Recommended tire pressure for 2014 Lexus IS350 is determined by the manufacturer based on its characteristics and original equipment tire sizes. You can find 2014 Lexus IS350 recommended tire pressure in owner's manual or on a tire placard on the side of driver's door or door jam. 2014 Lexus IS350 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 2014 Lexus IS350. Your 2014 Lexus IS350 may also have different recommended tire pressure settings for front and rear tires, especially if equipped with staggered tires.

To check 2014 Lexus IS350 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 2014 Lexus IS350 tire inflation to the recommended tire pressure settings as needed by adding or releasing air.

If you replace 2014 Lexus IS350 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.
