Important Notes

Upon delivery, the tire will arrive in a folded configuration to facilitate shipping and packaging. To ensure proper shape and optimal performance, allow the tire to rest unfolded and laid flat for one to two days before installation. This crucial step helps restore its intended profile and prevents deformation during use, ensuring you get the full performance benefits of the tire’s design.

Please verify your bike’s specifications and required dimensions carefully before making your purchase decision. Only one tire is included in the package—no wheel rims or additional components are provided. Confirm fitment with your vehicle model to avoid compatibility issues and ensure proper installation. Always check manufacturer guidelines and safety recommendations when replacing tires on any vehicle type.
