put more in than you need and then the release valve to work down to the target pressure plus a squidge extra
JACO ELITE PRO available from Amazon. It's dead accurate and will outlast you! There's many versions, check them out. Not expensive either.
Never trust their reading, the pressures vary considerably. Good piece of kit though, but use a trusted gauge for actual readings.
I've got this one, had it for over 20 years and still in regular use. https://www.tuning-s-line.com/catal...SSURE-ALUMINUM-CAR-TYRES-OFF-ROAD-MOTORCYCLES
If you can get one, this Oasser 20V Tyre Inflator Air Compressor Cordless Car Tyre Pump with Rechargeable Li-ion Battery, LCD Digital Pressure Gauge LED Lights USB Cable for Car Bicycle Tyres and Other Inflatables 120PSI P2S Amazon are current out, but they may be available elsewhere. Used to double check it with a hand gauge afterwards, now given up as there was never any difference.
