How much air should I put in my tires?

It is always recommended to use the pressures advised by your motorcycle manufacturer. These can be find in the motorcycle handbook and the tire specfication section.

Why do tires lose pressure in cold weather?

In cold weather, tire pressure drops because the air inside contracts, so it’s important to check and maintain proper pressure for safety and performance.

What do the numbers on tires mean?

The numbers on a motorcycle tire show key details like its size, fit, and performance ratings, including width, aspect ratio, rim size, load capacity, and speed rating.

Do motorcycle tires need to be balanced?

An unbalanced motorcycle tire can cause vibrations, uneven wear, and reduced stability, so proper balancing is important for a smoother, safer ride and longer tire life.
