You can get the most from your tires by keeping them inflated to the
recommended pressures when cold. Under-inflation or over-inflation
reduces tire life and safety; over-inflation also reduces comfort. How
ever, do not bleed air from tires when they are warm or hot even
though the gauge reading is higher than the recommendation, since
this could lea(j to under-inflation when they become cool.
