How to Set Tire Pressure?
2 Answers
The method to set tire pressure is: 1. In the tire pressure state, long press the SET button to enter parameter settings; 2. Press the SET button five times consecutively to enter tire matching for setup. The method to check car tire pressure is: 1. Unscrew the tire's valve core nut; 2. Insert the measuring head of the tire pressure gauge into the valve core; 3. Read the measured data on the tire pressure gauge. The impacts of abnormal tire pressure include: 1. Reduced friction and adhesion of the tire, affecting braking performance; 2. Causing steering wheel vibration and deviation, reducing driving comfort; 3. Accelerating wear on the central part of the tire tread, shortening tire lifespan; 4. Degrading the function of cords and rubber, leading to delamination or cord breakage, and causing excessive friction with the rim, resulting in damage to the bead area and abnormal wear.
I always check the tire pressure whenever I refuel. Going on a trip with a full carload? Inflate the tires 0.2-0.3 bar more than usual. If there are only two people in the back seats, just follow the standard pressure listed on the door label. A few months ago, during cold weather, I didn’t pay attention, and the left front tire dropped to 1.8 bar—the steering wheel even felt floaty. Now I’ve developed a habit: at the beginning of each month, I use a mechanical gauge to check the cold tire pressure. The free air pumps at gas stations are especially handy. Heard that you should reduce tire pressure when driving on the highway in summer? Don’t believe it—instead, inflate to the upper limit, as high temperatures will naturally increase tire pressure by about 0.3 bar. A digital tire pressure gauge is more accurate; those 10-yuan mechanical ones have quite a margin of error. The spare tire’s pressure is often overlooked—remember, it needs to be 0.5 bar higher than normal, so it won’t go flat after two or three years.
