18x8.50-8 TUBE WITH TR13 VALVE STEM. The 18x8.50-8 Tube with TR13 valve stem is a multi-fitment, ultra high quality inner tube that is made to be used in the following sizes: 18x8.50-8, 18x9.50-8, 20x8.00-8, 20x8.50-8, 20x9.00-8 and 20x10.00-8.
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 TR13 short rubber valve stem is commonly found on passenger, light truck, front tractor, lawn tractor and small industrial tire tubes. This valve stem is a straight rubber stem that is 1.38 inches long and designed to be used in a 0.453 inch rim hole.
FITS MANY WHEELS. This is a multi-fitment inner tube that covers ATVs, UTVs, Golf Carts, and other small vehicle due to the elastic and durable properties of today's butyl rubber.
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.
