Fleet TPMS

Why Monitoring Tire Pressures Matter To Your Fleet

The reasons for having a truck tire pressure monitoring system are simple: effectively managing the costs for tires, including repair and maintenance costs have never been more important for fleets.

In addition, missing a delivery deadline costs money and damages reputations. But the consequences of tire failure can be much more severe than missing a deadline - accidents, repairs, injuries and worse can result from reduced handling, longer breaking distances and blowouts.

The FMCSA has reported the following statistics related to tire pressures on tractors/trucks and trailers:

  • Only 46% of all tractor tires and 38% of all trailer tires inspected during a 2003 study were within +/1- 5 psi of the target pressure
  • About 1 out of 5 tractors/trucks is operating with 1 or more tires underinflated by at least 20 psi
  • Nearly 3.5% of all tractors/trucks operate with 4 or more tires underinflated by at least 20 psi
  • Approximately 3% of all trailers and more than 3% of all tractors/trucks are operating with at least 1 tire underinflated by 50 psi or more

The Doran 360™ tire pressure monitoring systems allows you to accurately check the tire pressure on your trucks and trailers with the push of a button on the display in the cab. In addition, TPMS integration projects with telematics providers provide the capability for low pressure alerts to be sent out via e-mail/text message and also provide tire pressure reporting capabilities to help understand and manage your problem tires.

Minimizing Costs With The Doran 360™ Tire Pressure Monitoring Systems

In general, tires lose air pressure at about one pound per month. Drivers usually notice this gradual air loss too late and serious consequences can arise. Without a Doran 360™ tire pressure monitoring system, this drop in pressure can be difficult to test, as a visual inspection does not indicate if the tires are properly inflated. In addition, it is time consuming to check each tire manually with a gauge and the gauges are not always calibrated properly. The Doran 360™ tire pressure monitoring systems for trucks accurately identify these slow leaks and warn the driver long before the problem causes irreversible damage. With a Doran 360 tire pressure monitoring system, the driver is alerted to a tire pressure problem and can react immediately. This will help to maximize tire life and fuel efficiency along with minimizing the costs that are caused from an accident or sitting idle. Obviously, improper tire inflation significantly impacts your operational costs and a Doran 360™ tire pressure monitoring system can help to improve the bottom line profit for your fleet.

It is common knowledge in the trucking industry that maintaining proper tire pressures will help to optimize tire life and can have a positive impact on fuel economy. Reducing tire pressure issues not only improves safety and prevents expensive repairs but also helps to extend the life of tires and reduce fuel costs:

  • It has been reported that 10% under inflation will shorten tread life by 9% to 16% which can equate to a minimum of $25 per tire in unnecessary and preventable additional costs
  • The Department of Transportation estimates that 4 million gallons of fuel per day are wasted (over 1.3 billion per year) because of low tire pressure

Tire pressure monitoring, combined with proper inflation, can prevent many instances of tire failure.

  • More than 85% of tire-induced breakdowns are due to undetected slow leaks and only the remaining 15% are attributed to sudden tire damage.
  • National Highway Safety Studies indicate at least 50% of the commercial trucks on the road are running on under-inflated tires.

Hidden Benefits of the Doran 360 Tire Pressure Monitoring System for Fleets

However, with more fleets adopting and installing tire pressure monitoring systems on trucks and trailers, some of the hidden benefits associated with monitoring and maintaining tire pressures based on tire manufacturers’ recommended pressures have started to be revealed. This exposure is delivering unanticipated cost savings to fleets and is generating a positive impact to the bottom line.

Through Doran’s field trials and implementation of the 360 TPMS with a wide variety of fleets across the country, we have been exposed to four “hidden” benefits related to tire pressure monitoring systems:

Reduction in Road Side Tire Calls

  • It is quite obvious that pre-trip inspections can identify a tire that has low pressure so that it can be addressed appropriately before starting the trip. Consistently maintaining proper tire inflation pressures minimizes side wall flexing and uneven tread wear that can lead to a catastrophic tire failure. When the truck ignition is turned on, the driver can immediately see the current tire pressure in each wheel location and any tire experiencing a low pressure event can be addressed following the fleet’s recommended procedures.
  • In addition to receiving digital tire pressure updates, utilizing a tire pressure monitoring system allows the driver to have access to real-time low pressure related alarms while on the road. A majority of the fleets that Doran has worked with have indicated that providing drivers with a visual and audible alert when a tire falls below a low pressure threshold has helped them to reduce costly delays and expensive road side tire calls from tire blow outs.
  • In situations where road debris punctures a tire, the Doran 360™ TPMS also has a unique FastLeak™ alarm that provides an additional level of early warning protection when tire pressure rapidly falls by 4.5psi in less than 16 seconds.

Saved Casings

  • Fleets that have implemented Doran tire pressure monitoring systems have improved the overall condition of their tire casings and significantly increased the number of these casings that can be used in retreads. This provides another opportunity to reduce and control tire costs.

Improved Driver Awareness and Safety

  • By providing continuous real-time tire pressure data and alarms for low pressure, drivers become more aware of the issues associated with driving on underinflated tires. Despite a sometimes hesitant, “big brother” initial response from drivers to the acceptance of another monitoring/performance device on the truck, a large percentage of Doran’s fleet customers and their drivers have experienced a high satisfaction level with the 360™ TPMS and an overall sense of driving a safer vehicle with properly inflated tires.

Decrease in Excessive Heat Issues

  • Another side benefit of tire pressure monitoring is the capability to transmit temperature data and alarms. “High temperature” alarms can identify a tire that is over-heating, a hanging break, seized bearing or other wheel-end problems. The stand-alone Doran 360™ TPMS includes a high temperature alarm triggered when air temperature reaches 175°F and telematics providers that have integrated with tire pressure monitoring systems often offer a high temperature alarm.
