This is a set of Extra Wide cell foam inserts for 4.45" tires. They are made for Boom Racing´s extra wide ProBuild and KRAIT wheels.
Dual-stage foam inserts for 1.9x4.45" (113mm tall) RC Crawler tires.
Soft outer foams help the tires conform to the surface. A firmer inner closed-cell improves sidehill performance and maintains a better sidewall structure. They are more durable and longer-lasting.
