IRC Standard Tubes
Everyday inner tubes from IRC, fit by tire size.
15 fitments · 7 wheel sizes · 14 in stock — from $9. Order online or install at MTC Orange County.
The IRC Standard Tubes line covers 7 wheel sizes (10″–23″) across 15 fitments — for scooters and small-wheel machines, cruisers, baggers, and touring bikes, spoked sport and standard bikes, dual-sports, adventure bikes, and vintage iron, adventure and dirt bike fronts. Standard-wall construction for everyday street and light-duty riding — the right call for most on-road spoked wheels.
Find your fitment by the size printed on your tire sidewall (for example, a 90/100-18), pick the matching tube, and order it shipped or install it at MTC. Spoked wheels need a tube; if you're unsure, we'll confirm the right one.
Is a standard tube good enough for my bike?
For street riding at normal pressures, yes — a standard-wall tube is the right tube for most on-road spoked wheels. If you carry heavy loads or ride off-road at low pressure, step up to a heavy-duty tube.
How do I know which valve stem I need?
Most fitments use a straight TR4 rubber stem; some use TR6 or a metal (JS) stem to clear the wheel. The valve type is noted on each size below — match it to your wheel, or ask us.
Does MTC install IRC tubes?
Yes — we mount and balance your tire and tube in-shop, or ship the tube to your door. Call (714) 516-9059 with your tire size and we'll pull the exact IRC tube.
