Tire Pressure Monitoring Systems

Most over-the-road customers are focused on optimizing their fuel economy. But an often overlooked way to ensure optimum fuel economy is by specifying a Tire Pressure Monitoring System (TPMS). Not only do properly inflated tires help fuel economy, but they also keep drivers safe by alerting them to low pressure situations that could cause an accident.

We recently released our next generation TPMS. Thanks to optimization in the architecture of the system, the list price has decreased significantly. Plus, the system will now display tire pressures as soon as the truck is turned on. Previously, the system needed a few minutes to populate all the measurements in the dash.

Installing a TPMS is an easy way to keep an eye on tire pressure. If a tire is underinflated, the system will display an alert in the driver info unit. A tire that is underinflated by even 10 PSI can result in a fuel economy loss of up to 1%. Imagine a driver running on under inflated tires for a few days, and that can add up quickly!

Aside from fuel economy, there are several other reasons why customers should consider specifying TPMS. Properly inflated tires offer several additional cost savings benefits:

  • Longer tread life
  • Longer tire carcass life and additional retreads
  • Less vehicle downtime
  • Improved vehicle and driver safety

When having this discussion with your customer, it is important to take into consideration the overall picture. Talk to them about what downtime they see due to tire-related road calls. Walk them through the benefits of knowing, at a glance, if they have any possible issues with their tire inflation. It’s not just fuel economy savings; you can help them build the case to justify the investment in a TPMS system.
