What Is the Recommended Tire Pressure for Mercedes-Benz Vehicles?

There are two types of TPMS: direct and indirect. Direct TPMS uses sensors inside each tire to measure PSI in real time. Indirect systems calculate pressure from wheel speed data. Either way, the goal is simple- help drivers maintain proper inflation.  

So, what is the recommended tire pressure for Mercedes-Benz Vehicles? In most models, the recommended PSI ranges between 32 and 40 PSI, depending on the vehicle and load conditions. You’ll find the exact specification on the driver-side door jamb sticker or in the owner’s manual. Sedans like the C-Class may differ slightly from SUVs such as the GLE or GLS. Therefore, checking your specific model’s requirements is always wise.  

Maintaining correct tire pressure promotes even tread wear and steady braking. On the other hand, overinflated tires can reduce grip, while underinflated tires may lead to overheating and premature wear. Keeping PSI within factory guidelines protects both performance and comfort.  

Planning a road trip? First, check your tire pressure when the tires are cold. Temperature changes can alter PSI readings, so early morning checks provide the most accurate results. Additionally, consider cargo weight. Extra luggage or passengers may require slight adjustments, as listed in your owner’s manual.  

Next, inspect tires for visible damage or uneven wear. Even with TPMS alerts, a quick visual check adds peace of mind. It’s also smart to carry a portable tire inflator and gauge. During long drives, recheck the pressure after significant temperature changes, especially when crossing state lines.  

Ultimately, keeping tires properly inflated supports stability at highway speeds and promotes better fuel economy.
