Too low or too high a tire pressure can affect the life and fuel consumption of the tire itself.
Not long ago, I had a friend who made a car tyre change, but the steering wheel became heavy. This is very strange because he always hears
that the steering wheel becomes lighter after the car tyre are changed.
Today, roadbuck shared with you why the steering wheel will become lighter and heavier after the car tyre are changed.
It may be too much.
First, it needs to be confirmed that if the direction of the car tire changes, it may mean that the tire pressure of the new tire is too
high. The principle is simple. For example, the tire pressure of the original tire is normal. After the car tire are changed, high pressure
means that the rolling resistance is small, so the direction naturally becomes lighter.
Let’s take a look at the right car tire pressure.
[Appropriate car tire pressure]
1. According to the provisions and requirements of GBT2978-2008 international standards:
Standard tire: 2.4-2.5bar
Reinforced tire: 2.8-2.9bar
Maximum air pressure: no more than 3.5bar
2. Other factors to be quoted:
(1) Seasonal factors:
One. Winter: The height is appropriately increased by about 0.2 bar depending on the standard pressure of the car tire.
Summer: The standard lower air pressure limit for car tires.
In summer, the car is parked in the open air, and the air pressure is usually about 0.1 bar lower than the standard to avoid high temperature
