What is the normal tire pressure for the Tiguan L?
2 Answers
The normal tire pressure for the Tiguan L is generally between 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and decreased by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard. The Tiguan L displays tire pressure on the central information screen of the dashboard. The direct tire pressure monitoring system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the data for each tire. The system automatically alerts the driver when the tire pressure is too low or if there is a leak. Generally, a tire pressure above 2.8 bar is considered too high, and a pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread of the tire, shortening its lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overextends the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; weakens the 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, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: The system typically alerts when pressure is below 1.8 bar or above 3.0 bar. In this case, the tires need to be checked and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure monitoring system is not reset, it will continue to display the previous data, causing the indicator light to stay on. Simply reset the tire pressure monitoring system. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the inflation valve. If the sensor is damaged during driving, the tire pressure warning light will illuminate. In this case, the only solution is to replace the sensor with a new one.
When I drove the Tiguan L for a while, tire pressure issues were quite common. The normal tire pressure range is between 2.3 to 2.5 bar, approximately 33 to 36 psi, depending on your vehicle's load. When unloaded, 2.3 bar is sufficient, but when fully loaded or driving at high speeds, it's safer to adjust to 2.5 bar. I make it a habit to check regularly, using an inexpensive tire pressure gauge to measure the cold tire pressure every month. Especially in summer when hot weather can increase tire pressure, I inflate slightly less; in winter when temperatures drop, I add about 0.1 bar to compensate. Remember to refer to the recommended values on the door frame label, as they may vary for different wheels. Too high tire pressure causes faster wear in the center of the tire and reduces grip; too low increases fuel consumption and makes the car prone to skidding. Once, during a long trip, low tire pressure nearly caused an accident, and since then, I've made it a routine—simple steps to ensure smooth and safe driving.
