Best tire pressure gauges for an RV or trailer
An RV combines the two hard parts of pressure checking: high target pressures, and a valve that may be behind another wheel. Both are readable from a specification sheet before you buy.

Only 2 of the 14 gauges in our set publish any accuracy figure — a dash in that column is the manufacturer not saying, not us not looking.
What matters here
The two specifications that decide it
Range gets you to the pressure; reach gets you onto the valve. On a motorhome with dual rear wheels the inner valve is often set deep behind the outer tire, and a compact gauge with a straight chuck simply cannot be seated on it. A dual-head chuck plus an extended hose solves it, and both are published features rather than marketing adjectives.
Check them cold, and check them often
RV and trailer tires carry heavy loads at high pressure, so a small under-inflation is a larger proportion of the load rating than it would be on a car. The same gauge-and-routine discipline applies: measure cold, use the placard figure rather than a sidewall maximum, and compare all tires against each other so a slow leak shows up as a trend.
What about TPMS on a trailer?
Aftermarket trailer TPMS is a reasonable addition and a separate purchase from a gauge — a monitoring system warns you, a gauge sets the pressure. Our TPMS coverage is planned rather than published, so this page recommends nothing there yet.
Frequently asked
What pressure do trailer tires run at?
Often 65–80 PSI, which is why a gauge reaching 160 PSI is a better fit than a 0–60 car gauge — the target sits mid-scale instead of at the top of the dial.
Can I use a car tire gauge on an RV?
Only if its range covers the target and its chuck reaches the valve. Many car gauges stop at 60 PSI, and few have the reach for a dual rear wheel.
