TYPES OF TIRES Summer tires The GT-R summer tires are made from a specially formulated rubber to maximize the vehicle's performance capabilities. Performance of summer tires is substantially reduced when temperatures are less than 328F (08C) so you must drive carefully. NISSAN recommends the use of winter or all-season tires on all four wheels if you plan to operate your vehicle in snowy or icy conditions when temperatures are less than 328F (08C). WARNING . When changing or replacing tires, be sure all four tires are of the same type (Examples: Summer or All Season) and construction. A GT-R certified NISSAN dealer may be able to help you with information about tire type, size, speed rating and availability. Replacing tires with those not originally specified by NISSAN could affect the proper operation of the TPMS. For additional information regarding tires, refer to "Important Tire Safety Information" (US) or "Tire Safety Information" (Canada) in the Warranty Information Booklet. Frequently check the tire pressure information display on the monitor screen and adjust pressure of each tire properly. See the separate Multi Function Display Owner's Manual. It can be difficult to tell if a run-flat tire is underinflated or flat. Check the tire pressures as described earlier in this section. If the tire becomes under-inflated while driving, the low tire pressure warning light will come on. If the tire becomes flat while driving, the low tire pressure warning light and the run-flat tire warning display will come on. . WARNING Never use summer tires when the temperature is below −48F (−208C) to prevent permanent tread deformation which may cause tire damage or tire failure. This may cause a loss of vehicle control which can result in serious personal injury or death. Low tire pressure: If the vehicle is being driven with low tire pressure, the low tire pressure warning light will illuminate. . Flat tire: If the vehicle is being driven with one or more flat tires, the run-flat tire warning display will appear continuously on the vehicle information display and a chime will sound for 10 seconds. The chime will only sound at the first indication of a flat tire and the run-flat tire warning display will illuminate continuously. When the flat tire warning is activated, have the system reset and the tire checked and replaced if necessary by a GT-R certified NISSAN dealer. Even if the tire is inflated to the specified COLD tire pressure, the warning light will continue to illuminate until the system is reset by a GT-R certified NISSAN Run-flat tires Your vehicle is equipped with run-flat tires. You can continue driving to a safe location even if they are punctured. Always use run-flat tires of the specified size on all four wheels. Mixing tire sizes or construction may reduce vehicle handling stability. If necessary, contact a GT-R certified NISSAN dealer for assistance. All-season tires NISSAN specifies all-season tires on some models to provide good performance for use all year around, including snowy and icy road conditions. All-season tires are identified by ALL SEASON on the tire sidewall. 8-34 Maintenance and do-it-yourself
