Tire pressure differences occur in almost every car. There are many reasons. From temperature fluctuations, when the tires are a bit lower, to simple carelessness on the part of the driver, when someone does not get a pressure gauge for months. The AvtoVzglyad portal tells about the consequences of different pressure measurements in the wheels.
Even if the wheels are new, air can escape from the tires. This usually happens when the weather and atmospheric pressure change, when the air in the tires is compressed or expanded. The wheels may also be slightly “etched” if the driver was actively driving on rough roads, often falling into deep potholes.
It is sometimes hard to understand that there is something wrong with the pressure. This is especially true for the rear wheels, because they are less loaded than the front wheels. The fact is that in the design of many tires so-called reinforced sidewalls are used, so that they withstand lateral cuts. They perfectly keep their shape, therefore it is almost impossible to determine that there is only one atmosphere in the wheel instead of the prescribed two atmospheres. The same goes for low profile tires.
What happens if a driver drives a car with differently inflated wheels. The biggest problem is that tires change the contact patch with the road. That is, the wheels get a different rolling resistance. With a semi-flat tire, the main load goes to the sidewalls, which are much stronger than the central part, and the latter bulges inwards. As a result, we see increased wheel wear.
If such a wheel is at the back and the driver is driving at city speeds (60 km/h), then it is very difficult to understand that the tire is half empty. The car behaves normally. Front wheels are fine! Meanwhile, in a critical situation, when it is necessary to maneuver sharply, such a wheel can be disassembled and the vehicle will behave differently. Reactions come a bit late, which can lead to an accident.
And if there is a discrepancy in the front wheels, the “iron horse” will begin to “sausage”, leading to the left or right on a straight line, and when braking, the steering wheel must be squeezed tightly in your hands to be in your lane. to stay. This again contributes to the creation of an extreme situation on the road. Against this background, increased fuel consumption and uneven wheel wear seem nothing.
