Tire pressu res change by approxim ately 1 psi (7 kPa) per
F (7° C) of air tem peratu re change. Keep this in mind
when checking tire pressu re insid e a garage especially in
the winter.
speed s, maintaining correct tire inflation pressu re is very
important. Increased tire pressu re and red uced vehicle
load ing may be requ ired for high speed vehicle opera-
tion. Refer to original equ ipment or an authorized tire
dealer for recom mend ed safe operating speed s, load ing
and cold tire inflation pressu res.

Example: If garage tem peratu re = 68° F (20° C) and the
outsid e tem peratu re = 32° F (0° C) then the cold tire
inflation pressu re shou ld be increased by 3 psi (21 kPa),
which equ als 1 psi (7 kPa) for every 12° F (7° C) for this
outsid e tem peratu re cond ition.
WARN ING!

High speed drivin g with you r veh icle under load is
dangerou s. The added strain on you r tires could
cause them to fail. You could have a seriou s accid ent.
Don’t drive a veh icle load ed to maxim um capacity at
contin uous speed s above 75 mph (120 km/h).
Tire pressu re may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT red uce this norm al pressu re
build up or you r tire pressu re will be too low.
