Generally, there is no need to adjust the tire pressure for a new car as long as it remains within the normal range. Here are the relevant details: 1. The recommended tire pressure for most models on the market is between 2.5-2.7 bar. When picking up a new car, simply follow the manufacturer's recommended value. The recommended tire pressure may vary for each vehicle. The standard tire pressure for a vehicle can be found in the owner's manual, on the lower side of the B-pillar, or inside the fuel filler cap. 2. Whether tire pressure adjustment is necessary depends on environmental factors. Since tire pressure is not constant, it can be affected by road surface temperature or tire surface temperature. In summer, when the ground temperature is very high, the air inside the tires expands, increasing the volume, which in turn raises the tire pressure. In winter, lower temperatures cause the air in the tires to contract, reducing the tire pressure accordingly. Additionally, high-speed driving causes continuous friction between the tires and the road, which can also increase tire pressure.

After buying a car, I often get asked whether new cars need tire pressure adjustments, and I think it's a great question. As someone who has driven for many years, I'd say new cars might indeed need a tire pressure check. Manufacturers often inflate tires to a higher pressure during vehicle transportation to prevent tire issues, but this isn't ideal for everyday driving conditions. For example, when I helped a friend check his new car last time, we found the tire pressure was 10 psi higher than the recommended value in the manual, resulting in a bumpy ride and reduced seating comfort. Overinflated tires wear out faster in the center, shortening their lifespan, while underinflated tires increase fuel consumption and the risk of blowouts. The new car manual usually provides detailed tire pressure recommendations, either on the door frame or in the glove compartment. I suggest checking the tire pressure with a gauge on the first day of pickup and adjusting it when the tires are cold. This simple maintenance task takes just a few minutes but ensures a smoother and more efficient ride—don't wait until problems arise to regret not doing it.

From my experience, adjusting tire pressure when buying a new car is quite important. Once, I drove a new car without adjusting the tire pressure, and it resulted in significantly increased fuel consumption during a long trip. Later, I found out the tire pressure was too high. Manufacturers often set a standard tire pressure for transportation safety before delivery, but this isn't tailored for our daily driving. The new car manual clearly states that tire pressure should be adjusted according to different loads. If you frequently carry heavy loads or drive on highways, adjusting the tire pressure can improve handling and braking stability. I recommend buying a small tire pressure gauge as soon as possible to check it, with the target tire pressure listed on the door frame. Adjusting tire pressure can prevent overheating and damage to the tires, extend their lifespan, and even save some fuel costs. After making this a habit, I've always felt safer and more at ease while driving.

I feel it's necessary to check the tire pressure right after picking up a new car. The dealer didn't remind me when I bought the car, but I checked myself and found the pressure wasn't appropriate. New cars often come with higher factory-set tire pressure designed for transportation, which may cause a bumpy and uncomfortable ride. Overinflated tires wear out the center tread faster, while underinflation increases the risk of skidding. It's best to adjust according to the manual, using a tire pressure gauge when the tires are cold. After adjustment, the driving became much smoother.
