Parts Unlimited Standard Tubes
Everyday inner tubes from Parts Unlimited, fit by tire size.
47 fitments · 11 wheel sizes · 47 in stock — from $8. Order online or install at MTC Orange County.
The Parts Unlimited Standard Tubes line covers 11 wheel sizes (8″–23″) across 47 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.
Valve stems in this family: JS244, PV78, TR4, TR87. 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.

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?
This family ships with JS244, PV78, TR4, TR87 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 Parts Unlimited 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 Parts Unlimited tube.
