What is the tire pressure for Jetta VS5?

[Esther]

The normal tire pressure range for the Jetta VS5 is 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 tire pressure monitoring system of the Jetta VS5 can be viewed on the central control screen. The vehicle comes equipped with a tire pressure monitoring system that provides automatic alarm alerts without manual operation. This tire pressure monitoring system uses ABS wheel speed sensors to compare the rotational speed differences between tires to determine if there is abnormal tire pressure, issuing immediate alerts if any abnormalities are detected. The module is integrated into the ABS pump. Generally, tire pressure above 2.8 bar is considered too high, and 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 of the tire, 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. Hazards of underinflated tires: 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 tire bead area and causing abnormal wear; multiplies friction between the tire and the ground, sharply increasing tire temperature, softening the tire, and drastically reducing its 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, the system will alert if the 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 tire pressure monitoring light to illuminate. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor. The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, the tire pressure warning light will illuminate. For sensor damage issues, the only solution is to replace the sensor with a new one.

I've been driving the Jetta VS5 for several years, and tire pressure is something you really need to pay attention to. The standard tire pressure is generally around 2.3 to 2.5 bar, with the exact value written on the label on the driver's side door frame. For my car, both front and rear tires are at 2.4 bar, but the SUV version might go up to 2.5 bar if equipped with all-terrain tires. You can't just guess this value—too low and it can wear out the tire sidewalls and increase fuel consumption; too high and it makes the ride bumpy and unstable, affecting safety. I recommend buying a handheld tire pressure gauge to check it yourself, taking a quick look every month or when refueling. Don't inflate too much in hot summer weather, as temperature changes cause tire pressure to fluctuate. Always adjust before long trips or when carrying heavy loads—for passenger loads, the rear tires can go slightly higher to 2.6 bar for better stability. In short, referring to the owner's manual is the most reliable. Safe driving depends on these small details—it saves money and hassle, so don't overlook it.
