Is There Any Impact If the Tire Pressure Differs by 0.5 Among the Four Tires?

It will increase fuel consumption and may cause the vehicle to pull to one side, affecting driving safety. Normal range of tire pressure difference: Generally, the tire pressure of a car's four tires cannot always be the same, but the difference between the front and rear tires should not be too large. A difference of around 0.1 bar is considered normal. Impact of excessive tire pressure deviation: If the tire pressure deviation is too large, it will cause different driving resistances among the tires. Especially if the tire pressure on both sides of the same axle is different, it may cause the car to pull to one side while driving, affecting driving safety. Moreover, if the tire pressure difference among the four tires is too large, it will also affect the lifespan of the tires themselves and increase fuel consumption. This is because uneven tire pressure can lead to abnormal tire wear. A tire with excessive pressure will concentrate the vehicle's weight on the center of the tread, causing rapid wear in the center. On the other hand, a tire with insufficient pressure can result in uneven contact area with the ground, increased wear, higher rolling resistance, and ultimately increased fuel consumption.
