I use these, by Lisle: https://www.lislecorp.com/specialty-tools/tire-deflator-set
Without driving a few hours, or seeking out a dedicated off-road park, we don't have any forest service roads/trails that require airing down for traction, so I air down very rarely. These were cheap, compact, and reliable. I keep them in my console tray, along with a tire pressure gauge.
That is neat, Lisle is half an hour from me and I had never heard of those before.
