Premium Tractor Tire Inner Tube | 11.2-36, 12.4-36, 13.6-36, 13.9-36 | TR218 Heavy Duty Liquid/Air Valve

Heavy-Duty Reliability for Demanding Agricultural Applications

Restore your agricultural performance with our premium-grade rear tractor tire inner tube. Engineered from high-density, thick-walled butyl rubber, this heavy-duty inner tube is specifically designed to handle the extreme torque, heavy loads, and punishing field environments faced by modern farm tractors and industrial equipment.

Equipped with the industry-standard TR218 valve stem assembly, this tube easily supports both traditional air filling and liquid ballast hydro-inflation (calcium chloride/water) to add crucial traction-building weight to your rear axle.
