When David Ronnefalk joined the JConcepts Racing team, he had a recommendation. “Let’s develop a tire for the Euro drivers where the tracks are more dry, rutted and dusty.” The team set off on a mission by evaluating JC’s past and present tread patterns to arrive at a new build. Tires such as the Hybrid, Chasers and Stackers, already in the line-up, have all served well and have won major events; however, Kosmos has it all.
Starting with a clean shape and carcass, the design team took to a rectangular based pin which has the forward bite muscle to boost a 1/8th buggy. The staggered rows create a unique zig/zag affect at certain views giving it a 3D mind puzzle affect. In fact, the design is 4 rows deep of off-set and staggered sections when compared to some traditional tires which rely on 2.
JConcepts has connected several sections of pins with a V-feature to strengthen the base to make Super Soft compounds manageable even in high-speed conditions. The outer rows of pins have been clipped and held back for maximum cornering consistency on bumpy and chunky conditions. The inside of the carcass boasts the standard 3 radial ribs that help minimize tire expansion under hard acceleration and cushions hard impacts.
The JConcepts tires include the Dirt-Tech closed cell inserts made famous by their gray color and durability. The package is complete with re-sealable, zip-top packaging and backed with JConcepts customer support and racing heritage.
