Costly Underinflation

In a study conducted by the TMC, the average fleet loses at least $750 per tractor-trailer each year because of underinflated tires.It also showed that a fleet with a consistent problem of underinflated tires required 12% more new tires and 10% more retreads, along with a .6% fuel loss.

Tire Punctures

Trailers equipped with tire inflation systems will overcome small leaks normally attributed to road hazards, such as nails or small metallic debris. Without a tire inflation system, these leaks would result in an abnormal pressure drop or a “run-flat” tire.

Both situations create a hazardous condition which can lead to blowouts, breakdowns, costly repairs, and unanticipated delays in delivery. A tire inflation system will supply air from the onboard compressor to the leaking tire to keep it inflated during operation. Optional warning lights will alert drivers that they have a tire with a leak.

Once the trailer is returned to the terminal or maintenance facility, the leaking tire can quickly be isolated and repaired. This prevents damage to the casing, tread, or in the event of a blow-out, to other vehicles on the road.

With these concerns along with sky-rocketing costs to maintain and replace tires, tire inflation systems are becoming more and more popular with fleet managers.
