IT IS NORMAL FOR AIR PRESSURE TO BUILD UP IN A TIRE DUE TO
DRIVING CONDITIONS; THEREFORE. DO NOT LET AIR OUT OF
TIRES TO REDUCE THIS INCREASE IN PRESSURE.
You can get the most from your tires by keeping them inflated to
the recommended pressures when cold. Under-inflation or over-infla-
tion reduces tire life and safety; over-inflation also reduces comfort.
However, do not bleed air from tires when they are warm or hot even
though the gauge reading is higher than the recommeI}dation, since
this could lead to under-inflation.
