Lexus RX450h Recommended Tire Pressure

Check Lexus RX450h tire pressure charts with recommended tire inflation pressures for Lexus RX450h tires to improve fuel efficiency, extend tire life and drive safely. Select your Lexus RX450h year.

It is vital to maintain proper tire inflation pressures for Lexus RX450h tires. Low tire pressure will result in tire underinflation while high tire pressure will result in tire overinflation, which can reduce fuel efficiency, lead to uneven tire tread wear and decrease tire life, compromise tire safety and cause tire blowout. Check Lexus RX450h tire pressure regularly, and monitor Lexus RX450h 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 Lexus RX450h. Use Lexus RX450h recommended tire pressure settings listed on the tire pressure chart found in Lexus RX450h 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 Lexus RX450h 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 Lexus RX450h may have different recommended tire inflation pressures for front and rear tires, especially if equipped with staggered tires. Keep your Lexus RX450h tires inflated at recommended tire inflation pressures at all times for your driving comfort and safety.

If you replace Lexus RX450h 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 Lexus RX450h tires. Lexus RX450h 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. Lexus RX450h replacement tires must have equal or greater speed rating compared to the original equipment tires if your Lexus RX450h speed capability is to be maintained. It is recommended that tire installers refer to the Lexus RX450h owner’s manual to identify any tire speed rating restriction or recommendation that could affect the operation of the vehicle. If your Lexus RX450h 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 Lexus RX450h 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 Lexus RX450h manual to find its original equipment tire sizes and load ratings. Always refer to the Lexus RX450h owner’s manual for any specific safety advice regarding the application of Lexus RX450h replacement tires.

Lexus RX450h tire pressure may fluctuate with ambient temperatures, so check Lexus RX450h tire pressure when ambient temperatures change. In winter when temperatures drop, Lexus RX450h tires may deflate by approximately 1 psi for each 10 degree Fahrenheit decrease in temperature. Maintain proper Lexus RX450h winter tire pressure by adding air to your tires as needed to the recommended tire inflation levels.

Lexus RX450h tire pressure should be checked when tires are cold, after your vehicle has not been driven for at least three hours. It is best to check your tire inflation pressure in the morning, after the vehicle has been parked overnight, using a reliable tire pressure gauge.

If your Lexus RX450h is equipped with tire pressure monitoring system (TPMS), pay attention to low tire pressure warning light being on. Ensure Lexus RX450h tire pressure sensors are working properly to stay alert and enjoy a safe ride. If your tire pressure warning light is on, check front and rear tires to make sure they are properly inflated.
