What is the normal tire pressure for Tesla?
2 Answers
Tesla's normal tire pressure range is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard requirements. To check the current tire pressure of your Tesla during daily driving, you can activate the tire pressure monitoring system, and the tire pressure values will be displayed on the central LCD screen of the instrument panel. The specific method is to press the LCD adjustment button on the left combination instrument of the steering wheel to switch to the tire pressure monitoring system interface. Generally, a tire pressure exceeding 2.8 bar is considered too high, while a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern of the tire, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increases friction coefficient 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 parts, 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 between the tire and ground, sharply raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no seal on top, four small spikes at the bottom, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Typically, an alarm is triggered when pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset promptly, the system will still record the previous data, causing the indicator light to remain on. Simply perform a tire pressure reset to resolve this. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged due to impact while driving, the tire pressure warning light will illuminate. For sensor damage, the only solution is to replace it with a new one.
After driving a Tesla for so many years, I know that the normal tire pressure is generally between 42 to 45 PSI, depending on the model, such as the Model 3 or Y. If the tire pressure is too low, the tires wear out faster, and the energy consumption increases by dozens of kilometers; if it's too high, the ride becomes harder, and the braking distance increases, which really affects the driving experience. I make it a habit to check once a week, using a portable tire pressure gauge to measure the cold tire state for the most accurate reading. Usually, I pay attention to temperature changes, as you might need to add a bit more air in winter. Don't rely solely on the onboard system; manual confirmation is best to keep things safe and easy.
