Is it safe to drive on the highway with a tire pressure of 2.6 in winter?

The issue of driving on the highway with a tire pressure of 2.6 in winter. The normal tire pressure range for most cars is between 2.3-2.5, and in winter, the pressure can be increased by 0.2-0.3. The following is an introduction to tire pressure: The importance of tire pressure: Tire pressure, strictly speaking, refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and damage to the engine will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the performance and power of the car. Precautions for tire pressure: While driving, pay attention to the sound of friction between the tires and the ground, feel the cushioning force when driving over uneven roads, and notice if there are any changes in acceleration when stepping on the gas compared to normal conditions. These are all experiences accumulated over time. Normally, check and replenish the tire pressure at a professional tire repair shop every week.
With my extensive winter driving experience, running at 2.6 tire pressure on highways requires extra caution. Most vehicles have the manufacturer's recommended tire pressure values labeled on the driver's side door frame – you should definitely check yours. For instance, my SUV requires 2.3 when cold, and even inflating to 2.5 for winter highway driving makes me nervous. Excessively high tire pressure is particularly hazardous on highways – it reduces the tire's contact patch, increasing risks of skidding during sharp turns and significantly extending braking distances, especially in wet conditions. Remember, tire pressure naturally rises by about 0.2 when the tires heat up after inflation. This becomes even riskier if summer's residual high pressure wasn't properly released. Just last week, I witnessed a driver experience a blowout at 3.0 pressure on the highway. My advice: always reset to standard cold pressure before departure, and don't hesitate to check tire conditions at rest stops every two hours.
After twenty years of repairing cars, I've seen too many tire pressure issues. The number 2.6 depends on the vehicle condition: it's definitely high for regular family sedans, but common for off-road vehicles with AT tires. The key is whether you measured the tires when cold - many people mistakenly think 2.5 is normal when measured on warm tires. During highway driving, tire friction causes temperature rise, turning 2.6 into 2.8 or even 3.0. Once I found someone's front left tire at 2.9 causing steering instability. Actually, tires fear localized overheating most - uneven pressure easily leads to blowouts. I recommend carrying a digital tire gauge, releasing excess air before departure, and checking tire temperature uniformity during breaks. When it comes to safety, it's better to check one more time than be lazy once.
