About the Razor Wire 1.9" Tires
Razor-Inspired Tread Geometry
The razor-inspired tread pattern combines interlocking center lugs, aggressive shoulder blocks, and strategically placed siping to maximize traction without sacrificing steering precision. Angular tread blocks create multiple biting edges for confident grip on challenging terrain, while the connected center tread maintains a consistent contact patch for smooth, predictable control. Large shoulder lugs wrap onto the sidewall to improve side bite during off-camber climbs and sidehills, helping the tires stay planted when the terrain gets technical.
Siped for Maximum Grip
Deep siping allows each tread block to flex and conform to uneven rock surfaces for increased traction and control. This added flexibility helps the tire maintain contact across rough obstacles, improving stability and confidence while crawling at low speeds. Whether navigating rocky trails, loose dirt, or mixed terrain, the Razor Wire delivers the grip needed to find the best line.

So far so good! Great compound for technical crawling. Pretty thin just fyi. They’re also a bit fatter than other like Proline Swampers and Krawlers so inserts like the injora ones don’t quite fill them up. The stick foams are soft though. I recommend.
Compound is great and traction is great but would not buy again sidewalls have holes/tears because how thin the tire is there.
