At what tire pressure should you not drive?

[DiEli]

Since there is no fixed optimal tire pressure for each tire, there is also no fixed value below which you should not drive. However, as long as the pressure is not lower than the manufacturer's recommended value, it is generally safe, typically ranging from 2.2 to 2.5. In winter, it is best to aim for the higher end of the recommended range. Driving with excessively low tire pressure can lead to the following issues: 1. Increased fuel consumption: Low tire pressure increases the contact area between the tire and the road, thereby increasing friction and rolling resistance, which naturally raises fuel consumption. 2. Reduced tire lifespan: Similarly, the larger contact area accelerates tire wear, shortening the tire's service life. 3. Higher risk of blowouts: The increased friction raises tire temperature, making the tire softer and weaker. When the tire can no longer support the vehicle's load, especially at high speeds, blowouts become more likely.
