RV Tire Pressure Monitoring Systems

What is an RV TPMS and why do I need one?

An RV tire pressure monitoring system (TPMS) uses sensors mounted on each valve stem to report real-time PSI and tire temperature to a dash-mounted display. Underinflation and heat buildup are the two leading causes of RV tire blowouts, and a TPMS gives you advance warning before a slow leak or overheating tire turns into a roadside failure. Most RV-specific systems handle pressures up to 230 PSI to cover both motorhome and trailer applications.

Will these tire pressure monitoring systems work on travel trailers and fifth wheels?

Yes. The systems in this collection support motorhomes, travel trailers, fifth wheels, and toy haulers, with sensor counts ranging from 4 to 22 wheels depending on the kit. For longer rigs, look for a system that includes a signal repeater to maintain a stable connection between the rear trailer sensors and the cab-mounted monitor. You can also pair a TPMS with other safety upgrades from our RV Electronics collection.

Are the sensors flow-through or cap-style, and does it matter?

Both styles are represented in this collection. Cap-style sensors thread onto the valve stem and are quick to install, but you must remove them to add air. Flow-through sensors let you inflate without removing the sensor, which is the better choice for dual rear wheels and inner duals where valve access is limited. Check the product spec for sensor weight as well, heavier sensors on long valve stems can stress the stem at highway speeds.

How are these systems powered and installed?

Most RV TPMS monitors run off a 12V outlet or USB power, with internal rechargeable batteries for backup. Sensors are battery-powered (typically CR1632 or similar coin cells) and screw on in minutes, no wiring required. After mounting the sensors, you pair each one to a specific wheel position through the monitor menu and set your high/low PSI and temperature alarm thresholds. For shore power adapters and 12V accessories, see our RV Plug Adapters collection.

Does United RV Parts offer free shipping on TPMS orders?

Yes, orders over $100 ship free within the contiguous US, which covers nearly every system in this collection. If you need help confirming sensor count, pressure range, or compatibility with your rig, text or call our team at 817-984-1852 before ordering.
