Hey Guys,

Basically you just slot in your Tread width/Profile/Diameter and compare with the Tire Specs you want to get! It will tell you if it falls within the 3% diameter height of the original tire.

It is recommended staying within the 3% as if you go any higher you face the risk of brake failure.
