Our tire tubes are up to 4X thicker than the competition. Thicker, high-quality butyl rubber prevents air from penetrating the inner tube for longer-lasting inflation, and it provides better protection from punctures and leaks.. BUILT FOR DURABILITY. TYK Industries’ products contain a thicker butyl rubber material to help prevent decay, and our superior vulcanization process creates a strong seal around the valve stem. Plus, the upgraded valve performs better than other tubes.. FITS MANY WHEELS. Besides lawn mowers and yard tractors, these inner tubes are also compatible with many wheelbarrows, dollies, trolleys, garden wagons, generators, air compressors, go carts, ATVs, and quad bikes.. THREE YEAR WARRANTY. TYK Industries inner tubes come with a 3-year warranty that covers manufacturing and workmanship defects. Each tube is test-inflated at the factory before boxing, so you can be assured of a successful installation every time.
