Overview
IRC Heavy-Duty Tire Tubes
Some users contend that IRC Heavy-Duty tire tubes are the thickest tubes you can find for the price. All we know is, they are 3mm thick to resist punctures and pinch flats, a definite plus when you're competing in a race or scaling rough terrain miles from home. Made from a blend of natural and butyl rubber, IRC Heavy-Duty tire tubes meet or exceed OEM quality standards. Straight metal valve stems are bolted onto these rugged tubes, which are available in a full range of sizes to fit most motorcycles.
