With an outer diameter of 4.75\" and an asymmetrical pattern, Rock Block is perfect for Class 2 trucks and technical terrain where every little contact point counts.\u003c\/p\u003e\n\u003cp\u003eThe tire is designed by the JConcepts Adventure Team in Groveland, Florida, and combines a sophisticated pattern, well-thought-out sidewall construction, and the legendary “sticky green” rubber compound – all to give you a tire that works equally well for competition crawling and serious trail driving.\u003c\/p\u003e\n\u003cp\u003e—\u003c\/p\u003e\n\u003cp\u003eAsymmetrical pattern – tune the grip to your driving style\u003cbr\u003eRock Block is built with an asymmetrical pattern so you can mount the tires exactly how you want:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEach tire is clearly marked with L (Left) and R (Right) on the sidewall\u003c\/li\u003e\n\u003cli\u003eAllows you to optimize traction and side bite according to your setup\u003c\/li\u003e\n\u003cli\u003eIdeal for both front and rear axle, where you want to control how the tire behaves in corners and on sidehills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe asymmetrical design makes it easy to fine-tune the vehicle to your specific driving environment – from smooth rock to loose forest floor.\u003c\/p\u003e\n\u003cp\u003e—\u003c\/p\u003e\n\u003cp\u003eAdvanced center section – combination of three tread types\u003cbr\u003eThe center of the tire is built as a multi-faceted 3-tread-element structure that provides both stability and flexibility:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSolid center block that “drops” slightly downward and becomes a bit wider toward the base\u003c\/li\u003e\n\u003cli\u003eSmall break-away notch and top recess in the block for extra edges and controlled deformation\u003c\/li\u003e\n\u003cli\u003eOn the other half of the centerline: a split block that provides more flexibility and contouring over uneven terrain\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe solid and split blocks work together and share the load on steep climbs, sidehills, and technical sections.

grip where you need it most\u003cbr\u003eOn the outer part of the tire you’ll find a zig-zag pattern that supports the center structure:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOuter lugs in a zig-zag shape that help with side grip on sidehills and in corners\u003c\/li\u003e\n\u003cli\u003eTop recess in the lugs creates extra sharp edges for traction on dry and hard surfaces\u003c\/li\u003e\n\u003cli\u003eBetween the outer ribs there are low wear bars that tie the pattern and sidewall together\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe chamfered edges and staggered formations are designed to handle both high- and low-traction sections so the tire doesn’t suddenly let go, but instead provides a more predictable transition when the surface changes.\u003c\/p\u003e\n\u003cp\u003e—\u003c\/p\u003e\n\u003cp\u003eSidewall focused on control and stability\u003cbr\u003eThe sidewall on the Rock Block is just as well thought out as the tread itself:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMomentum-based pattern that follows the direction of travel for better forward stability\u003c\/li\u003e\n\u003cli\u003eLow wear bar ribs that connect sidewall lugs and help the tire work as one cohesive unit under heavy side loads\u003c\/li\u003e\n\u003cli\u003eExtra recessed cuts and small extrusions in blocks and sidewall to provide more micro contact points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis combination makes the tire more stable on steep sidehills, narrow passages, and when you wedge the tire between rocks and edges.\u003c\/p\u003e\n\u003cp\u003e—\u003c\/p\u003e\n\u003cp\u003eSticky Green Compound – max grip for crawling\u003cbr\u003eRock Block comes in JConcepts’ popular “sticky green” compound – a soft

mechanical grip\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis compound is an obvious choice for both competition and serious hobby use, where you want a tire that bites even when things get
