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

Specially engineered for 6-wheel configurations with an industrial-grade monitoring range up to 217 PSI (15.0 Bar):

Heavy-Duty & Super C Motorhomes: Optimized for large-scale motorized builds requiring high-pressure stability, such as Class A Diesel Pushers and Super C rigs built on Freightliner or Spartan chassis.

6-Wheel Class C RVs: Seamlessly monitors dual-rear-wheel setups for popular models like Thor Four Winds, Jayco Greyhawk, and Winnebago Minnie Winnie, providing accurate data even as pressures climb during highway travel.

High-Pressure 5th Wheels & Toy Haulers: The ultimate solution for heavy-duty towables (e.g., Grand Design Momentum, Keystone Montana) equipped with Load Range G, H, or J tires that often exceed the standard 116 PSI limit.

Dually Pickups & Commercial Trucks: Tailored for dual-rear-wheel (DRW) powerhouses including the Ford F-350/F-450, RAM 3500, and Silverado 3500HD, as well as medium-duty commercial vehicles like the Isuzu NPR and Hino 268.

Ⅱ. Product Function

【Ready-to-Use for Heavy-Duty Fleets】Say goodbye to complicated setups. Our TPMS comes pre-configured for heavy-duty applications with a default high-pressure alarm at 116 PSI (8.0 Bar) and a low-pressure alert at 43.5 PSI (3.0 Bar). It is designed to be ready to hit the road straight out of the box, saving professional drivers time and effort. Just mount the sensors and drive with confidence.

【Advanced Solar & Type-C Dual Charging】 Equipped with high-efficiency solar panels and a built-in 500mAh large-capacity battery, the S-04 ensures uninterrupted tire monitoring even on cloudy days or long night drives. It supports Type-C/USB fast charging, providing a reliable power source for all-weather road safety.

【15 Bar/217 PSI Range for Heavy-Duty Vehicles】 Engineered for large vehicles, this system offers an expansive pressure monitoring range from 29 to 217 PSI (2 to 15 Bar). It is the ideal safety solution for heavy-duty commercial trucks, dual-axle RVs, 5th wheels, motorhomes, and buses.

【6-Wheel Real-Time Monitoring with Clock】 The upgraded all-weather, full-viewing angle LCD display shows tire pressure and temperature for 6 wheels simultaneously without glare. Plus, the integrated high-precision digital clock turns your monitor into a comprehensive cockpit command center.

【Smart Vibration-Sensing Auto Start-Stop】 Enjoy hands-free operation with our intelligent sensing technology. The monitor automatically powers on when it detects vehicle vibration and enters power-saving standby mode when stationary for over 10 minutes, significantly extending battery life and device longevity.

【Industrial-Grade IP67 Waterproof Sensors】 The kit includes 6 rugged external sensors designed to thrive in harsh environments. Featuring IP67 waterproof, dust-proof, and anti-corrosion ratings, these sensors can withstand extreme temperatures from -40°C to 125°C, ensuring a stable 433.92MHz signal with zero data loss.
