What is the appropriate tire pressure in summer?

The tire pressure of Pacific Auto Network in summer is between 2.3 bar and 2.5 bar, which is the most normal figure, because in summer, with the increase of air temperature and road surface temperature, when driving at high speed or long distance, the tire pressure is easy to rise, too high tire pressure is easy to cause the brakes to get out of control, and it will explode when encountering bumps or depressions on the ground.

Generally, the values between 2.3 bar and 2.5 bar are the most normal under high temperature in summer. The decrease of temperature in winter can appropriately increase the tire pressure of the car because of the heat generated by friction.

In fact, according to the season, the standard and suggested data given by the industry are: in general, the front wheel is 2.3kg and the rear wheel is 2.5kg in summer; In winter, the front wheel is 2.5kg and the rear wheel is 2.7kg. According to different models and styles, the tire pressure data is slightly different, but it will not be very different. In this regard, I suggest you refer to the standard barometer in the car. Automobile standard barometer can usually be found in the following places, such as vehicle user's manual, label next to cab door (near B-pillar), drawer next to vehicle driver's seat, fuel tank cover door, etc.

What are the disadvantages of high tire pressure and insufficient tire pressure?

1. Insufficient tire pressure: Generally, cars travel very fast, especially on urban expressways and even expressways, and tire shapes are in a state of high frequency alternation. If the air pressure is insufficient, the tire deformation will increase, the tread lines on both sides of the tread will be excessively worn, and the carcass will be distorted because it can't resist the ground pressure, which will lead to an increase in temperature and accelerated tire wear, which will eventually lead to a puncture. Therefore, insufficient tire pressure is also the cause of puncture, so we must pay attention to it.

2. Too high tire pressure: It is common sense that too high tire pressure will make the tire hard, lose its elasticity and shock absorption ability, and lead to poor grip. Excessive wear of the central tread will produce uneven tread depth, and the tire may burst due to unbearable excessive pressure when driving at high speed.

Needless to mention the danger of puncture, especially when driving at high speed, it will even endanger the lives of drivers and passengers, so there is a danger of puncture if the tire pressure is too high or too low, which should not be underestimated.
