Will a 0.1 difference in tire pressure cause the car to pull to one side?

When the difference in tire pressure exceeds 0.1 bar, the car may start to pull to one side or sway. For vehicles driving on flat ground, a 0.1 bar difference doesn't have much impact. However, for high-speed driving, the effect becomes more pronounced. The impact force from collisions or going over speed bumps can double, with most of the force acting on the tires and suspension. Under normal conditions, when the car is cold, the front tires should have a pressure of 2.2-2.3 bar, and the rear tires 2.4-2.5 bar, which is within the normal range. However, some vehicles may have front tires at 2.4-2.5 bar and rear tires at 2.2-2.3 bar. The specific values should be based on the manufacturer's recommended tire pressure. Due to thermal expansion and contraction, in summer, the tire pressure can be adjusted 0.1-0.2 bar lower than the normal value, while in winter, it can be adjusted 0.1-0.2 bar higher. Car owners should regularly monitor their tire pressure, as both overinflation and underinflation can negatively affect driving. Continuing to drive with underinflated tires can make the steering wheel heavier, cause the car to pull to one side, accelerate tire wear, reduce tire lifespan, and increase fuel consumption.
Having driven various types of vehicles for many years, I believe whether a 0.1 bar difference in tire pressure will cause the car to pull depends on the specific situation. If there's a 0.1 bar difference between two tires on the same axle, for example, the left side being slightly higher than the right, it can easily cause uneven contact with the ground, leading to a slight pull towards the side with lower pressure. However, if the difference is between the front and rear axles, such as the front tires being slightly higher while the rear tires are normal, the impact might be minimal. Generally, modern car designs have some tolerance for minor discrepancies, and a 0.1 bar difference is not very noticeable during straight driving. But when driving on highways or taking turns, you might feel the need to adjust the steering wheel more, affecting the handling feel. Therefore, I would recommend regularly checking tire pressure, using a tire pressure gauge to measure tires on the same axle, ensuring they are within the standard range. A small difference like this might seem minor, but over time, the car pulling can lead to uneven tire wear, affecting tire lifespan in the long run. Developing a habit of checking tire pressure once a month can help avoid many potential issues.
Hi, as a driving enthusiast who often navigates through the city, I once encountered an issue with a 0.1 bar difference in tire pressure. That day, I felt the car slightly pulling to the right but didn’t pay much attention. Later, when I checked at the shop, I found the right tire pressure was 0.1 bar lower. The technician explained that uneven pressure affects grip, and even a minor imbalance can cause the car to drift. Fortunately, I caught it in time; otherwise, it could have led to loss of control in city traffic jams. Now, I always carry a tire pressure gauge and check the pressure monthly to ensure both tires on the same axle have equal pressure. A 0.1 bar difference isn’t a big deal, but combined with worn tires or slippery roads, it can amplify the risk. During every maintenance session, I also remind my friends to check this—prevention is better than cure. Safety first; small details shouldn’t be overlooked. When the drive is smooth, it just makes the day better!
