Although not meant to serve as a replacement to air, in the event of a puncture, the blocks are firm enough to allow the tire to continue operating as though it were fully inflated. The blocks themselves are custom cut, high-density foam inserts that remove all of the dead space inside the tire. Tire Blocks, the newest name in run flat technology to hit the market, seems to be on to something. Some work better than others, but most are just a temporary fix, add significant weight or cause a change in the performance or handling of the vehicle.Ī true run flat solution that allows the tire to continue performing as if it had air in it, without affecting the handling of the vehicle or adding significant weight, is a tall order. Over the years there have been many run flat systems that attempted to solve this problem with inflatable inserts, foam inserts or even slimy goo that supposedly plugs the whole and patches the tire. Racer or not, flat tires are something every off-roader has deal with at some point in time. Peace of mind for racers and trail riders alike
