What is the winter tire pressure in kPa?
2 Answers
The winter tire pressure is 260 kPa or 250 kPa. The tire pressure should not be too high or too low. If the pressure is too high, it will reduce the contact area between the tire and the ground, which can affect the driving safety and stability of the car. If the tire pressure is too low, the tire may experience wave deformation during high-speed driving, increasing the risk of a blowout and reducing the tire's lifespan. Regularly check the tire surface for any damage during daily use. If significant damage is found, it is recommended to repair or replace the tire immediately. When purchasing new tires, always check the production date. Tires that have been in storage for more than three years should not be purchased.
I've been driving for many years and have a lot of experience with tire pressure in winter. Generally, it's recommended to set the tire pressure between 230 to 240 kPa in winter, which is 10-20 kPa higher than in summer, because the cold temperature causes the air to contract, leading to a drop in tire pressure. If it's too low, the tire won't make proper contact with the road, increasing the risk of skidding, while too high will make the ride uncomfortably stiff. Remember to check the tire pressure when the car is cold—the specific recommended values can be found on the label inside the door frame. It's a good idea to buy a portable tire pressure gauge and measure it monthly, especially after heavy snow. Here’s an extra tip: if you frequently drive on highways, 240 kPa can improve stability. Ignoring this might lead to increased fuel consumption and tire wear. Start taking action now—developing this habit will save you both hassle and money.
