Recommended tire pressure for Infiniti Q40

It is vital to maintain proper tire inflation pressures for Infiniti Q40 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 Infiniti Q40 tire pressure regularly, and monitor Infiniti Q40 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 Infiniti Q40. Use Infiniti Q40 recommended tire pressure settings listed on the tire pressure chart found in Infiniti Q40 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 Infiniti Q40 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 Infiniti Q40 may have different recommended tire inflation pressures for front and rear tires, especially if equipped with staggered tires. Keep your Infiniti Q40 tires inflated at recommended tire inflation pressures at all times for your driving comfort and safety.

If you replace Infiniti Q40 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 Infiniti Q40 tires. Infiniti Q40 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. Infiniti Q40 replacement tires must have equal or greater speed rating compared to the original equipment tires if your Infiniti Q40 speed capability is to be maintained. It is recommended that tire installers refer to the Infiniti Q40 owner’s manual to identify any tire speed rating restriction or recommendation that could affect the operation of the vehicle. If your Infiniti Q40 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 Infiniti Q40 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 Infiniti Q40 manual to find its original equipment tire sizes and load ratings. Always refer to the Infiniti Q40 owner’s manual for any specific safety advice regarding the application of Infiniti Q40 replacement tires.

Infiniti Q40 tire pressure may fluctuate with ambient temperatures, so check Infiniti Q40 tire pressure when ambient temperatures change. In winter when temperatures drop, Infiniti Q40 tires may deflate by approximately 1 psi for each 10 degree Fahrenheit decrease in temperature. Maintain proper Infiniti Q40 winter tire pressure by adding air to your tires as needed to the recommended tire inflation levels.

Infiniti Q40 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 Infiniti Q40 is equipped with tire pressure monitoring system (TPMS), pay attention to low tire pressure warning light being on. Ensure Infiniti Q40 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.
