A word from Piet @ the Wolfpit.

Ere will adhere to the new 2020 ETRTO sizing rules, and all our new tires and wheel/rim models will follow the below sizing chart to conform with the international ETRTO standards, so check your wheels and tires when you are up to replacing them, it's good the know and understand that the combination of the product your are about to buy is compatible in terms of sizing.
