WARNING . . . . Improperly inflated tires can fail suddenly and cause an accident. The Gross Vehicle Weight rating (GVWR) is located on the F.M.V. S.S./C.M.V.S.S. certification label. The vehicle weight capacity is indicated on the Tire and Loading Information label (if so equipped). Do not load your vehicle beyond this capacity. Overloading your vehicle may result in reduced tire life, unsafe operating conditions due to premature tire failure, or unfavorable handling characteristics and could also lead to a serious accident. Loading beyond the specified capacity may also result in failure of other vehicle components. Before taking a long trip, or when ever you heavily load your vehicle, use a tire pressure gauge to ensure that the tire pressures are at the specified level. For additional information regarding tires, refer to "Important Tire Safety Information" (US) or "Tire Safety Information" (Canada) in the Warranty Information Booklet. Use only genuine GT-R tires and road wheels or an equivalent. Proper use of NISSAN recommended tires provides the greatest potential for maximum performance. - Genuine GT-R tires and road wheels or an equivalent help achieve maximum cornering performance. - Genuine GT-R tires and road wheels or an equivalent help provide road holding in the event of decreased tire pressure and punctures. - Genuine GT-R tires and road wheels or an equivalent help prevent the decrease of straight-running stability caused by uneven tire wear due to highly rigid wheels and wide tires. Do not reuse the tires that were once NOTE: . removed from the road wheels. Because the tires used with this vehicle are more rigid than ordinary tires, they may be damaged when they are removed. Even if there is no visible damage, reusing these tires is not safe and may cause an accident. In addition, the tires may be cut when they are removed from the road wheels in order to prevent scratches to the road wheels. . 8-30 Maintenance and do-it-yourself
