With a 4.19-inch outer diameter and an asymmetrical profile, the design includes clear L and R markings for easy setup and consistent performance. The center tread uses a three-part layout: a solid center block that tapers toward the bottom with a break-away notch, plus a split center block on the opposite side to add flexibility on uneven terrain. The outer lugs zig and zag for bite, while recessed wear bars and staggered edges help balance traction across dry and rugged surfaces. Open-cell foam inserts accompany the tires, and the set is available in JConcepts sticky green compound for a controlled blend of grip and dampening on demanding trails.\u003c\/p\u003e\n  \u003cp\u003eDesigned to fit popular 1.9-inch bead-mount wheels, these tires work with plastic, aluminum, and steel wheel options. A continuous-thickness carcass helps maintain a clean profile, and the sidewalls feature wear-bar details to support tight climbs and rugged trails. Orientation is aided by left\/right markings for easy setup, and inserts are included to complete the ready-to-run crawling package.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"JConcepts (JCO)","offers":[{"title":"Default Title","offer_id":47991690625076,"sku":"JCO413802","price":27.75,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nankinhobby.com\/products\/rock-block-19-419-od-jco413802","provider":"Nankin Hobby","version":"1.0","type":"link"}
