The mounting and demounting of tires should be undertaken only by a professional technician; improper hand- ding of the tire may cause irreparable damage that renders the tire unusable.
When replacing a tire, the installer must confirm the following:
• that the replacement tire is the correct size, as specified by the motorcycle manufacturer;
• that the speed rating and load index of the replacement tire are correct for the motorcycle;
• for certain motorcycles, the manufacturer specifies a particular brand and model of tire. Always refer to the owners manual or the tire manufacturer’s fitment guide for confirmation, or consult with a dealer that sells the brand of motorcycle in question. The valve stem should be replaced whenever a tire is installed, as the valve is essential to ensuring that the tire is airtight. It is illegal to ride on a public highway with slick tires or any other tires that are marked NHS (Not for High- way Service) or “FOR COMPETITION USE.”
