So that you never run out of air
Tires are the most underestimated component. And tire pressure is the most forgotten adjustment screw for tire health. This is because the correct tire pressure prolongs the life of the tires, prevents punctures and accidents and helps you to drive more economically.
Wait until the next service appointment? Please don't: Just like checking the engine oil level, checking the tire pressure should not be put off. Because even the tightest tires lose a little air over time. The rule of thumb often recommended is "every 14 days". This is perhaps unrealistic in hectic everyday life, but you should check once a month.
This is despite tire pressure monitoring systems (TPMS), which the majority of cars have today. This is because systems that only warn of pressure loss with an indicator light only detect sudden, but not gradual, pressure loss. Systems that display the tire pressure are generally reliable - but if the tire pressure drops evenly in all tires, this is easily overlooked. There are studies that show that cars with TPMS are almost as often under-inflated as those without TPMS. The consequence of under-inflation is that the tire is subjected to greater stress and heats up, which can quickly lead to tire death, especially on hot asphalt in summer. However, fuel consumption and service life also suffer greatly as a result.
Better too much than too little - that's the most important rule. Unless otherwise stated, the target pressure (usually found on the fuel filler flap or in the door frame) refers to cold tires. However, if you have already driven, the tires are warm: the pressure increases. But that's not all: it also rises with the outside temperature. To compensate for these fluctuations, it is advisable to always fill up with the target pressure plus 0.3 bar at the filling station. In the worst case, the vehicle's suspension becomes a little stiffer. However, wear and consumption are reduced. And very important: never release the pressure after a journey in the heat of summer: The indicated pressure often appears too high, but otherwise it may be too low later when the tires are cold.
