Is There Any Impact When the Left and Right Tire Pressure Differs by 15?
2 Answers
A difference of 15 in left and right tire pressure will have some impact. A difference of 0-10kpa between left and right tire pressure is within the normal range. When the tire pressure difference exceeds the normal range, it can cause abnormal tire wear, shortening the tire's lifespan, and the car may also experience pulling or swaying. Normal tire pressure range: According to the international GBT2978-2008 standard, the standard tire pressure for standard tires is 2.4-2.5bar. Methods to adjust tire pressure: When the vehicle is unloaded or half-loaded, it is more appropriate to adjust the tire pressure to the lower limit of the standard value. When the vehicle is fully loaded, the tire pressure should be adjusted to the upper limit of the standard value. For new tires, the standard tire pressure should be increased by about 0.2bar. For old tires, the tire pressure should be appropriately reduced according to the standard. If the wear is severe, the tire pressure should be set to the lower limit of the standard. Comfort-type soft tires should be increased by about 0.2bar above the standard pressure, while performance-type hard tires should be set to the lower limit of the standard pressure.
As someone who frequently drives long distances, I place great emphasis on driving safety, so a 15-unit difference in tire pressure between the left and right tires definitely has an impact. This can cause unstable vehicle handling, such as the car pulling to the side with lower tire pressure when turning, especially on highways or slippery roads, which can easily lead to accidents. Braking distance will also increase because uneven tire contact affects grip. Over time, tire wear will accelerate, and uneven wear on both sides can cause premature tread deterioration, increasing the risk of a blowout. I recommend stopping immediately to check the tire pressure if such a large difference is detected, using a tire pressure gauge to balance it to the standard value. Make it a habit to check your tire pressure monthly, and adjust it properly during seasonal changes to avoid safety hazards. If you're unsure how to do it, visit a professional shop to check if the suspension system is damaged—safe driving should never be taken lightly.
