Outside the tire Sensors made sense to us
Back in 2005 we were looking for a tire pressure sensor system that would integrate into our fleet that was cost effective and user friendly, and that also saves us money. After researching other products we found that the PressurePro would best suit what we wanted in a tire pressure monitoring system. We have been using the PressurePro since 2006 with great success. It has dramatically cut our OTR cost along with increased fuel economy and extending the miles per 32nd with more even tread wear.
We implemented it across our fleet which consists of 70 Kenworth and Peterbilt Tractors. We made the decision to add to our fleet in 2009 and we brought in 45 new tractors. Tri Hi has gone to all wide-based tires which cost more so it’s important we manage the tires better. We considered different TPMS products and chose PressurePro and we’ve been very happy with the product and their service.
Outside the tire sensors made sense to us over the other systems that installed inside the tire. We’re not interested in breaking down tires to install sensors, we don’t want to damage sensors when changing worn tires and we don’t want to break down tires when we rotate tires, too much time and expense. We had a concern about theft of the sensors since they sit on the stem but we’ve never had a sensor stolen in the 3 years we’ve been using the system and they’ve more than paid for themselves.
We found we got longer wear from our tires and our cost to maintain them decreased. Our average, miles per year on steers is now between 135K to 150K (was 90K before use of PressurePro). On drive tires they’d be rotated front to back and flipped on the rim during the year before replaced the following year with about 260K to 325K miles on them. Same on trailers, about 50% of the tires get flipped on the rim and aren’t replaced until they’ve got about 140K to 170K miles. We did no retreading on them during that time. That’s mileage with the PressurePro system on. PressurePro enables our drivers to detect a low tire and take action before we have damage to a tire or a catastrophic failure. A failure OTR cost us $1,200 plus down time and that’s if the driver doesn’t damage the rim. So that’s the performance we see from the PressurePro and yes it makes it easier for the driver. We also have a couple T-660’s, they have just fewer than 200k on them. We just pulled a set of drives on one of our Peterbilt 387’s that had 298K on them with 8/32nd of tread left. We pulled them because the driver had spun one of them cutting the tread or we could still have kept them in service.
With the PressurePro helping to lower the bottom line we can be more cost effective for our customers without sacrificing reliability. I think the PressurePro tire monitoring system is a great tool and would highly recommend it to anyone… pays for itself.
