IRC Heavy Duty Tubes
Heavy Duty inner tubes from IRC, fit by tire size.
10 fitments · 6 wheel sizes · 10 in stock — from $12. Order online or install at MTC Orange County.
The IRC Heavy Duty Tubes line covers 6 wheel sizes (10″–19″) across 10 fitments — for scooters and small-wheel machines, cruisers, baggers, and touring bikes, spoked sport and standard bikes, dual-sports, adventure bikes, and vintage iron. Thick-wall heavy-duty construction that resists pinch flats under load and at the low pressures off-road riding demands.
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.
Valve stems in this family: TR4. The stem has to clear your wheel, so match the code on the fitment you pick.

Tube-type (spoked-wheel) tires we stock in sizes this family covers. Check your wheel — a cast wheel runs the same size tubeless and needs no tube.

Do I need a heavy-duty tube?
If you air down for dirt, carry a passenger or gear, or run a heavy bike, yes — the thicker wall resists pinch flats and heat that thin tubes suffer under load. For street-only riding, a standard tube is fine.
How do I know which valve stem I need?
This family ships with TR4 stems, and the exact code is listed against every fitment in the table above. The stem must line up with the hole in your rim and clear the brake/sprocket side, so match the code on the tube to the one that came out of your wheel — or bring the wheel in and we'll check it.
Which tire sizes does one of these tubes cover?
Each row in the table above lists the manufacturer's own fitment range verbatim — many tubes cover several tire sizes on the same wheel diameter (for example a 3.25/4.10 tube fits both of those widths on its rim). Pick the row whose range includes the size printed on your sidewall.
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.
