Inner Tube Finder

Type your tire size to see the inner tubes and rim flaps we stock for it, with the valve on each one.

Find a Tube by Tire Size

Type the size molded on the tire sidewall. Most tubes fit a range of sizes, and each listing shows them all.

Valve

Match the valve to your rim's valve hole and how you fill the tire.

Type a size or tap an example.

Reading the Size

A small tire labeled 16 by 6.50 dash 8: height, width and rim diameter 16 8 rim 16x6.50-8 6.50 wide

Height x width - rim

Mower, ATV and flotation sizes like 16x6.50-8. The last number is the rim diameter in inches.

A tractor tire labeled 11.2 dash 24: section width and rim diameter 11.2-24 11.2 in wide 24 in rim

Width - rim

Farm, truck and industrial sizes like 11.2-24 or 7.50-16. An R in place of the dash means radial.

A dual size marking 4.80 slash 4.00 dash 8 meaning either size fits 4.80/4.00-8 two sizes, same rim

Dual sizes

4.80/4.00-8 covers both 4.80-8 and 4.00-8 on an 8 in rim. The finder matches either one.

Choosing the Valve

Straight rubber tube valve

Straight rubber

Rubber covered stem for passenger, trailer, mower and ATV tubes.

Straight metal tube valve with a rubber base

Straight metal

Metal stem on a rubber base, common on truck and farm tubes.

Bent metal tube valve

Bent metal

An angled stem for wheels where a straight one won't reach or clear, as on many truck wheels.

Large bore air and water valve for liquid filled tractor tubes

Air/water

Large bore valve, like the TR218A, for tractor tubes that hold liquid ballast. Fill and drain through it.

Installing a Tube

  • Use a tube made for the tire's size range. Never use a tube to stop a leak in a tubeless wheel.
  • Dust the tube with tire talc (a dry lubricant), and use an approved liquid lubricant on the tire beads and rim.
  • Seat the beads on a locked down tire machine or in a safety cage, and never go over 40 psi to seat them unless the tire maker allows more.
  • Once the beads seat, let all the air out and re-inflate. That lets the tube settle without folds or creases.
