How often check the tire pressure safety?

1, before the trip to observe the tire condition. Radial tire - that is usually said that the low-pressure tire, as long as flatness, but low on the line with the feeling of a great stretch under the pedal, not soft on the normal. High-pressure tires - is the inner tube of the bias tire, from the front to see the shoulder area is not prominent, commonly known as "not up cheek", the side and the ground contact area with the normal area is almost normal.

2, pay attention to listen to the sound of tire friction with the ground, I feel not very flat when the buffer force of the road, feeling the acceleration of the fuel situation and there is no change than usual, these are the usual accumulation of experience.
3, under normal circumstances every week to the professional tire repair shop inspection, to add pressure.

Three Golden Rules for an Accurate Measurement

• Check Only When Tires are "Cold": Always measure pressure before driving the car, or at least three hours after it has been parked. Driving even a short distance warms up the internal air, causing it to expand and produce a falsely elevated reading.
• Ignore the Tire Sidewall Number: The PSI rating molded into the rubber sidewall represents the maximum inflation limit the tire can safely hold. It is not the optimal driving pressure designed for your vehicle's handling and weight.
• Use the Vehicle Tire Placard: Always rely on the manufacturer's official recommended tire pressure. This specification is located on the silver or white sticker inside the driver’s side door jamb (B-pillar) or in the vehicle owner's manual.
