The JConcepts Adventure team dug deep and looked at the tire line-up for simple yet performing solutions for an existing item in the line-up. The Scorpios, one of the original crawling tires from the team, has been a favorite for year, but after a nudge from the development team has undergone some changes. A new ground up item has all the functions, features, and specialty construction as the original but by removing some elements is pushing the limits once again.

Introducing Rock Scorpions, a scale looking tread with tall size and profile, jump out as the most obvious features. Starting by analyzing the tread, the design team focused on adding a bit more space for grabbing patches and edges. The padded arrangement of tread makes the tire ideal for transitioning from sand to dirt, and into slightly wet terrain, the Rock Scorpions can do it all. The rather scale-looking tire has some dramatic zig-zag action and with minor relief cuts, contour to very rugged conditions.

The traditional 1.9” mounting bead diameter is ready for just about any wheel in performance-oriented builds, and the 1.5” width is now a new trend setting design element by JConcepts. Each tread block has finely cut edges with a healthy radius where the block meets the tire body. The outermost lug extends down the sidewall to stiffen the upper carcass and increase the pinch grip. The flexibility of the compound combined with inner grid ribbing provides support to a purpose-built performance core.

The large overall height provides plenty of ground clearance for an abundance of terrain and sidewall tire lettering featuring brand, type, and sizing help identify a winner. The tires include a soft open-cell foam insert capable of standing up to the super soft compound but flexible enough for sharp terrain. Prepare your rig for competition with Rock Scorpions from JConcepts.

The Ruptures tire has helped the Adventure Team from Groveland, Florida ascend to great heights on and off the course with its technical nature, outrageous detail, and burly tread. The super soft green compound grips like a monster, while the tall (121mm | 4.75”) profile tackles terrain adding important ground clearance. The performance tire has a new wrinkle, now designed for 2.2” wheels, the sidewalls are a bit shorter than previous generations adding new responsiveness.

The Ruptures are an extremely tacky tire, and with the large islands of tread, the blocks stand up to even the most difficult climbing obstacles. Individual plots of surface area pack this design, but it’s the strategic cuts that provide flexibility and open edges to constantly perform at a high-level. The soft and gummy candy like feel comes natural courtesy of the exclusive JConcepts compound. Solid sidewall detail is braced for high impact resistance, and the center mini plots of tread lend a helping hand when the rig is in a bind.

The recessed nature of the tread gives the Ruptures tire options like no other. Dirt and debris can load up in one direction and clean out in the other due to flex, rotational drive, and the multitude of recessed levels. There is always a fresh edge, a wall, or tread plane that helps lift a vehicle out of dangerous situation. A radial rib on the sidewall connected to a double ended arrow helps the JConcepts tire stand-out from copies and sampled items on the open market.

The JConcepts trending 1.5” narrow carcass is extremely pliable which conforms to many obstacles and helps apply pin pressure. Inside the carcass, JConcepts features a connected “Y” loop ribbing design which blends carefully into the sidewall. The bracing supports the lower half of the tire while maintaining the upper flex characteristics. The tires include a soft open-cell foam insert capable of standing up to the super soft compound but flexible enough for sharp terrain.
