(2 Pack) TYK Industries 8.5L15, 9.5L15 Heavy Duty Inner Tubes for Farm Tractor Implement Tires with TR13 Short Rubber Valve Stems.

8.5L15 WITH TR13 VALVE STEM. The 8.5L15, 9.5L15 Tube with TR13 valve stem is a multi-fitment, ultra high quality inner tube that covers a range of industrial vehicles and trailers.
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.
DURABLE VALVE PERFORMS BETTER. Our superior vulcanization process creates a strong seal around the TR13 valve stem. Plus, the valve lock nut adds protection and allows you to run lower air pressures for better tire grip.
FITS MOST 15″ WHEELS. These inner tubes are compatible with many light truck tires, farm tractor tires, trailers, and other implements with 15 inch rims.
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.
