As more riders embrace the comfort and performance of wider tires, and with the widespread use of Tubeless Ready (TLR) tires, it has become more important than ever to make sure that the components used in the tire/rim system are compatible with each other. The ETRTO, or European Tire and Rim Technical Organization, is a standards organization that offers parameters ensuring compatibility, safety and performance of tires and rims, promoting uniformity in the industry. Challenge designs and manufactures tires according to these ETRTO recommendations. For quick reference we've created this page showing Rim Types, ETRTO Guidelines and all Challenge TLR models and our suggested combinations.

If you need clarification or advice about which tire is for you, always feel free to ask questions at info@challengetires.us
