indicators are visible.
4. Keep tires properly inflated.
If your vehicle is equipped with
radial tires, your tires were de
signed to provide better snow trac
tion performance than bias
or bias
belted tires without snow treads.
However,
if you equip your vehicle
with snow tires, you should
use
snow tires of the same size, load
range, and construction type
as
your other tires. Vehicle speeds
should be limited to 75 mph if
snow tires are installed because
vehicle handling may
be adversely
affected.
Use of Tire Chains
Tire chains may be used on your
Vega if it
is equipped with the
standard wheel
(13" x 5"). If your
Vega
is equipped with 13" x 6"
wheels, it cannot be modified to
accept tire chains.

Wheel Replacement
Considerations
Wheels must be replaced if bent,
heavily rusted, leak air,
or if lug
nuts continually loosen.

straighten
bent wheels or use inner
tubes in leaking wheels.

reason, the replacement wheels
should
be equivalent in load capa-

city, diameter, width, offset, and
mOllnting configurations to those
originally installed
on your vehicle.
Replacement wheels
can be ob
tained from your Chevrolet dealers.
A wheel
of improper size or type
may adversely affect wheel and
bearing life, brake cooling, speed
ometer/odometer calibration,
ve
hicle ground clearance, and tire
clearance to the body
and chassis.
Replacement with
"used" wheels
which may have been subjected to
harsh operating conditions
or very
high mileage is
not recommended.
These wheels
may fail prematurely
without any prior visual indication.
