Why Is the Tire Pressure High in New Cars?

[MaciDella]

Reasons for high tire pressure in new cars: Tire damage causing deviation in the pressure of all four tires; High or low tire pressure leading to deviation in the pressure of all four tires; High tire temperature. Hazards of excessive tire pressure: Reduced friction and adhesion of the tires, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the tread center pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. Sharp objects like nails or glass on the road can easily penetrate the tire, causing internal cracks or blowouts. Hazards of insufficient tire pressure: Increases friction with the road surface, leading to higher fuel consumption; Makes the steering wheel heavy and prone to deviation, compromising driving safety; Increases movement of tire components, causing abnormal heat due to excessive rolling; Reduces the functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; Multiplies friction with the ground, sharply raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in blowouts; Increases tire deformation, leading to sidewall cracks and excessive heat from flexing, accelerating rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear.

I noticed that the tire pressure of new cars is usually higher when they leave the factory. This is mainly because vehicles need to be parked for long periods or stacked during transportation. Higher tire pressure helps prevent deformation from prolonged pressure, avoiding flat spots or damage. After taking delivery of the car, we should immediately check the tire pressure gauge or visit a repair shop to adjust it to the manufacturer's recommended value, which is usually indicated on the door frame label or in the manual. When I drove my new car, I experienced a very stiff ride, but after reducing the pressure to the standard value, the driving comfort improved significantly, and the tire lifespan was extended. Regularly checking tire pressure is a good habit—it ensures driving safety, reduces wear, and improves fuel efficiency. Don’t forget to check the spare tire as well; it also requires maintenance. Don’t underestimate this small detail of tire pressure—it affects overall vehicle performance. After adjustment, you’ll notice reduced noise and more responsive handling.

As a safety-conscious driver, I've noticed that new cars often come with higher tire pressure set by manufacturers to prevent tire damage during transportation, but this isn't ideal for daily driving. We should adjust the tire pressure to the recommended level before driving, otherwise it may lead to reduced handling performance, such as heavier steering or longer braking distances, increasing accident risks. When driving a new car, I make it a habit to check with a tire pressure gauge - an inexpensive yet practical tool that also helps prevent accelerated center tread wear. Proper tire pressure also improves fuel efficiency, saving money in the long run. Don't forget to consider environmental factors; cold weather may cause automatic pressure drops requiring timely adjustment. Maintaining correct tire pressure is a fundamental safety measure, especially crucial during highway driving.

In terms of car maintenance, it's common for new tires to have higher pressure to prevent deformation or flat spots during storage, making them suitable for long-term parking. I recommend adjusting the pressure to the manufacturer's suggested value either by yourself or with professional help as soon as you get the car. This value is usually indicated on the B-pillar label. Proper tire pressure ensures more even wear, extending the tire's lifespan by two to three years, and also improves ride comfort. Checking the pressure with a tire gauge is simple and inexpensive, but it helps prevent bigger issues like the risk of a blowout. Regular maintenance is a wise choice, especially during seasonal changes when tire pressure fluctuates significantly. Adjusting it ensures a more secure driving experience.
