What is the tire pressure for Tesla?
2 Answers
Tesla's tire pressure range depends on the type of tires installed. The recommended tire pressures for different tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. 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 pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Excessive stretching of tire cords reduces elasticity, increasing the load on the vehicle during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate the tire, leading to internal cracks or blowouts. Hazards of underinflated tires: Increases friction with the road surface, raising fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement of tire components, leading to abnormal heat due to excessive rolling; Reduces the functionality 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 with the ground, rapidly increasing 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 flexing, causing overheating, rubber aging, cord fatigue, and breakage, while also enlarging the contact area and accelerating shoulder wear.
When picking up my Model 3, I remember glancing at the tire pressure sticker attached to the driver's door frame. My Standard Range version requires a cold tire pressure of 2.9 bar (42 psi), which feels the most stable when driving. Once when it dropped to 2.6 bar on a cold day, the central display immediately popped up a yellow warning sign, and the energy consumption jumped from 13 to 16 kWh per 100 km. The service center guy explained that low tire pressure causes significant sidewall deformation, increasing rolling resistance and damaging the rims. They used an electronic tire pressure gauge with temperature compensation to inflate mine to 3.0 bar and recommended checking it every two weeks when the tires are cold. By the way, it's best to readjust when seasonal temperature differences exceed 10°C, as thermal expansion and contraction can cause a 0.3 bar variation.
