Key features

• •Experience quality with a pair of two TYK Industries 18x9.50-8 multi fitment lawn tractor tire inner tubes
• •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.
• •This is a multi-fitment inner tube that covers a range of sizes 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.
