Dual-stage foam inserts for 1.9x4.75" (120mm tall) RC Crawler tires. They are firm inner closed cell foams and soft outer open cell foam.
Soft outer foam provides traction for the tire to sink into the surface for more grip. A firmer inner closed cell improves sidehill performance and maintains a better sidewall structure. The firm inner foams are more durable and longer lasting.
