Motorcycle Tyre Sizes Explained

By | September 1, 2023



As a motorcyclist, having the right tire size is essential. The wrong size can affect both performance and safety. To make sure you have the right tire size for your bike, it’s important to understand the different sizes available and how to read the numbers on the sidewall of the tire.

Tire sizes can be expressed in two different ways. The most common way is to use a series of numbers and letters. Motorcycle tires have three measurements that indicate their size: width, aspect ratio, and wheel diameter. The width is the distance from one sidewall to the other and is measured in millimeters. The aspect ratio is the height of the sidewall in relation to the width expressed as a percentage. Finally, the wheel diameter indicates the rim size in inches. Knowing these measurements allows you to determine the width and size of the tire. For example, a tire with a width of 110mm, an aspect ratio of 70%, and a wheel diameter of 17inches would be written as 110/70-17.

The second way to express tire size is by using the metric system. This method consists of three numbers, each preceded by a letter, such as 150/60R17. In this case, the letters represent the construction type of the tire, while the three numbers indicate the width, aspect ratio and wheel diameter.

It’s important to make sure you know the right size tire for your bike. By understanding the two different ways tire sizes are expressed, you can choose the right size for your bike’s needs. This will ensure that your motorcycle performs at its best and is safe to ride.
