It is vital to maintain proper tire inflation pressures for 1991 Lexus LS400 tires. Low tire pressure will result in tire underinflation while high tire pressure will result in tire overinflation, which can decrease fuel efficiency, lead to uneven tire tread wear and reduce tire life, compromise tire safety and cause tire blowout. Check 1991 Lexus LS400 tire pressure regularly, and monitor 1991 Lexus LS400 tire inflation pressures to avoid driving with overinflated or underinflated tires.
Tire inflation listed on tire sidewall is the maximum air pressure the tire can hold to carry its maximum load, and not the recommended tire pressure for 1991 Lexus LS400. Use 1991 Lexus LS400 recommended tire pressure settings listed on the tire pressure chart found in 1991 Lexus LS400 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 1991 Lexus LS400 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 1991 Lexus LS400 may have different recommended tire inflation pressures for front and rear tires, especially if equipped with staggered tires. Keep your 1991 Lexus LS400 tires inflated at recommended tire inflation pressures at all times for your driving comfort and safety.
If you replace 1991 Lexus LS400 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 1991 Lexus LS400 tires. 1991 Lexus LS400 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. 1991 Lexus LS400 replacement tires must have equal or greater speed rating compared to the original equipment tires if your 1991 Lexus LS400 speed capability is to be maintained. It is recommended that tire installers refer to the 1991 Lexus LS400 owner’s manual to identify any tire speed rating restriction or recommendation that could affect the operation of the vehicle. If your 1991 Lexus LS400 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 1991 Lexus LS400 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 1991 Lexus LS400 manual to find its original equipment tire sizes and load ratings. Always refer to the 1991 Lexus LS400 owner’s manual for any specific safety advice regarding the application of 1991 Lexus LS400 replacement tires.
