Caliper – Caliper creates an exact width reading of your tires, making it a must-have tool for any bicycle enthusiast. This sliding ruler is equipped with jaws to ensure accuracy when measuring the diameter and thickness of bike tire walls.

Tape measure – To accurately calculate the width of your tire in millimeters, you can use a tape measure.

How to Measure a Bike Tire? Step by Step Guide

Determine the tire’s rim diameter

To find the tire’s rim diameter, place it on a flat surface and measure from one side of the rim to the other. It is important to use calipers when doing this as tape measures can be inaccurate.

Measure the bead width

The bead width is located at either side of the tire, just above where it meets with the rim. Utilize a caliper to measure the exact width of this section, and make sure that your readings are correct.

Check tire thickness

One of the most important measurements when it comes to bike tires is their thickness. Referring to the sidewall of the tire, find out its precise measure using a caliper or tape measure.

Determine the size of your wheel

The last step is to figure out the diameter and width of your wheel. Utilizing a tape measure, track these numbers from one side of the rim to the other for both its length and circumference.


Q: How do I know if my bike tire is the right size?

A: The best way to determine if your bike tire is the correct size is by measuring it with a caliper or tape measure. Make sure to check both the rim diameter, bead width, and thickness of your tire for accurate measurements.

Additionally, you should also measure the size of your wheel to ensure that the tire fits properly.

Q: How often should I check my bike tires?

A: It is generally recommended to check your bike tires every few weeks for wear and tear. Additionally, you should also take note of any changes in pressure due to temperature fluctuations or riding conditions.

Any time you notice a significant change in pressure, it is a good idea to check the tire measurements to make sure they are still accurate.

Q: What should I do if my bike tires don’t match the manufacturer’s specifications?

A: If your bike tires don’t match the manufacturer’s specifications, then you may need to replace them. It is important to ensure that your tires fit properly, as having an incorrect size can cause issues with your bike’s performance and even be dangerous.
