Checking tire pressure (Mercedes-Benz Sprinter 903)

Always measure pressure on cold tires. During the trip, the tires heat up and the pressure in them increases, so if you measure the pressure immediately after the trip, the result will be distorted. Preventive blood pressure checks should be performed every three to four weeks. A drop in pressure of approximately 1.5% per month is normal. If this value is higher, check the tire more carefully. Wheel valves should always be covered with caps: if dirt gets into the valve, the needle may jam and it will not close hermetically. The tire pressure must not fall below the minimum permissible value. The sticker on the body of your vehicle indicates the tire pressure values for your vehicle. Increasing the tire pressure by 0.2-0.3 bar above the norm has some advantages: the steering becomes more sensitive, the tires wear out more slowly and even fuel consumption is slightly reduced. Disadvantage: the damping properties of the tires are reduced.
