GRUNDIG RV01 TPMS, 116 PSI, commutable entre les modes 4/6/8 roues, écran HD de 5,0", portée de 40 m

Yes. This system is designed for a wide range of vehicles with 4, 6, or 8 wheels. It is precision-engineered for Class B/C Motorhomes (like Sprinter or Transit builds), Travel Trailers (such as Airstream or Jayco), and heavy-duty pickups (Ford F-Series, RAM, etc.). As long as your cold tyre pressure is under 116 PSI (8.0 Bar), this system is a perfect fit.

Absolutely. You can easily switch the monitor to 8-wheel mode to cover your tow vehicle and a dual or triple-axle trailer simultaneously. For setups exceeding 10 
meters in length, we recommend the version with a Signal Repeater to ensure 100% signal stability.

While our system has a powerful 40-meter (131ft) open-air range, the dense metal frame and aluminum skin of many RVs can block radio signals. If your total setup (Truck + Trailer) is longer than 10 meters, a signal booster ensures you never experience "signal dropouts" or delayed readings from your rear tyres.

Install 1 Signal Booster for distances over 5m (16ft), 2 over 15m (49ft), and +1 for each trailer towed to ensure optimal coverage.

This is usually because the factory default alarm is set for standard cars (approx. 40 PSI). Since RV tyres run at much higher pressures, you simply need to go into the settings and manually adjust your High/Low pressure thresholds to match your tyre's specs. Once set, the beeping will stop.

The monitor features Intelligent Start-Stop. It uses a vibration sensor to wake up instantly when you start driving and enters a power-saving standby mode after 10 minutes of inactivity. You don't need to manually turn it on or off every day.

Each sensor uses a high-capacity CR1632 battery that lasts approximately 12 months under standard driving conditions. They are easily replaceable by the user—no need to buy a whole new sensor when the battery runs low.

Yes. The sensors are IP67 waterproof and rated for structural temperatures ranging from -40°F to 257°F (-40°C to 125°C). 

This is completely normal. The pre-displayed readings are residual test data from our quality control checks at the factory. Once you install the sensors on your tyre valves, the real-time data will automatically overwrite these values.

You can easily change the pressure units by following these steps:
1. In standby mode, press and hold the Center Settings Button for 3 seconds to enter the menu.
2. Short press the Center Button until PSI flashes on the screen.
3. Use the Up/Down Buttons to toggle and select kPa.
4. Press the Center Button once more to confirm and save your setting.

That is a great question, but there is a major technical difference between factory systems and a dedicated heavy-duty setup:

• Indirect vs. Direct Monitoring: Most standard factory vehicles use Indirect TPMS, which doesn't actually measure air pressure. Instead, it uses your car's ABS wheel-speed sensors to estimate if a tyre is flat. It will not show you real-time PSI numbers or critical temperature changes on your dashboard.
• The RV & Trailer Blind Spot: Factory TPMS is strictly designed for the 4 tyres of your solo vehicle. When you hook up an RV, travel trailer, or fifth wheel, your factory dashboard cannot monitor those towed tyres.

Our direct TPMS system gives you real-time, sensor-to-screen precision for both your towing vehicle and your trailer simultaneously, catching dangerous pressure fluctuations before they escalate.

You are absolutely correct that tyre age, wear, and structural damage are the leading causes of highway blowouts. Regular tyre replacement (every 6–7 years) and visual checks are absolutely essential.

However, a TPMS is not a replacement for maintenance—it is your second pair of eyes on the highway. Even brand-new tyres can run over a stray nail, suffer a slow leak, or experience severe internal friction.

While driving, your eyes and common sense cannot detect:

• A slow, silent leak that drops your PSI over 50 miles, overheating the tyre wall.
• A sudden temperature spike caused by a sticking brake caliper or bearing failure.
• Rapid decompression before the vehicle begins to fish-tail.

Our TPMS catches these invisible, real-time metrics instantly, giving you the critical minutes you need to pull over safely before a compromised tyre catastrophically blows out.

This is completely normal and usually depends on the installation sequence. To ensure instant pairing, always power on your monitor before screwing the sensors onto your tyre valves.

If you installed the sensors while the monitor was still turned off, the system will enter its standard background syncing cycle. It may take 10 to 15 minutes of waiting (or a short drive) for the monitor to capture the signal and display the correct, updated tyre pressure and temperature.

If you want an instant sync, simply unscrew the sensors, turn on your monitor first, and then screw the sensors back on.

Place the monitor on your dashboard within 1 meter of your driving seat and adjust the angle to face you directly. This ensures optimal screen visibility and quick, glanceable readability without taking your eyes off the road.

This usually happens if the sensors are installed while the monitor is powered off. Always power on the monitor before installing the sensors for instant pairing. If installed while off, it may take up to 10 minutes to sync and display accurate real-time readings.
