Ryobi 18V One+ Dual Function Inflator/Deflator

The Gauge

The only readout on the Inflator is an un-calibrated digital pressure gauge that allows you to both read the tire pressure and set the shut-off pressure for the automatic filling function. When done, check your tire with an accurate tire gauge. I prefer to check them cold, and not in any direct sunlight to maintain relative accuracy. If you want to take it a step further, grab yourself an infrared temperature gun and check to make certain they are all the same temperature, that way 32 lbs is 32 lbs for every tire. After all, unlike water, air expands with rising temperatures, and contracts with cooler, thus altering tire pressure. Photo: Ryan King, 2019.
