Tire pressure monitoring systems (TPMS) alert you to low pressure or high temperature before a blowout leaves you stranded—or worse. RV tires run at higher pressures than passenger vehicles, and the consequences of failure are more severe with heavier rigs at highway speeds. Modern TPMS units use wireless sensors that mount on or inside your valve stems, transmitting real-time pressure and temperature data to a cab-mounted display or smartphone app.

What to Know Before You Buy

• Count all the tires you want monitored: Your tow vehicle, motorhome, trailer, and towed vehicle may all need sensors.
• Cap-mounted sensors are easier to install and move between vehicles; flow-through sensors allow adding air without removal.
• Signal range matters for long rigs—verify the system works reliably from your rear trailer axles to your cab.
• Set alert thresholds based on your tire manufacturer's recommendations, not generic defaults.
