WARNING: Re-assembly of mismatched parts can result in serious injury or death. Just because parts fit together does not mean that they belong together. Check for proper matching of all rim parts before assembly. Mismatching tyre and rim components is dangerous. A mismatched tyre and rim assembly may explode and can result in serious injury or death. This warning applies to any combination of mismatched components and rim combinations. Never assemble a tyre and rim unless you have positively identified and correctly matched the parts.
