Overview

Dual-stage foam inserts for 1.9x4.19" (106mm tall) RC Crawler tyres. The firm inner closed cell foam and soft outer open cell foam work together to improve overall tyre performance. The soft outer foam allows the tyre to sink into the surface for more grip, while the firmer inner closed cell foam improves side hill performance and maintains a better sidewall structure. The firm inner foams are also more durable and longer lasting.
