Enhanced Tire Pressure Monitoring for Fleets: EVA PRO and Modern TPMS

In recent years, transport companies faced growing costs as spare parts, including tires, rose in price and revenues tightened. A budget tire with a 22.5 inch diameter can cost around 30,000 rubles, while premium brands may reach as high as 90,000 rubles per tire for certain models. To stretch the life of tires and cut expenses, many fleet managers and foremen are turning to smarter tire maintenance strategies, with tire pressure management at the forefront.

One factor that directly affects tire mileage is proper pressure. Unlike visible human errors such as curb scrapes or aggressive cornering that wear tires quickly, pressure is a controllable variable. The main goal is to minimize trips with low tire pressure because underinflation not only shortens tire life but also increases rolling resistance and fuel consumption. For fleets with hundreds of vehicles, including multi-axle and dual-tire configurations, adhering to strict tire pressure standards can save millions of rubles each year.

Traditionally, quick pressure checks relied on a boot tap in the field, a method adequate for a few tires on a light vehicle. For large-capacity mainline fleets, automated pressure systems with wheel sensors have shown greater effectiveness. However, manufacturers of tire pressure monitoring systems TPMS offer varying approaches to driver alerts.

Most Western TPMS suppliers rely on a warning light on the instrument panel. The idea is simple: when a fault arises, drivers are instructed to visit service personnel promptly. Enhanced systems, though, push for early detection and continuous monitoring rather than a single warning after a problem grows serious. This is where Acceptum-Engineering from Krasnoyarsk steps in with a more advanced approach that surpasses standard replacements.

The EVA PRO hardware and software system monitors not only inside-wheel pressure and temperature but also the ambient temperature. This broader view helps detect slow leaks or small punctures even when tire temperature rises during operation, which can temporarily skew pressure readings due to gas expansion. In many other TPMS setups, the indicator might simply turn off after a spike in temperature, leaving a latent issue unaddressed. The consequence is obvious: late detection can lead to a tire failure on the road.

Display accurate pressure and temperature readings

The EVA PRO system presents real-time pressure and temperature data for each wheel on a dedicated display included in the kit. The processor continually computes a recommended pressure and cross-checks data from wheels on the same axle. If a wheel deviates from the recommended value or if there is a significant pressure difference between twin tires on neighboring axles, the corresponding wheel is highlighted in red on a wheel diagram. When a substantial deviation occurs, the entire wheel group glows red, drawing immediate attention. A text alert and audible alarm accompany the visual cue. The alarm stops only after the tire is inflated to the recommended pressure and repairs are completed.

Thus, ignoring a problem is not possible. The system not only streams all data to a fleet manager’s account but also ranks the vehicles by urgency and tire condition. Leading the list are trucks with drivers who show less concern for fuel efficiency and tire wear. These features together build a comprehensive picture of vehicle health and usage patterns.

Our fleet operates grain transport in Siberia. It comprises about two dozen two-axle dump-trailer-grain units and tractors like Scania and Volvo. EVA PRO has been in use for over two years, initially implemented on seven roadtrains with twelve wheel modules per linkage, plus monitors and main controls. The results were clear: timely detection of pressure drops helped avoid tire destruction. Plans are to equip additional roadtrains with the system in the near future.

Internal placement of wheel sensors shielded against water, dirt, and other elements stands out as a reliable choice. During tire changes, sensors remain undamaged within the rim recess. The latest EVA PRO kits come with improved wheel sensors and flexible antennas that resist accidental tire inflation better than older models.

Beyond protecting a tire worth thirty to forty thousand rubles from abrupt failure, the system also reduces delivery delays. With EVA PRO, drivers can see a pressure drop on the monitor and proceed to the nearest tire service before more serious damage occurs. The temperature display also helps identify malfunctions such as brake overheating or hub bearing issues, enabling proactive maintenance and quicker repairs.

Six long-haul tractors and refrigerated trailers with dual 17.5-inch wheels make traditional tire checks unwieldy. The inner wheel valve is harder to access, and drivers may not perform frequent checks. The solution was to install an automated TPMS from Acceptum-Engineering. The EVA PRO kit was first trialed on one roadtrain more than three years ago; its success led to expanding to five of six roadtrains. On 22.5-inch wheels, sensors mounted in the wheels and attached to the discs via clamps work well, while 17.5-inch low-loader wheels require external sensor mounting on the valve stems.

The system operates reliably, with battery life remaining strong and minimal component replacements. When minor malfunctions occur, technicians from the manufacturer’s service team provide support. The continuous monitoring has saved several tires by detecting punctures early. A red warning on the cab monitor shows which wheel is losing pressure, prompting inspection. If damage is found, the vehicle is taken to a tire shop for diagnosis and repair. The temperature monitoring feature is also useful for brakes and hub bearing health insights, even predicting potential brake wear before components fail.

About Acceptum-Engineering

The Krasnoyarsk-based Acceptum-Engineering company, established in 2015, began developing a TPMS with a robust sensor platform. A proof-of-concept wheel module featuring both pressure and temperature sensors was tested across full road trains without extra radio amplifiers. By 2017, the system was installed on Volvo FMX dump trucks used in mining operations. Over the following years, EVA PRO matured, with many fleets adopting it by 2019 and the project joining the Skolkovo Innovation Center. By late 2020, second-generation hardware and software had entered serial production.

Evolution of sensors for 2017-2018

References and milestones are part of Acceptum-Engineering’s journey in tire protection technology. The EVA PRO system emphasizes quick alerts, reliable data, and actionable insights for fleet managers seeking to reduce downtime and extend tire life. The project has been marked by continuous improvement in sensors, mounting options, and service support, ensuring compatibility with diverse vehicle configurations and operating conditions.
