side temperature. It is best to check
tire pressure outdoors before driv-
ing the vehicle.
When a tire becomes warm, the air
inside it expands, causing the tire
pressure to increase. Be careful not
to mistakenly release air from a
warm tire to reduce its pressure.

WARNING
Do not let air out of warm tires
to adjust pressure. Doing so
will result in low tire pressure.
Incorrect tire pressures detract from
controllability and ride comfort, and
they cause the tires to wear abnor-

2) Under inflated tire (tread worn

Rolling resistance is high, so

3) Over inflated (tread worn in the

Ride comfort is poor. Also, the
tire magnifies the effects of
road-surface bumps and dips,
possibly resulting in vehicle
damage.
If the tire inflation pressure label
shows tire pressures for the vehicle
when fully loaded, adjust the tire
pressures to the values that match
the loading conditions.
WARNING
Driving at high speeds with
excessively low tire pressures
can cause the tires to deform
severely and to rapidly heat
up. A sharp increase in tem-
