It is vital to maintain proper tire inflation pressures for Jaguar XJ 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 Jaguar XJ to enjoy a safe and comfortable drive.
Recommended tire pressure for Jaguar XJ is determined by the manufacturer based on its characteristics and original equipment tire sizes. You can find Jaguar XJ recommended tire pressure in owner's manual or on a tire placard on the side of driver's door or door jam. Jaguar XJ 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 Jaguar XJ. Your Jaguar XJ may also have different recommended tire pressure settings for front and rear tires, especially if equipped with staggered tires.
To check Jaguar XJ tire pressure you will need to know its recommended tire inflation and a tire pressure gauge. Check tire pressure when tires are "cold" using quality tire pressure gauge. Adjust Jaguar XJ tire inflation to the recommended tire pressure settings as needed by adding or releasing air.
If you replace Jaguar XJ original equipment tires and switch to different tire size, make sure to follow guidelines for the application of load and inflation tables to find proper tire pressure for new tires. Always refer to the Jaguar XJ owner’s manual for any specific safety advice regarding the application of replacement tires.
Jaguar XJ 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 Jaguar XJ tires can be inflated 3 to 5 psi above the recommended tire pressure settings to compensate for lower temperatures. 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 your Jaguar XJ.
If your Jaguar XJ is made after 2007, it should be equipped with tire pressure monitoring system that uses tire pressure sensors to alert the driver when tire pressure is low. If Jaguar XJ low tire pressure warning light is on, check all tires for low air pressure and inflate as needed. If you need to reset TPMS, refer to owner's manual on how to reset Jaguar XJ tire pressure monitoring system.
