The Black Jackets from JConcepts made their successful debut at the Dirt Nitro Challenge and Neo Buggy events during the 2012 racing season. The Black Jackets, constructed from very small square pins, provide additional grip on loose conditions with a light amount of dust and debris across the surface. The tread spacing near the outside rows are slightly open allowing maximum flexibility to adhere to smooth and slick surfaces providing a reasonable flex contact patch. The crisp centre bar construction provides a wall-like pattern of tread which provides additional forward bite and also resists some high-expansion wear associated with typical small pin tyres.
The Black Jackets have a quick and nimble feel on the track which translates into quicker lap-times for the driver in certain conditions. The small pin construction made them ideal for the bumpy conditions while the centre bar support allowed plenty of forward traction to climb up to a top spot on the podium. The Black Jackets inner ribbing features a repeated X-type ribbing which reduces the amount of tyre expansion under power while still being soft and cushy for bumps and rutted sections. The new high-performance tyre includes JConcepts “Force-1” inserts.
The second tyre announced is the Stacker which is a culmination of successful DNA from the highly popular Hybrids and Crowbars tyre tread patterns. The Stacker reveals a heavy centre lug design which are supported at the lower base with extra rib features and tiny fillets which provide a heavy forward gripping force. Directional slashes cut into the tread soften the lugs to absorb bumps and also increase the lug flexibility to accommodate loose conditions.
The outer rows are a medium to hefty size lug with alternating positioning to drive forward and side-bite while the stacked rows actively react with one another to lower the overall wear of the tyre. The side-lugs are finished off with a hard angle to ease the transition from forward to side-bite while maintaining a linear feel without edginess in the turns. The Stacker inner ribbing features a repeated X-type ribbing which reduces the amount of tyre expansion under power while still being soft and cushy for bumps and rutted sections. The Stackers include JConcepts “Force-1” inserts to finish off an extraordinary tyre.
