The IRC T20056 Heavy-Duty Inner Tube is designed for dependable performance in demanding motorcycle, powersports, and off-road applications. Built to fit 18-inch tires that use a TR-4 valve configuration, this tube features a center-mounted metal valve for secure inflation and reliable service. Its heavy-duty construction provides added durability compared with standard tubes, making it a practical replacement for riders who need enhanced resistance to common trail and road hazards.
Manufactured by IRC and supplied under vendor part number T20056, this inner tube is made from resilient natural rubber.

Reinforced joint and valve areas further contribute to dependable fitment and long-term use when properly installed with a compatible 18-inch tire and rim.
Before installation, confirm that your tire requires an 18-inch tube with a TR-4 center metal valve. Inspect the tire and rim for debris, sharp objects, or damage that could cause premature tube failure, and follow the tire manufacturer’s recommended installation procedures.
