GRUNDIG: 80 Years of Automotive Engineering & Precision

Since 1945, Grundig has stood for German precision engineering. From the 1951 Autosuper 248 to today, we've evolved from car audio to advanced automotive safety solutions. This heritage drives our TPMS systems: professional-grade components and real-time sensing technology that deliver reliable monitoring for every vehicle.

Ⅰ. Compatible Vehicles

Specifically engineered for multi-axle configurations and high-pressure industrial tires, supporting seamless monitoring for 8 to 12-wheel setups up to 217 PSI (15.0 Bar):

Luxury Class A Diesel Pushers: The ultimate choice for premium, heavy-chassis motorhomes that often feature a tag axle (8 wheels total) and require high-pressure stability for cross-country tours.

Massive 5th Wheel & Toy Haulers: Optimized for triple-axle trailers (e.g., Grand Design Momentum, Keystone Fuzion) and heavy-duty towing combinations that exceed standard tire pressure limits.

Commercial Trucks & Semi-Trailers: Reliable real-time monitoring for commercial fleet vehicles, including dual-rear-wheel (DRW) box trucks and 10-to-12 wheel semi-configurations.

Multi-Axle Boat Trailers: Designed to handle the specialized high-pressure requirements of large boat trailers, ensuring your marine investment is protected against blowouts during long-distance hauls.

Dually Pickups with Gooseneck Trailers: Perfect for heavy-duty setups like a Ford F-450 or RAM 3500 towing large gooseneck trailers, where monitoring the entire 8-to-10 wheel footprint is critical for safety.

Ⅱ. Product Function

【Industrial-Grade Range: Up to 217 PSI】Specifically engineered for the heaviest rigs, the S08 monitors pressures up to 217 PSI (15.0 Bar). It is the ultimate solution for high-load tires (Range G/H/J) found on Class A Diesel Pushers and massive 5th wheels.

【8/12 Wheel Seamless Switching】Versatility for every configuration. Easily switch between 8-wheel and 12-wheel modes to match your specific setup, whether it's a dually pickup towing a large 5th wheel or a full commercial truck with a trailer.

【40-Meter Long Range & Stable Signal】Specifically designed for large vehicles, the system features a powerful transmission range of up to 40 meters (131 feet). Enjoy consistent data syncing with zero packet loss, making it the perfect monitoring solution for long motorhomes, travel trailers, 5th wheels, and towed vehicles.

【High-Precision Core & Zero Latency】Powered by advanced imported chipsets, this system delivers ultra-precise data feedback with zero latency. It monitors tire conditions in real-time with enhanced stability, allowing you to prevent unexpected blowouts and handle emergencies before they happen.

【Intelligent Automatic Start-Stop】Featuring a built-in vibration sensor, the monitor intelligently powers on when it detects vehicle movement and enters a power-saving standby mode when idle. This fully automated system requires no manual operation, significantly extending battery life and ensuring the device is always ready when you are.

【"Four-Proof" Rugged Reliability】Engineered to endure the harshest road conditions. Our sensors feature a Four-Proof design: IP67 Waterproof, Anti-Seismic, Dust-Proof, and Anti-Corrosion. From melting bitumen to freezing mud, these sensors provide 24/7 reliability without failure.

Ⅲ. Purchase Precautions

Before placing an order, please carefully confirm whether it is compatible with your model.

IMPORTANT: ADAPT ALARM SETTINGS BEFORE USE!
The factory default high-pressure alarm for the S08 is set at 145 PSI (10.0 Bar). While this is designed for heavy-duty use, tire requirements for Class A Motorhomes, 5th Wheels, and Commercial Trucks vary significantly.  
To prevent false alerts or delayed warnings, you MUST reset your high and low pressure alarm limits (Supports up to 217 PSI / 15.0 Bar) according to your specific tire manufacturer standards BEFORE installation. Ensure your safety thresholds are correctly calibrated for a quiet and secure journey across long distances.
