Want to know more about your tires?

Here is a simple guide to unlocking the information on the sidewall of you motorcycle tires.

You will see a series of numbers on your sidewall i.e. 130/90HB-16 What these numbers stand for is the tire width, aspect ratio, speed rating, construction type and rim diameter. For instance, the 130 stands for 130mm of tread width.

The 90 stands for the aspect ratio (sidewall height) which is a percentage, so for a 130/90 the aspect ratio/sidewall is 90% of the tread width or 117mm.

The next number (speed rating) determines what speed, that this tire is designed to be safely operated. In this example, the H speed rating means that tire has a maximum speed rating of 130 MPH. V-rated tires have a maximum speed rating of 149MPH and Z-rated is 149+MPH. This doesnít mean it is ok to break the speed limit, it simply means the manufacturer has certified that tire to be capable of those speeds.

The Next letter designation stands for the construction of the tire itself. In this example, the B stands for Bias construction, meaning the tire is a bias ply, not a radial. You will see an R in this place if the tire is of radial construction.

Last but not least is the rim diameter. You canít fit a 16" tire on a 18" rim, so itís important to you to know what size rim your dealing with when replacing tires.
