How to Read Tire Tube Sizes

Tire tube sizes are usually printed on the tire sidewall in a format like this:

15×6.00-6 or 20×10.00-8.

Here’s what it means:

  • 15 = Overall tire diameter (in inches)
  • 6.00 = Tire width
  • 6 = Rim diameter

So a 15×6.00-6 tire requires a tube that fits a 6-inch rim and 15-inch outer diameter.

Tips for Replacing Lawn Mower Inner Tubes

If you’re planning to replace or install new tire tubes, here are a few helpful tips:

Check the Tire and Rim First

Before buying a new tube, inspect the tire for cracks, dry rot, or punctures. Also, check the rim for rust or sharp edges that might damage the new tube.

Use Soapy Water

Lubricate the tire bead and tube with soapy water to make installation easier and prevent pinching the tube.

Don’t Overinflate

Follow the PSI rating stamped on your tire. Overinflating can cause the tube to burst or distort.

Match the Valve Stem

Some tubes come with straight valve stems, while others are bent. Make sure to match your old one to ensure easy access and clearance.

Tube vs. Tubeless Tires

Many modern lawn mower tires are tubeless. So, when do you actually need a tube?

You need an inner tube if:

  • The tire won’t seal to the rim properly
  • The rim has rust or damage
  • The tire has slow leaks even when sealed
  • You’re trying to repair a tubeless tire temporarily

FAQs

How do I know what size tire tube I need?

To find the correct tire tube size, check the size printed on the sidewall of your tire. It will look something like this: 20×10.00-8. This number tells you the dimensions of the tire and what size tube is compatible.

Once you know your tire size, choose a tube that matches both the tire size and rim diameter.

For example, a tube labeled 20×10.00-8 fits a 20″ diameter, 10″ width tire mounted on an 8″ rim.

If your tire is worn out and the size marking is not visible, you can:

  • Look up your mower model in the owner’s manual.
  • Measure the diameter, width, and rim size manually with a tape measure.

How do you read a lawn mower tire tube size?

Tube sizes are read in the same format as tire sizes, typically written like:

  • 15×6.00-6
  • 20×10.00-8
  • 16×6.50-8

This means:

  • First number (20) = Overall diameter of the tire (in inches)
  • Second number (10.00) = Tire width (in inches)
  • The third number (8) = Rim diameter the tire fits on

So a 20×10.00-8 tube fits tires that are 20 inches in diameter, 10 inches wide and mounted on an 8-inch rim.

How do I know what size lawn mower tire I need?

To determine the correct lawn mower tire size:

  1. Check the sidewall of your current tire – You’ll see something like 15×6.00-6 printed on it.
  2. Use your mower’s manual – It will list OEM tire sizes.
  3. Look online for your mower model – Manufacturer websites often provide tire specs.
  4. Measure it manually:
    • Diameter (from edge to edge across the tire)
    • Width (across the tread)
    • Rim diameter (across the inside edge of the rim)

What does 20×10-8 mean on a tire?

This is a common lawn mower tire size. It breaks down as:

  • 20 = Tire height (outer diameter) in inches
  • 10 = Tire width in inches
  • 8 = Rim diameter in inches

So, this tire is 20 inches tall, 10 inches wide, and fits an 8-inch rim.

How do you match a tire tube?

To match a tire tube:

  1. Match the tube size to the tire size exactly or within the size range listed (some tubes fit multiple sizes).
  2. Make sure the valve stem style fits your rim and is accessible.
  3. Use the same rim diameter as the tire and wheel (e.g., an 8-inch tire must use an 8-inch tube).
  4. Buy tubes labeled as compatible with your tire size, like “fits 20×10.00-8.”

Example: If your tire says 20×10.00-8, choose a tube that either exactly matches or is labeled as fitting 20×10.00-8.

How do I check my tire size?

There are 3 simple ways:

  1. Look at the tire sidewall – You’ll find a number like 15×6.00-6 molded into the rubber.
  2. Consult your mower’s user manual – It lists factory tire sizes.
  3. Physically measure the tire if the marking is worn off:
    • Use a tape measure to find the overall height, width, and rim diameter.
Tip: Always double-check all 3 measurements before buying a replacement tire or tube to ensure a proper fit.
