• Experience quality with a pair of two TYK Industries 18x8.50-8 multi fitment lawn tractor and ATV tire inner tubes for bias or radial tires. HEAVY DUTY INNER TUBES. 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. The off-set straight metal TR6 valve stem with lock nuts adds protection and allows you to run lower air pressures for better grip on the trail. 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.
