GRUNDIG Solar Powered TPMS, 6-Sensor Wireless Tire Pressure Monitor for RVs & Trucks, Up to 217 PSI High Pressure Range, Easy Installation, Waterproof Sensors for Fifth Wheels, Motorhomes, Campers

GRUNDIG: 80 Years of Automotive Engineering & Precision Founded in Germany in 1945, Grundig established a long-standing reputation for precision engineering and technical reliability. The brand officially entered the automotive industry in 1951 with the development of the Autosuper 248, one of the era’s most advanced car radios. Over the decades, our expertise has evolved from pioneering in-car entertainment to engineering specialized mobility solutions that integrate European technical mastery with a global perspective on vehicle safety. Today, this heritage directly informs our TPMS solutions. We apply eighty years of experience in automotive electronics to address the safety needs of modern road travel. By integrating professional-grade components with real-time sensing technology, Grundig Auto provides reliable monitoring systems that ensure consistency and safety for a wide range of vehicles, from daily commuters to long-distance adventure rigs. ABOUT TPMS Beyond Safety: Prevent Accidents & Maximize Fuel Economy. This system goes beyond real-time monitoring to drastically reduce the risk of blowouts and accidents. By instantly alerting you to low tire pressure, it prompts timely re-inflation—maintaining optimal tire footprint, reducing rolling resistance, and saving you significant money on gas during every long haul. Proactive Safety Monitoring & Fuel Optimization. The primary function of this TPMS is to deliver precise, real-time tire data to prevent potential blowouts before they happen. When low pressure is detected, the proactive alert guides drivers to re-inflate tires promptly. This crucial step not only extends tire life but ensures optimal rolling resistance, effectively lowering overall fuel consumption for heavy-duty setups. 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 2.0 to 15.0 Bar (up to 217 PSI). 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. 【Recommended Signal Repeater for Extended Lengths】For motorhomes, 5th wheels, or towing setups exceeding 30 feet in total length, a Signal Repeater is highly recommended. RV chassis and dense metal structures can naturally attenuate radio frequency (RF) signals. The repeater is designed to amplify the signal from the rear tires, ensuring stable, uninterrupted 433.92MHz data transmission to your display monitor, preventing intermittent readings. 【Up to 1-Year Sensor Battery Life】Engineered for heavy-duty applications, our external sensors reliably monitor extreme tire pressures up to 15.0 Bar (217 PSI) while maintaining optimal energy efficiency. Powered by easily replaceable batteries, each sensor delivers up to 12 months of continuous operational life under standard driving conditions. The system display will proactively alert you when a sensor battery runs low. Ⅲ. Purchase Precautions Before placing an order, please carefully confirm whether it is compatible with your model.
