Mitas Ultra Heavy Duty Tubes
Ultra heavy-duty inner tubes from Mitas, fit by tire size.
3 fitments · 3 wheel sizes — from $22. Order online or install at MTC Orange County.
The Mitas Ultra Heavy Duty Tubes line covers 3 wheel sizes (18″–21″) across 3 fitments — for dual-sports, adventure bikes, and vintage iron, adventure and dirt bike fronts. The thickest-wall build for the hardest use — extreme off-road, racing, and heavy loads where a standard tube would pinch or overheat. Mitas states the wall thickness on this line: 4mm.
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: TR6. 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.

What is an ultra heavy-duty tube for?
The thickest wall available — built for extreme off-road, racing, and heavy loads at very low pressure. Overkill for the street, essential when you're pushing a tire to its limits in the dirt.
How do I know which valve stem I need?
This family ships with TR6 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 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.
