High Speed Driving; Use Of Snow Tires; Tire Replacement - Ford 1975 Mustang II Owner's Manual

ROUTINE SERVICE
NOTE-Be sure to follow instructions for vehicle maximum loading.
High Speed Driving
If you drive
continuously above 70 mph for one hour or more, increase
the cold inflation shown on the decal by 4 psi, but do not exceed the
maximum inflation pressure shown on the tires. If you can't adjust the
pressures within these limits, it is recommended that you don't drive
over 75 mph. Always observe local speed limits and weather conditions.
Continuous driving over 90 mph requires' using high-speed-capability tires.
Use of Snow Tires
Snow tires require a 4 psi cold increase in the rear tire pressure (only)
shown on the tire decal. Do not exceed the maximum inflation pressure
shown on the tires. If the increased pressure should exceed the maximum,
use the next larger optional tire size shown on the decal. See "High Speed
Driving" for pressure adjustments recommended for these conditions.
Snow tires should be of a size and type equivalent to the rest of the tires
on the vehicle.
CAUTION-Never mix radial, belted and/or conventional type tires.
Tire Care
Check tire pressures often. The "cold" pressure should be as specified on
the tire decal or for the special conditions shown above.
It
is normal for
a "warm" tire to exceed the specified "cold" pressure, Do not let air out
of "warm"tires to adjust pressure. Inspect tires often for cuts, bruises,
or sharp objects embedded in the tread.
Tire Replacement
When you see a tread wear indicator appear as a solid band across the tread,
replace the tire.
When you are replacing tires or
wheels, it is MANDATORY that
you use only the standard or op-
tional tire sizes and types recom-
mended on the tire decal attached
to your vehicle. Use only wheel rim
widths and offsets recommended
by the car manufacturer.
