Use 2003 Lexus SC430 recommended tire pressure settings listed on the tire pressure chart found in 2003 Lexus SC430 owner's manual, on a tire placard on driver's door or door jam, inner trunk lid, in the console or on the fuel door. Recommended tire pressure for your 2003 Lexus SC430 tire sizes will be listed in one of the following pressure units: psi (pounds per square inch), bar or kPa (kiloPascals). Pay attention as your 2003 Lexus SC430 may have different recommended tire inflation pressures for front and rear tires, especially if equipped with staggered tires. Keep your 2003 Lexus SC430 tires inflated at recommended tire inflation pressures at all times for your driving comfort and safety.
If you replace 2003 Lexus SC430 original equipment tires or switch to plus size tires, make sure to follow guidelines for the application of load and inflation tables to find proper tire pressure for your new 2003 Lexus SC430 tires. 2003 Lexus SC430 tires with the same load index, regardless of tire size, may carry the same load, but may require substantially different inflation pressures. Tire load index may not be used independently to determine replacement tire acceptability for load capacity. An equal or greater load index does not always correspond to equal or greater load capacity at all inflation pressure settings. 2003 Lexus SC430 replacement tires must have equal or greater speed rating compared to the original equipment tires if your 2003 Lexus SC430 speed capability is to be maintained. It is recommended that tire installers refer to the 2003 Lexus SC430 owner’s manual to identify any tire speed rating restriction or recommendation that could affect the operation of the vehicle. If your 2003 Lexus SC430 replacement tires have a lower speed rating than the original equipment tires, your vehicle’s speed must be restricted to that of the replacement tires. Original equipment tires that come on your 2003 Lexus SC430 will have the proper tire load index, so use same or higher load index when choosing replacement tires. Tire load index tells you how much weight your tire can carry. Putting too much weight on your tires will overload them, and can cause premature tire wear, tire damage or even tire blowout. Refer to your 2003 Lexus SC430 manual to find its original equipment tire sizes and load ratings. Always refer to the 2003 Lexus SC430 owner’s manual for any specific safety advice regarding the application of 2003 Lexus SC430 replacement tires.
