If you can’t any information on the tire tag but you want to know the tire size ,what will you
do ? When you are in this condition,taking a measurement to determine the size is almost as
easy and requires only a few minutes.

Step 1
Look along the outside of the tire wall. The tire size and recommended inflation pressure
usually are stamped into the rubber there. If you can find this and it hasn't been obscured
by damage or wear, skip the remaining steps.
Step 2
Put the bicycle in a stable position. You can put it on a stand, drop the kickstand or lean it
against a wall. Just make sure it won't fall on you while you are working .
Step 3
Check the tire's inflation. Pinch the tire with your thumb or use a pressure gauge. The latter
will be helpful only if you know the recommended inflation pressure. If the tire is flat or almost
flat, inflate it. Tire measurements are divided by increments of 2 or 4 inches, so the only way
inflation will distort the measurement is if the tire is empty or almost so.
Step 4
Measure the tire. Place the tab or end of your tape measure under the bottom of the tire and
extend it to the top of the tire. The tire size is the diameter of the tire from its outside edges.
Slightly improper inflation can affect the measure, but not enough to prevent you from taking
a measurement that can be rounded off. For example, a 23.66inch measurement is obviously
a 24-inch tire, and not a 20-inch tire overinflated to the point of exploding.
Step 5
Determine the width of the tire using the tape measure. This is usually unnecessary, but sometimes
that figure is needed for specialty tires with unusual sizes.
