How much tire pressure should a car have in summer?

[PeytonMarie]

According to the season, the general tire pressure in summer is 2.3kg for the front tires and 2.5kg for the rear tires; in winter, it's 2.5kg for the front tires and 2.7kg for the rear tires. The exact values may vary slightly depending on the vehicle model and style. It is necessary to refer to the standard tire pressure chart on the car. The standard tire pressure chart can usually be found in the following places: the vehicle user manual, the label near the driver's door (near the B-pillar), the drawer next to the driver's seat, or the fuel tank cap door. Excessive tire pressure: If the tire pressure is too high and significantly exceeds the standard pressure, the tire's friction and adhesion will decrease, affecting braking performance, causing steering wheel vibration and deviation, and reducing driving comfort. At the same time, it accelerates the wear of the central tread pattern, shortens the tire's lifespan, increases body vibration, and indirectly affects the lifespan of other components. Insufficient tire pressure: If the tire pressure is too low and significantly below the standard pressure, it increases the friction coefficient between the tire and the road surface, leading to higher fuel consumption. It also makes the steering wheel heavy and prone to deviation, among other factors that are detrimental to driving safety. Insufficient tire pressure increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling.

As a seasoned driver with over a decade of experience, I recommend maintaining the manufacturer's suggested tire pressure in summer, usually around 2.2 to 2.5 bar as indicated on the door frame—don't adjust it arbitrarily. High temperatures will naturally increase tire pressure slightly, but don't deliberately underinflate because of the heat. Doing so risks blowouts at high speeds and reduces fuel efficiency. I make it a habit to check tire pressure monthly with a gauge, measuring when the tires are cold for accuracy, while also inspecting tread wear. Safety comes first—unstable pressure accelerates tire aging, leading to costly replacements. Remember this small detail for safer and more economical driving.

Tire pressure management is particularly crucial in summer, as high temperatures can cause tire pressure to rise, but it should not exceed the upper limit of 35 psi. Refer to the vehicle's manual for specific values. Excessive pressure reduces grip and increases the risk of skidding, while too low pressure increases rolling resistance and fuel consumption. I always make sure to measure regularly, especially before long trips, ensuring measurements are taken when the tires are cold. This helps prevent the risk of blowouts and extends tire life. Simple maintenance like this enhances overall driving safety—don’t underestimate this routine task.

Summer is here. I usually check the recommended tire pressure directly through my phone app. For most car models, maintaining 2.3 bar when the tires are cold is sufficient. Don’t think you need to adjust it lower or higher just because the weather is hot. Too high pressure can damage the tires or even cause a blowout, while too low pressure increases fuel consumption. I recommend buying a small tire pressure gauge for easy and practical checks. Proper tire pressure reduces wear, ensures smooth driving, and saves money while being eco-friendly.
