Tire inflation value listed on tire sidewall is a maximum tire pressure the tire can be inflated to, and not the recommended tire pressure for Lexus RX400h. Use recommended tire pressure listed on the tire pressure chart found on a sticker on driver's door jam or in Lexus RX400h manual. Recommended tire pressure for your Lexus RX400h tires will be listed in one of the following pressure units: psi (pounds per square inch), bar or kPa (kiloPascals). Pay attention as your Lexus RX400h may have different recommended tire pressure values for front and rear tires. Keep your Lexus RX400h tires inflated at recommended tire pressure levels at all times for your driving comfort and safety.

If you replace Lexus RX400h original equipment tires with optional tire sizes or you switch to plus size tires, make sure to follow guidelines for the application of load and inflation tables to find proper tire pressure for new tires on your Lexus RX400h. Lexus RX400h tires with the same load index, regardless of tire size, may carry the same load, but not always, and they 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.

Always refer to the Lexus RX400h owner’s manual for any specific safety advice regarding the application of Lexus RX400h replacement tires.

Lexus RX400h replacement tires must have equal or greater speed rating compared to the original equipment tires if your Lexus RX400h speed capability is to be maintained. It is recommended that tire installers refer to the Lexus RX400h owner’s manual to identify any tire speed rating restriction or recommendation that could affect the operation of the vehicle. If your Lexus RX400h replacement tires have a lower speed rating than the original equipment tires, the vehicle’s speed must be restricted to that of the replacement tires.

Original equipment tires that come on your Lexus RX400h will have the proper tire load index, so stick to that number or higher when you replace them with new 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 tire damage, premature tire wear or even tire blowout. Refer to your Lexus RX400h manual to find its original equipment tire sizes and their load ratings.
