Circulating with over or under pressure tyres is a potential hazard to road safety. But it also penalizes vehicle performance and increases fleet management costs. TPMS is a good solution to start saving.
Tyres to the dock as the main investigated for fatal traffic accidents: researches and studies carried out over the years seem to confirm this. An estimated 11,000 tire-related crashes, for example, cause nearly 200 deaths in the USA each year. That’s according to the National Highway Transportation Safety Administration (NHTSA) - the agency within the U.S. Department of Transportation -, which also credits under-inflated tyres and overloaded vehicles as a major cause of tyre failure.
Because of rising costs, especially for what about fuel, more and more road users - car and truck drivers as well - often neglect regular vehicle maintenance, for what about the tyres too. The correct pressure of tyres is a key component in keeping a high level of safety. It helps to well distribute the weight of the vehicle on the tread pattern. The other way around, when tyre is under- or over-inflated, it loses stability, negatively affecting handling, cornering and stopping. And also, tyre wears unevenly thus. Over-inflation lows the cushioning capability of tyres. So, these become more liable to impacts and abrasions. This fakes the vehicle's performances and also increases centre tread wear. Under-inflation brings excessive flexing of the sidewalls causing overheating and potentially break-up. Beyond, the reduced tyre-road contact contributes to shoulder wear and penalizes handling. Finally, under-inflation is the major cause of tyre blowouts.
It is not only a road safety matter but clearly even also an economic one. Impacts on fleet management can be crucial indeed since both under- and over-inflation can badly and negatively compromise the overall vehicle behaviour and also shorten tyres life quickly anticipating their replacement. To help drivers and fleet managers to better face bad likely occurrences, technology suppliers have developed and introduced on market some solutions such as Automatic Tyre Inflation Systems (ATIS) and Tyre Pressure Monitoring Systems (TPMS). Starting with the model year 2008, all cars, trucks and light vans are required to be equipped with TPMS. The main difference among the two solutions is ATIS automatically works to maintain proper tyre pressure, TPMS keeps under control the air pressure levels reporting any detected problems in real-time to the driver. ATIS and TPMS technologies have proven themselves in some real-world fleet tests, including a long-term study realized by the U.S. Department of Transportation (DoT) between 2008 and 2010. The final results revealed meaningful improvements in fuel economy and in tyre wear. Based on current fuel costs and equipment costs per tractor-trailer unit, the ROI (Return Of Investment) came in under one year.
Studies overall confirm impressive and really crucial savings in terms of safety, fuel consumption, tyre wear and failures, maintenance and replacement costs that can be all achieved simply from the improvement of systems as TPMS. Here because the Tyre Monitoring Systems’ offer today available on the global market has become wider and wider and even also more specialized 'till including also some specific advanced management solutions for TBR (Truck and Bus Radial) and OTR (Off The Road) tyres, such as “Smart4Trucks” and “Smart4Mines” by Aeolus Tyres. Due to wireless connectivity and the most advanced sensor-based technology, these two Ntyre Smart Fleet Systems keep on strict control the fleet tyres’ status, collecting every moment data about inside pressure and temperature, mileage, wear, and so on and referring them to server systems in a wireless communication mode. The smart tyres management systems can not only generate real-time safety warnings but also produce more comprehensive and intelligent data for increasing fleet management efficiency and the overall safety as well. Automatic Conversion Cold Air Pressure system, for example, checks the pressure without waiting for the hot vehicle to cool down reasonable. Integrated microprocessor and non-contact operation guarantee safer operations for controlling tyres' information (Tyre Code & DOT can be recorded in the sensor), pressure (measuring air pressure with traditional way may lead to the problem of valve core cannot be reset) and inflation (check the pressure data from 5 meters away, prevent the injury during the inflation process).
So, the more advanced TMPS and Smart Tyres Management Systems are surely precious to enhance safety, but they are also definitely the tools that can’t miss in the fleet managers' toolbox no more.
