 63mm overall diameter for ground clearance and a narrow carcass to increase contact pressure, the tread combines hefty pins with horizontal and vertical connector bars to flex, pivot and conform across varied terrain. Molded in JConcepts’ sticky green compound and supplied with React open cell inserts, this SCH-JC4128-02 tyre focuses on reliable traction, sidewall support and consistent performance.

A large central lug initiates forward drive, while relief cuts and angular edge bars transition into an open sidewall shield, keeping fresh biting edges available as the tyre loads up. Elaborate radial ribs and additional sidewall bars aid anti-slip characteristics and outside carcass thickening, finished with authentic JConcepts lettering and sizing details.

Specifications

When it comes to competition, it’s hard to beat a pin style tire. JConcepts introduces the Rock Bumps tires specifically designed for 1.0” mini comp crawler competition. The name suggests similarities to a popular dirt and all-terrain tire used for years in the #gojconcepts line-up, the Goose Bumps. The hefty surface area of the pins, combined with horizontal and vertical connector bars bridge together walls of grip to flex, pivot, and conform to just about any terrain.

The large size overall diameter of 63mm provide ample ground clearance, and the narrow contact patch area increases the pressure applied to each pin to provide jumbo patterns of traction. The center of the tire features a large lug to get the heavy lifting started; the relief edges provide clearance to the next closest pins. Angular traction bars on the edges start the sidewall started and transition to an open shield feature to keep surface area edges present in the design.

The narrow tire carcass, with continuous contour, has major flex characteristics providing even greater conformity to rocks, holes, bumps, and just about anything in its path. Elaborate radial ribs and an array of additional bars on the sidewall of the tire aid in anti-slip, and outside carcass thickening. Embossed JConcepts logos, item name, part number, and sizing help identify the performance item and heritage of the design.

Molded in the exclusive JConcepts sticky green compound, the Rock Bumps tires include React open cell inserts that have a medium feel and fills the tire appropriately to conditions. The JConcepts tires are packaged, and tagged with holographic decal on the rear of the packaging to help customers identify authentic products. The JConcepts team builds, tests, and travels the world to support the brand and gathers valuable driver feedback in search of the best appearing and performance items on the market.

The product is designed in the U.S.A. and always backed by JConcepts customer service, supported, and developed by professionals with style. Look for reputable dealers and distributors and demand authentic products – choose JConcepts
