I dropped GS ERS a few years back when I called to get a flat on the truck swapped for the spare. The operator said if my spare needed air, the driver would require an extra payment. Air was not included with a tire change. When the wrecker driver showed, he cranked up his air compressor to use on the jack and impact wrench. I asked that since he had the air there, if he would top off the spare ... it was about 5 psi low. He did and no charge.
As soon as we got to our destination, I called and cancelled GS ERS.
