6 Best TPMS For Class A RV in 2026: A Practical RV Guide
Six TPMS kits for Class A motorhomes, covering dual rear tires, towed cars, 80 to 125 psi pressures and long coach signal paths.
By Hardcastle's RV Editors
10 min read6 products evaluated
A Class A motorhome puts six or more heavy tires under one rig, often with a towed car behind. This guide is built around that setup: dual rears, high pressure and a long signal path.
We compared each kit on sensor count, stated psi ceiling, sensor access for inner duals and warranty terms, then ranked them from the most complete motorhome fit to the cheapest six-tire option.

How We Built This Shortlist
Each pick was assessed across 5 criteria weighted for real-world use.
- Dual-rear tire coverage
- We compared sensor counts against the typical Class A layout of two front and four rear tires, plus a toad.
- Pressure range
- We checked stated psi limits against the 80 to 125 psi cold pressures that motorhome tires commonly need.
- Sensor access
- We weighed flow-through and cap designs by how easily an owner can add air to an inner dual.
- Signal reach
- We compared quoted range and boosters against the length of a 35 to 45 foot coach.
- Support and warranty
- We noted which kits state a warranty period or a US support line.
What Matters Before You Choose a TPM For Class A RV
Key buying criteria so you get the right fit the first time.
Dual rear tire access
A Class A usually runs dual rear wheels, and the inner tire's valve stem can be awkward to reach. Flow-through sensors let you add air without removing the sensor, which saves time at every fill. Check the listing for the words flow-through or extension, and favor metal valve stems if you choose that design.
Motorhome pressure range
Class A tires can need 80 to 125 psi cold, and a sensor needs headroom above that to read correctly. A kit that stops at 87 psi will not suit most coaches. Read the stated maximum on the title or specification list and keep it comfortably above your tire's max cold pressure.
Toad and tow-vehicle support
A Class A that tows a car doubles the tire count and adds another set of sensors to pair. Some systems track a towed vehicle or several, while others hold only a single profile. Look for a statement of tow-vehicle support or a high maximum tire count on the display.
Signal length across a coach
A 40 foot coach puts the rear tires far from a dash display, and steel framing weakens radio signals. Quoted ranges run from about 36 to 120 feet with boosters. Measure from your dash to the rear dual and add margin before you accept a quoted range.
Sensor battery type
A replaceable coin cell battery costs a few dollars and takes a minute to swap, while a sealed sensor forces you to replace the entire unit. The TST 507 Cap lists CR2032 batteries as user-replaceable, and other listings do not say. Check the product page before you buy, since a motorhome has six or more sensors to maintain.
Support when a sensor fails
A failed sensor on a motorhome can leave a key tire unmonitored for a whole season. Warranty length and support availability vary widely, and some listings give no terms. Look for a stated warranty period and a US-based support option before committing.
Match a TPM For Class A RV to Your RV
By Coach Setup
| Your situation | Recommended pick | Why |
|---|---|---|
| Class A with a toad, one screen | GUTA GT20 | Ten sensors in the kit |
| Class A and buying in stages | TST 507 Cap | Starts at four and expands to tow vehicles |
| Dual rear tires, frequent fills | Tymate TM12 Flow | Flow-through sensors skip removal |
| Six-tire coach on a budget | Flydew 6-Wheel | Six sensors with a 144 PSI ceiling |

By Budget
| Budget | Recommended pick |
|---|---|
| $40 to $70 | Flydew 6-Wheel or Tymate TM2 |
| $80 to $110 | Tymate TM12 Flow or Masoll 4-Sensor |
| $260 to $370 | GUTA GT20 or TST 507 Cap |
Flow-Through vs Cap Sensors
- Flow-through sensors
- You add air through the sensor without removing it, which helps with inner dual tires. The Tymate TM12 Flow is the example here, best paired with metal valve stems.
- Cap sensors
- Cap sensors screw onto the stem and must come off to add air, but they are light and simple. The TST 507 Cap is named as cap style, and the Masoll, Tymate TM2 and Flydew kits also screw onto the valve stem.
Most Class A owners with duals should lean toward flow-through, like the Tymate TM12 Flow, unless a stem extension already makes filling easy.
By Budget Priority
| Your priority | Recommended pick |
|---|---|
| Longest support and warranty | TST 507 Cap |
| Most sensors per dollar | Flydew 6-Wheel |
| Booster included | Masoll 4-Sensor |
| Light toad only | Tymate TM2 |
For a Coach With a Towed Car Specifically
- Look for
- At least ten sensors or tow-vehicle expansion, and a display that can hold several tire positions.
- In this comparison
- The GUTA GT20 comes with ten sensors and handles up to 24 tires of data. The TST 507 Cap can monitor the coach and up to four towables.
When to Spend More
- Spend more if
- Spend more if the coach tows a car: the GUTA GT20 starts with ten sensors, and the TST 507 Cap adds a three-year warranty and tow-vehicle tracking.
- Save if
- Save if you only need the coach itself: the Flydew 6-Wheel covers six tires and reads to 144 PSI for a low cost.
Before You Bring One Home
How many sensors does a Class A motorhome need?
A typical Class A has six tires, so a six-sensor kit covers the coach. A toad adds four more, which is why the GUTA GT20's ten sensors fit that setup well.
Will a TPMS read the inner dual tire?
It can, because the sensor sits on that tire's valve stem. The practical issue is adding air, which is why the Tymate TM12 Flow suits duals better than standard screw-on types.
Is the TST 507 Cap worth the premium over the Tymate TM2?
If you want a multi-year warranty, replaceable batteries and tow-vehicle support, yes. The Tymate TM2 is cheaper but stops at 87 PSI, which is below many motorhome tire pressures.
How do I install a TPMS on a Class A?
Remove the valve caps, thread the labeled sensors onto each stem, and power the monitor. Check each reading before driving, and verify the signal from the back of the coach. Add a booster or repeater if any tire drops out.
What should I do if one sensor loses signal?
Check the battery first, then the position and any metal obstruction between the sensor and the display. A booster often fixes it on a long coach. If the sensor is sealed and still dead, replace the unit.
