The tire can operate effectively with no air pressure for up
to 200 miles (320 km) at speeds up to 55 mph (90 km/h),
but the tire would then have to be replaced. When a tire is
filled with air, it provides a cushion between the road and
the wheel. Because you won't have this cushion when
driving on a deflated tire, try to avoid potholes that could
damage your wheel and require replacement of it.
Some road hazards can damage a tire beyond repair.
This damage could occur even before you've driven
on the tire in a deflated condition. When a tire has been
damaged, or if you've driven any distance on a
deflated EMT, check with an authorized Goodyear EMT
Service Center to determine whether the tire can be
repaired or should be replaced. To maintain your
vehicle's extended mobility feature, all replacement tires
must be Extended Mobility Tires. As soon as possible,
contact the nearest authorized GM or Goodyear
EMT servicing facility for inspection and repair or
replacement. To locate the nearest GM or Goodyear
EMT servicing facility, call Roadside Assistance.
see Roadside Assistance Program on page 7-5.

Exl , . .ded mobili,., tires are cons,. Jcted
differently than other tires and could explode
during improper service. You or others could
be injured or killed if you attempt to repair,
replace, dismount, or mount an extended
mobility tire. Let only an authorized Goodyear
EMT Service Center repair, replace, dismount
and mount extended mobility tires.
The valve stems
on
your extended mobility tires have
sensors that are part of the Tire Pressure Monitor
(TPM). See Tire Pressure Monitor System (Except Z06)
on page 5-57. These sensors contain batteries which
are designed to last for 10 years under normal
driving conditions. See your dealer if you ever need to
have a wheel replaced, or if the sensors ever need
replacement.
Notice: Using liquid sealants can damage the tire
valves and tire pressure monitor sensors in your
extended mobility tires. This damage would not be
covered by warranty. Don't use liquid sealants
in your extended mobility tires.
