Tire Replacement
Periodically, it will be necessary to replace a flat or worn tire. If replacing a worn or flat tire, make certain the new tire meets your vehicle manufacturer's size and performance (speed) specifications found on the tire placard. In general, replacement tires should always be of the same size and performance specification as recommended by the vehicle manufacturer.
Special equipment is required to dismount the old tire from the wheel and correctly mount the new tire on the wheel. Furthermore, all new tire/wheel assemblies must be balanced. If the tire is not in dynamic balance, it will shimmy at highway speeds. If it is not in static balance, it will bounce up and down. Dynamic balance includes, and is better than, static balance.
Improperly mounted tires can explode when inflated. Because of the inherent dangers, replacing a tire on a rim must only be done by a professional automotive technician. When buying a new tire, register your name with the tire manufacturer or tire dealer so you can be contacted if necessary.
