JConcepts unloads a new crawling tire option to market with Rock Block. An all-condition performer, the Adventure Team from Groveland, Florida has incorporated many new details in these 4.75" beauties. The asymmetrical design allows the driver to set up the tire to their individual liking but is conveniently marked with L & R denotation. A center structure sits as a multi-faceted combination of 3 tread lot elements. The solid tread block falls away and draws a little more size toward the bottom and includes a small break-away notch and top tread recess.
On the other half of the center line, the split block offers more flexibility and contortion for difficult and uneven terrainch It balances nicely sitting next to its solid counterpart and together and share the burden of competition climbs or day to day trail running business. On the outside, the lugs zig and zag to compliment the center support and include top recess to add additional edges for dry course grip. In-between the outer bars, low height wear bars are applied to tie-in sidewall detail. Clipped edges and staggered formations help offset low and high grip sections of land.
Momentum based sidewall attributes have a progression pattern consistent with forward direction. The main ingredient in the sidewall, the low height wear bar ribs connect everything together to help function as a single until during tight climbs and narrow spaces. Recessed cuts in the blocks, extrusions in timely areas help detail out one of the most sophisticated crawling tires in the JConcepts line-up. Recessed JConcepts logo with inner hatching takes position in multiple areas while the tire name, part number 4054 L/R is marked for easy identification.
The Rock Block tire includes "open cell" foam inserts to support the ride and packaged and sealed with authentic JConcepts packaging with hologr
