Composite Rubber RunFlat (CRRF) - a specially designed composite runflat with a rubberized crown to provide mobility for the off-road vehicles equipped with tubeless tires and standard one-piece drop-center wheels.

These specialized runflats are similar in design to the standard CRF’s, but the addition of the rubber provides sufficient compliance when traveling across open terrain in the runflat mode to improve the ride and reduce vibrations and bumps transmitted to the vehicle and crew.
