To ensure reliable measurements, MICHELIN recommends using a pressure gauge independent of the one on the compressor. The precision digital or needle pressure gauges (0 to 4 bar: 0-60 Psi) usually sold in agricultural dealerships or from your tyre dealer are very suitable. However, check their reliability over time by comparing the measurements with a more recent manometer. Humidity, weather and shocks can all cause these gauges to go out of adjustment. This can lead to the application of an actual pressure that differs from the one displayed. Under-inflation has a number of consequences for performance: damage to the tyre carcass (breakage), faster and/or irregular wear, increased fuel consumption, etc. The consequences of over-inflation are less serious, but a pressure that is too high will not optimise tyre performance: reduced traction capacity with a higher slip rate, or a reduced footprint that increases soil compaction. Thanks to AGROPRESSURE, you now know how much pressure to apply, just remember to check it from time to time.
