Tire Care and Maintenance Punctured Tires Replacing Tires and Wheels A puncture eventually causes the tire to lose Tires degrade over time due to the effects of pressure, which is why it is important to check ultraviolet light, extreme temperatures, high tire pressures frequently. Permanently repair loads, and environmental conditions. It is or replace punctured or damaged tires as recommended that tires are replaced every six soon as possible. years, or sooner if required.
