What is the normal tire pressure for Tesla?

For the Model 3, the tire pressure typically ranges between 2.3 and 2.5. In addition to following the manufacturer's recommended standard tire pressure, it is also important to consider various other factors such as season, vehicle load, tire pressure environment, and road conditions. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates uneven wear on the central tread of the tire, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more prone to punctures, leading to internal cracks, blowouts, and potential tire bursts. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, posing risks to driving safety; Increases movement in various parts of the tire, leading to excessive rolling and abnormal heat generation; Weakens the function of cords and rubber, causing delamination or cord breakage, and excessive friction with the rim, damaging the bead area and causing abnormal wear; Multiplies friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire bursts; Increases tire deformation, making the sidewalls prone to cracks and causing flexing movements, leading to excessive heat, rubber aging, cord fatigue, and breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear.
As a Tesla owner with several years of experience, I can't be careless about tire pressure. The normal value depends on the model. My Model S has a label indicating 45 PSI, while the Model 3 is usually around 42 PSI. If it's incorrect, the problems can be serious: for example, if you drive out with low tire pressure, the car feels wobbly, the tire edges wear out quickly, and it's prone to blowouts; if the pressure is too high, although it feels firmer, the braking isn't as responsive, and you might lose control in sharp turns. I check the values monthly using the car's monitoring system or a mobile app, and it's most accurate to check when the car is cold in the morning because higher temperatures can increase tire pressure slightly. In winter, you should add some air appropriately. Developing a regular habit can extend tire life by two to three years and save some electricity costs—don't wait until the warning light comes on to panic. Additionally, always confirm tire pressure before long trips—safety first.
From a professional maintenance perspective, Tesla's recommended tire pressure should be precisely referenced to the door frame label or owner's manual, with 42 PSI typically being the standard. However, models like the Model X may require adjustments between 40-45 PSI. Temperature plays a crucial role: tire pressure may increase by 2-3 PSI during hot summer months, while dropping to lower levels in cold winter conditions necessitates timely inflation. It is advisable to use a digital pressure gauge for measurement rather than relying on simple tools. Deviations in tire pressure can lead to tire deformation and, in severe cases, cause sidewall cracks or blowouts, increasing accident risks. Rotate and inspect tires every 6 months or 10,000 kilometers, combined with regular maintenance to ensure chassis health. Proper tire pressure not only enhances handling but also optimizes steering response, helping owners save on repair costs.
