3.7 Run-Flat Tire Service
Basic Run-Flat / EMT Information
A Run-Flat / EMT tire is capable of supporting the vehicle’s weight, even when the air
pressure is zero psi.
The sidewall of the tire is approximately six times thicker than a standard tire. A
standard tire’s sidewall goes flat at low pressure, causing the customer to change the
wheel before driving the vehicle. A Run-Flat / EMT tire can support the vehicle’s
weight, even at zero pressure. The customer can drive on the tire to the dealer for
service, as far as fifty miles. The customer no longer has to jack up the vehicle and
install a spare tire and wheel.
Run-Flat “Zero Pressure” Tires and Rims
WARNING: Most run-flat designs require an approved inflation cage
due to possible extremely high bead seating pressure
required.
NOTE: Sidewalls are extremely tough, require liberal lubrication,
and complete positioning into the drop center before proper
removal.
Care must be taken when mounting tires on vehicles equipped with the Low Tire
Pressure Warning System (LTPWS). Each wheel has a sensor secured inside the rim.
Damage to the air pressure sensor is a costly mistake. Consult the manufacturer’s
specifications and procedures to properly demount and service this wheel
combination.
