Four sensors cover exactly four tires: a tandem-axle trailer, a pickup, or a small motorhome without duallies. That keeps the kit simple and cheaper, but it also means a truck and trailer together need a second kit or a bigger set.

Only four sets made this list, so each gets a full look at pressure range, display style and sensor battery. Where a listing leaves out a spec, the entry says to confirm it.

RV Gear Lab field notes

The Rig Fit Check

Start with the job
RVenture RV Tire Pressure Monitoring System leads this shortlist for Tandem trailers needing a repeater. Use that fit as a reference point, then compare the alternatives against your own space and workload.
Specs that separate the picks
The first details to compare are 4 cap-style sensors, 4 external sensors, 0-144 psi, 4 external sensors, 0-87 psi. Confirm the exact model and included components before ordering.

Before you buy

What Matters Before You Choose a 4 Sensor RV TPM

Key buying criteria so you get the right fit the first time.

  1. 01

    What four sensors cover

    Four sensors cover a tandem-axle trailer, a pickup or a small motorhome with single rear wheels. A truck and trailer together need eight, and duallies need more. Count every tire before choosing a four-sensor set.

  2. 02

    Pressure range

    A four-sensor set is only useful if it can read your tires. The Tymate TM2 4-Set stops at 87 psi, while the Tymate TM3 4-Set and Tymate TM7 4-Set read to 144 psi. Check the listing's psi against your tire's maximum.

  3. 03

    Sensor battery type

    Cap sensors with replaceable CR1632 batteries, as on the RVenture 4-Sensor, can be refreshed for a few dollars. Sealed sensors must be replaced when the battery dies. Check whether the listing names the battery.

  4. 04

    Repeater and range

    The signal must reach the cab from the trailer. The RVenture 4-Sensor includes a repeater, and the Tymate sets list extended transmission. Check the stated range against your trailer length.

  5. 05

    Display and power

    A widescreen display is easier to read, and solar or USB power avoids wiring. The RVenture 4-Sensor uses a 5 inch screen with a magnetic mount. Look for backlight and charging details.

  6. 06

    Expandability

    Some displays can add sensors later, while a four-tire kit may be a dead end. If you may add a truck or spare, ask about expansion. Check the tire count the display handles.

Best Overall Four-Sensor · 1 of 4

RVenture RV Tire Pressure Monitoring System

RVenture RV Tire Pressure Monitoring System
  • 4 cap-style sensors
  • Replaceable CR1632 batteries
  • 5 inch widescreen display
Check price on Amazon for RVenture RV Tire Pressure Monitoring System (opens in a new tab)
Best for: Tandem trailers needing a repeater

Our take

Best for a tandem trailer or motorhome where replaceable batteries and an included repeater matter.

Why it made the shortlist

The RVenture kit includes 4 cap-style sensors with user-replaceable CR1632 batteries, a 5 inch widescreen color display and a repeater. The listing says the sensors have an anti-theft design, and the kit adds 2 installation wrenches and a magnetic suction cup mount for the dash or windshield.

It ranks first because it names the sensor type and battery and includes a repeater, which the Tymate sets do not.

What works

  • Replaceable CR1632 sensor batteries
  • Repeater included in the kit
  • Anti-theft sensor design
  • Wrenches and magnetic mount included

Watch out for

  • Pressure range is not stated here
The catch
It costs more than double any Tymate set here, and its listing does not state a pressure range in the section shown.

Best Wide-Range Tymate · 2 of 4

Tymate TM3 RV Tire Pressure Monitoring System

Tymate TM3 RV Tire Pressure Monitoring System
  • 4 external sensors, 0-144 psi
  • Six alarm modes
  • Solar and other charging
Check price on Amazon for Tymate TM3 RV Tire Pressure Monitoring System (opens in a new tab)
Best for: Tandem trailers, higher pressure

Our take

Best for a tandem trailer with tires up to about 120 psi.

