TPMS: Minimising Costs and Environmental Impact
Bridgestone’s patented TPMS system allows rapid deployment of a pressure monitoring solution to an entire fleet with limited vehicle downtime. The solution centrally collects data and informs directly the service partner to make actions needed to keep the fleet running at optimal pressure.
Neil Purves, Solution Business Systems Manager at Bridgestone Europe: “Bridgestone already invests heavily in developing tyres with low rolling resistance and long tyre life. However, ensuring maximum efficiency and durability does not just stop at the design phase. It is essential to maintain correct tyre pressure under varying load, road and temperature conditions in order to ensure maximum safety, efficiency and environmental performance. And that is where our innovative Tyre Pressure Maintenance System comes in.”
Bridgestone’s TPMS helps reduce these hidden environmental and operational costs via a system of sensors installed on existing tyre valves. Each sensor contains a built-in transmitter which sends data to the TPMS gateway via a wireless connection every 6 seconds. Whenever a vehicle fitted with the Tyre Pressure Monitoring System passes through this gate, receivers collect the data and send it to a centralised server via the GPRS network for processing. Web-based fleet management software collates the data and sends automatic maintenance alerts to the relevant fleet manager and service provider whenever the inflation pressure of a specific tyre drops below a pre-defined tolerance level. The under-inflated tyre is specifically identified for the service provider to make a rapid intervention. For smaller fleets, a new Smartphone App used in conjunction with a handheld receiver can give an economical alternative to the gate solution.
With Bridgestone TPMS as part of the fleet service package the fleet can be assured that they are running at optimal pressures.
The Importance of Tyre Pressure
Tyre inflation pressure not only affects rolling resistance but also tyre wear. A tyre with low pressure will consume more fuel and run fewer kilometres before requiring replacement. That reduction in mileage means that more tyres need to be produced, using more raw materials and more energy in the process. Data collected by Bridgestone Europe during fitment of sensors to fleets confirm that on average, 20% of the tyres used by fleets without a controlled pressure monitoring programme run at least 10% below the recommended inflation pressure, of which 5% run at less than 20% of the recommended pressure. In other words, around 1 in 5 tyres in a typical fleet have a significantly negative impact not only on the environment but also on the fleets operational efficiency and thus competitiveness.
Since Bridgestone’s innovative Tyre Pressure Monitoring System was launched in May 2013, over 24,000 sensors have been installed on 36 fleet locations throughout Europe. As such, it is estimated that the system has already resulted in CO2 savings of around 2,000 tonnes, equivalent to 21 fewer trucks on the roads for a full year. TPMS has also succeeded in extending the lifecycle of tyres fitted with the system, equivalent to an extra 210 million kilometres driven, 319 fewer breakdowns and 239 recycled/retreaded casings.
Part of Total Tyre Care by Bridgestone
The Tyre Pressure Monitoring System is part of Total Tyre Care by Bridgestone, a flexible range of complementary truck tyre programmes designed to help fleets keep tight control on tyre-related costs. Total Tyre Care programme consists of 3 pillars: (1) Total Tyre Life, geared around a robust casing built to deliver multiple lives, offering a long first life thanks to superior Bridgestone design features and (multiple) retread lives with the company’s Bandag retread solution. (2) Total Tyre Services, the component that keeps a fleet’s trucks running at maximum efficiency with maintenance, monitoring and assistance services provided by the pan-EU network of Bridgestone partners. (3) Total Tyre Systems, which gives fleets clear visibility of their tyre conditions at all times via Bridgestone’s unique monitoring and tracking tools such as Toolbox and TPMS.
Bridgestone’s Tyre Pressure Monitoring System will be on display at the Bridgestone stand (Hall 16, stand C01) at the 65th IAA Commercial Vehicles International Motor Show in Hanover (Germany), 25th September to 2nd October 2014.
