Porsche Cars N.A. recommends the use of a tire pressure gauge with an accuracy of +/- 1% to check and set the tire pressure on the 1990/91 928 models
with the "Tire Pressure Monitoring System," and all other Porsche models. The pressure gauge must be able to measure the tire pressure in increments of
0.5 psi. A digital tire pressure gauge, such as Schrader model number 100-0001 or equivalent may be used.
To properly adjust the 928 Tire Pressure Monitoring System, refer to the 1990 928 Service Information Booklet WKD 496 521, 928 Workshop Manual
Volume IV and Technical Bulletin Group 4, Number 9008.
