Tyre Size Conversion - mm to inches


Tyre Size Conversion
Tyre size conversion from metric to inche is very confusing and can not be done by simple conversion from MM to Inch. please use the table below to find out equivalent size. the major difference is that tyres with metric size are generally low profile tyres and Inch system was used earlier when tyres had square profile i.e. aspect ratio of 100%. Approximate equivalent tyre sizes are mentioned below

Disclaimer:

The above tire size conversion chart does not mean that these tires are universally interchangeable. They are to give you a point of reference when upgrading your older tires. Consult your motorcycle's manual or manufacturer's customer service department for correct replacements for original equipment tires.
Critical clearances, motorcycle compatibility and stability, load-bearing capacity, speed rating, radial vs. non-radial, pattern and tread compound requirements, inflation recommendations, and front-to-rear tire matching will all vary with tire selection.

Wrong selection can result in tire failure, loss of control with serious injury or death. You can also contact the manufacturer of the tires you want to put on your bike. They have reps dedicated to this stuff.