Why it made the shortlist

The Tymate TM3 4-Set includes 4 external sensors that read 0 to 144 psi, with six alarm modes and a color LCD with automatic backlight. The listing says the sensors are low power, and the display charges by solar or other options.

Compared with the Tymate TM2 4-Set below, it reads up to 144 psi instead of 87 for a similar price.

What works

  • Reads up to 144 psi
  • Six alarm modes listed
  • Auto backlight on a color LCD
  • Solar charging keeps the display powered

Watch out for

  • No repeater in the box
  • Sensor battery type is not stated
The catch
Against the RVenture 4-Sensor it lacks an included repeater but costs far less.

Best Low-Pressure Tymate · 3 of 4

Tymate TM2 RV Tire Pressure Monitoring System

Tymate TM2 RV Tire Pressure Monitoring System
  • 4 external sensors, 0-87 psi
  • Six alarm modes
  • Solar and USB charging
Check price on Amazon for Tymate TM2 RV Tire Pressure Monitoring System (opens in a new tab)
Best for: Low-pressure four-tire rigs

Our take

Best for a four-tire rig with tires under 87 psi.

Why it made the shortlist

The Tymate TM2 4-Set includes 4 external sensors that read 0 to 87 psi, with six alarm modes and solar and USB charging. The listing says the sensors run for up to six months on low power, and the display has an adaptive backlight.

It is better suited to a small trailer or a toad.

What works

  • Six alarm modes listed
  • Solar and USB charging
  • Sensors use low power
  • Adaptive backlight on the display

Watch out for

  • Only 87 psi maximum
The catch
For heavier RV tires, choose the Tymate TM3 4-Set instead.

  • 1.5 psi accuracy
  • Cigarette lighter and USB power
Check price on Amazon for Tymate TM7 RV Tire Pressure Monitoring System (opens in a new tab)
Best for: Budget tandem trailers

Our take

Best for a tandem trailer on a tight budget where plug-in power is fine.

Why it made the shortlist

The Tymate TM7 4-Set includes 4 sensors that read 0 to 144 psi, with plus or minus 1.5 psi accuracy, a cigarette lighter power plug and dual USB charging. The listing says it sets up in about 5 minutes with a manual and video guides.

It is the cheapest set here and matches the Tymate TM3 4-Set on range.

What works

  • Reads up to 144 psi
  • Plug-in power, quick setup
  • Manual and video guides

Watch out for

  • No solar charging listed
  • Fewer alarm details listed

For a Tandem Travel Trailer Specifically

Look for

A set with four sensors, a range that exceeds your tire pressure and a way to reach the trailer, such as the RVenture 4-Sensor with its repeater.

In this comparison

The RVenture 4-Sensor includes a repeater and names its battery, while the Tymate TM3 4-Set reads to 144 psi.

When to Spend More

Spend more if

Spend more on the RVenture 4-Sensor for the repeater and replaceable batteries, or the Tymate TM3 4-Set for solar charging and 144 psi.

Save if

Save with the Tymate TM7 4-Set, which is the cheapest set here and reads to 144 psi.

FAQ

Before You Bring One Home

Do four sensors cover a travel trailer?

A tandem-axle trailer has four tires, so the RVenture 4-Sensor or a Tymate 4-Set covers it. A triple-axle needs six.

What mistake do buyers make?

Buying the 87 psi set. The Tymate TM2 4-Set reads to 87 psi, which may be below your tire's pressure.

Is the RVenture 4-Sensor worth it over the Tymate TM3 4-Set?

If you want a repeater and replaceable batteries, yes. The Tymate TM3 4-Set costs far less and reads to 144 psi.

How do I install four sensors?

Screw each sensor onto its valve stem, pair it with the display per the instructions and verify against a gauge. Use the supplied wrenches for locking nuts.

How do I maintain them?

Replace the CR1632 batteries when the display warns, and check sensors for corrosion. Keep solar panels clean.
