It is vital to maintain proper tire inflation pressures for Infiniti QX4 tires. Low tire pressure and underinflated tires can lead to uneven and excessive tire wear, poor handling and reduced fuel economy. High tire pressure and overinflated tires can result in reduced traction, poor braking and can even be a cause of a tire blowout. Check tire pressure regularly and maintain correct tire inflation for Infiniti QX4 to enjoy a safe and comfortable drive, save money on gas and keep auto insurance premiums low.
Recommended tire pressure for Infiniti QX4 is determined by the manufacturer based on its characteristics and original equipment tire sizes. You can find Infiniti QX4 recommended tire pressure in owner's manual or on a tire placard on the side of driver's door or door jam. Infiniti QX4 tire inflation will be listed in psi (pounds per square inch), bar or kPa (kilopascals). Keep in mind that tire inflation listed on tire sidewall is the maximum air pressure the tire can hold to carry its maximum load, and not necessarily the recommended tire pressure for Infiniti QX4. Infiniti QX4 may have different recommended tire pressure settings for front and rear tires, especially if equipped with staggered tires.
To check Infiniti QX4 tire pressure you will need to know its recommended tire inflation and a tire pressure gauge. Check tire inflation when tires are "cold" and have not been driven for at least 3 hours. Adjust Infiniti QX4 tire inflation to the recommended tire pressure levels as needed by adding air with a tire inflator.
If you replace Infiniti QX4 original equipment tires with optional or plus tire sizes, make sure to follow guidelines on how to apply tire load inflation tables when replacing Infiniti QX4 tires to find proper tire pressure for new tires. Always refer to the Infiniti QX4 owner’s manual for any specific safety advice regarding the application of replacement tires.
Infiniti QX4 tire pressure fluctuates with ambient temperatures, so when temperatures drop tires may lose approximately 1 psi of air pressure for every 10 degree Fahrenheit decrease in temperature. During winter Infiniti QX4 tires can be inflated 3 to 5 psi above the recommended tire pressure settings to compensate for lower temperatures. Never overinflate above psi indicated on tire sidewall. Make sure to check tire pressure regularly in the winter to keep tires properly inflated for a safe ride on snow and icy roads. Consult owner's manual for recommended winter tire pressure for Infiniti QX4.
If your Infiniti QX4 is made after 2007, it should be equipped with tire pressure monitoring system (TPMS) that uses tire pressure sensors to alert the driver when tire pressure is low. When Infiniti QX4 low tire pressure warning light is on, check all tires for low air pressure and inflate as needed. Refer to owner's manual on how to reset Infiniti QX4 tire pressure monitoring system.
Select model year between 1997 and 2003 to find recommended tire pressure for Infiniti QX4 tires to improve fuel efficiency, extend tire life and drive safely.
