TYK Industries' 16.9/18.4R38 inner tube is a multi-fitment, ultra high quality inner tube that works with both radial and bias ply rear farm tires. Our inner 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 provides better protection from punctures and leaks. TYK Industries’ tubes are manufactured from a thicker butyl rubber sheet to fight ozone and weather cracking, and our superior vulcanization process creates a strong seal around the valve stem. Plus, the quick flow valve stem performs better than other tubes. Our multi-fit tube is made to be used in the following sizes: 16.9-38, 18.4-38, 420/85R38, 460/85R38 and 480/80R38. TYK Industries inner tubes come with a 3-year warranty that covers manufacturing and workmanship defects. Each tube is inflation tested at the factory before boxing, so you can be assured of a successful installation every time.
