MITAS Heavy Duty Tube
Heavy Duty inner tubes from MITAS, fit by tire size.
12 fitments · 8 wheel sizes · 10 in stock — from $11. Order online or install at MTC Orange County.
The MITAS Heavy Duty Tube line covers 8 wheel sizes (10″–21″) across 12 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. 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.
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?
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 MITAS 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 MITAS tube.
