THE GRUNDIG TPMS BUYING GUIDE
From a six-wheel truck to a multi-trailer fleet, the right tire pressure monitoring system depends on wheel count, tire pressure, sensor style and how far you need to expand.
Compare the lineup ↓Research-based guide using manufacturer-published information. We have not personally tested these systems.
Grundig's TPMS range spans standard-pressure RV systems, high-pressure six-wheel setups and expandable monitors for larger rigs. We’ve grouped the product pages by use case and linked the focused S04/S08 comparison below. Confirm the cold tire pressure on your vehicle placard or tire documentation before choosing a system.
START WITH YOUR SETUP
Start with the RV TPMS/RV01 or Caravan TPMS, then compare external versus internal sensors.
Start with the S04. Compare its external kit with the internal-sensor version if installation style matters.
Start with the S08 and verify wheel count and sensor pressure rating in the selected package.
Compare the 550S, which scales from 6 to 36 wheels, and confirm the exact sensor kit and repeater needs.
Pressure limits and wheel counts reflect manufacturer listings; kit options can differ. Prices are indicative listing prices where available, not guaranteed checkout prices.
