2-stage foams for 4.45" RC crawler tires. They are two stage foams, outside is open cell and inside is closed memory cell.
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.
