Tire blowouts remain one of the leading causes of commercial vehicle accidents in Europe and North America. Yet the majority of blowouts are preventable. Underinflation, slow leaks, and heat buildup are responsible for most failures — and all three are detectable well in advance with the right tire pressure monitoring system.

Choosing a TPMS for a commercial vehicle is not the same as fitting sensors to a passenger car. The pressure ranges are different, the wheel configurations are more complex, and the consequences of getting it wrong are significantly higher. This guide walks through what fleet operators, distributors, and OEM buyers need to know before making a decision.

Why Commercial TPMS Is a Different Category

A standard passenger car TPMS operates in the 2–4 BAR range. Most heavy trucks run between 8 and 9 BAR on drive axles, with some applications requiring sensors rated to 15 or even 18 BAR. Using a consumer-grade sensor in a commercial setting is not just inaccurate — it is a safety liability.

Beyond pressure range, commercial vehicles present challenges that simply do not exist in passenger car applications. A long-haul semi with a trailer may have 18 wheels or more. A motorhome towing a vehicle has wheels that the driver cannot see or feel. In these cases, real-time wireless monitoring is not a convenience feature — it is the only reliable method of detection.

Matching the System to the Vehicle

The single most important factor in commercial TPMS selection is matching the sensor specifications to the vehicle type and application. Below is a practical breakdown by vehicle category.

Passenger Cars and Light Commercial Vehicles

Four-wheel vehicles in the 1–8 BAR range are the simplest application. Internal sensors — mounted inside the valve stem — offer a cleaner installation and are less vulnerable to theft or accidental impact. The AN15 series covers this segment with four internal sensors and a pressure range suitable for most vans, pickup trucks, and light commercial applications.

6-Wheel Trucks and Medium-Duty Vehicles

Trucks with dual rear wheels introduce the first real complexity in TPMS installation. Each axle position must be individually monitored, and the dual rear configuration means sensors need to work reliably in close proximity to each other without signal interference. The S04B is engineered for this configuration, covering six wheels at pressures up to 15 BAR.

RVs, Motorhomes, and Travel Trailers

The RV and motorhome segment is one of the fastest-growing applications for aftermarket TPMS in both the US and European markets. Owners often travel long distances on unfamiliar roads, and the towed or towing configuration creates blind spots where a tire can lose pressure for hours without the driver noticing.

The RV01 supports 4, 6, and 8-wheel configurations with a 0.1–8 BAR range, covering everything from compact campers to larger Class A motorhomes. For dealers supplying into the RV and outdoor recreation market, this is a natural add-on product with high perceived value and straightforward installation.

Heavy Trucks and Long-Haul Fleets (8 to 24 Wheels)

At the heavy end of the commercial spectrum, TPMS requirements become significantly more demanding. Sensors must operate reliably at pressures up to 18 BAR, across 8, 12, or even 24 wheel positions. Signal transmission through large steel frames and over long vehicle lengths creates additional engineering challenges.

The S05 is built for 24-wheel heavy truck applications with a pressure range of 0.1–18 BAR. For vehicle lengths where wireless signal strength may be an issue — particularly with long semi-trailer combinations — a signal repeater is included as part of the system configuration to maintain reliable communication between sensors and the cab display.

What Distributors and OEM Buyers Should Evaluate

For distributors sourcing TPMS products, the evaluation framework goes beyond the sensor specifications. Three factors consistently drive buying decisions at the commercial level.

Certification and Compliance

CE and FCC certification are non-negotiable for European and North American markets respectively. In fleet procurement, purchasing managers are often required to document that all safety-related components meet applicable standards. Supplying uncertified products creates liability that most large fleet operators will not accept. All Grundig Motion commercial TPMS products carry CE and FCC certification.

Environmental Durability

Commercial vehicles operate in conditions that passenger cars rarely encounter — extended off-road use, high-pressure washing, sub-zero winters, and desert heat cycles. An IP67 rating ensures the sensors can survive dust ingress and temporary submersion, while an operating temperature range of −40°C to 125°C covers the full range of commercial applications globally.

OEM and White-Label Options

For businesses looking to integrate TPMS into their own branded product lines, OEM and ODM customisation is available across the full truck and fleet TPMS range. Minimum order quantities and lead times vary by product. Contact the Grundig Motion trade team directly to discuss white-label configurations and packaging specifications.

Summary: How to Choose

Start with the vehicle type and wheel count. That determines which product family applies. From there, confirm the pressure range covers your application — particularly important for heavy trucks where standard sensors will not meet the specification. If the vehicle is long enough that wireless signal coverage may be inconsistent, include a repeater in the system configuration.

For distributors, the commercial vehicle TPMS segment offers a reliable, repeat-purchase customer base. Fleet operators who specify a system tend to standardise on it across their whole fleet and reorder sensors as part of routine maintenance. It is a different sales dynamic from consumer accessories — and a more stable one.
