GM Service Manual Online
For 1990-2009 cars only

Notice: Due to the tire's speed rating there are special tire repair procedures that must be followed.

The EMT tire can be patched or plugged but, in the tread area only.

If more than one patch or plug is used, the speed rating on the tire is reduced.

Special servicing techniques are also required due to the tire's unique reinforced sidewalls. This pertains to mounting and dismounting of the tire to or from the wheel.
