Battery - Mercedes-Benz 2002 M-Class Operator's Manual

If a tire constantly loses air, it should be inspected for
damage.
The spare tire should be checked periodically for
condition and inflation. Spare tire will age and become
worn over time even if never used, and thus should be
inspected and replaced when necessary.
Warning!
Do not overinflate tires. Overinflating tires can
result in sudden deflation (blowout) because they
are more likely to become punctured or damaged
by road debris, potholes etc.. Follow recommended
inflation pressures.
Do not overload the tires by exceeding the specified
vehicle capacity weight (as indicated by the label
on the driver's door latch post). Overloading the
tires can overheat them, possibly causing a
blowout.
