Accurately measuring tire pressure can be tricky, as you've experienced with getting different readings from multiple gauges. Here are some tips to get the most precise measurement:
Use a high-quality, calibrated digital tire pressure gauge. Digital gauges tend to be the most accurate compared to analog dial or pencil-type gauges

. Look for one that is rated for the pressure range of your tires (e.g. 160 psi for many RV or truck tires)
1
.
Check the pressure when the tires are cold, before driving, as heat from driving can cause pressure to increase and give a false reading
1
. Let the tires cool down for at least 30 minutes after driving.
Compare the reading from your gauge to the tire pressure monitoring system (TPMS) in your vehicle, if equipped. TPMS is generally accurate to within +/- 1 psi according to AAA testing

, but may not alert until a tire is 20-30% below the recommended pressure.
If you get significantly different readings between multiple gauges (4+ psi difference), one or more gauges may be inaccurate
1
. Take your gauge to a tire shop that has a calibrated master gauge to compare against for the most precise check
1
.
Don't rely on gas station air pump gauges, which are often abused and inaccurate
1
. Invest in your own quality gauge.
Even if readings vary slightly between gauges, the most important thing is to consistently use the same gauge, check pressure regularly, and keep tires inflated to the manufacturer's recommendations for your vehicle. This will maximize tire life, handling, and fuel efficiency.
