What is the reason for the steering becoming lighter after changing new tires?

[SanHeidi]

The reason for the steering becoming lighter after changing new tires is that the tire pressure is higher. The principle behind the steering becoming lighter after changing new tires: When the original tire pressure was at a normal level, the new tires have higher pressure after replacement, which means the rolling resistance decreases. As a result, the steering naturally feels lighter. The importance of car tire pressure: Both excessively low and high tire pressure can affect the lifespan of the tires and fuel consumption. High tire pressure concentrates the vehicle's weight on the center of the tread, leading to rapid wear in that area. Conversely, low tire pressure can cause uneven tire contact with the road, resulting in wear, increased rolling resistance, and higher fuel consumption.
