Impactful CVSA Change Validates Use of Automatic Tire Inflation Systems to Reduce Tire Blowouts

On April 1, the Commercial Vehicle Safety Alliance (CVSA) made an impactful change, which significantly reduces the likelihood of an Out-of-Service Criteria violation for trucks and trailers equipped with automatic tire inflation systems (ATIS). CVSA adopted an amendment to the North American Standard OOSC which allows tires that have a noticeable leak in the tread area to remain in service if they are equipped with an ATIS that maintains the inflation pressure greater than 50% of the maximum inflation pressure on the tire sidewall. The amendment is in Part 11, Item 12 – Tires in the CVSA 2024 OOSC.

Understanding the Amendment

So why was the Amendment adopted? According to CVSA rationale, with the increase in automatic tire inflation systems (ATIS) and the impact they have on the reduction of tire blowouts, the OOSC will differentiate between leaks in the tread area of a tire equipped with ATIS versus a tire without ATIS. If, at any time throughout the inspection, the tire is checked for pressure and the tire is found to be 50% or less of the maximum inflation on the sidewall of the tire, the vehicle will be placed OOS. Allowing an ATIS-equipped vehicle to travel to a safe location (next dispatch) with a small puncture in the tread area of the tire reduces the potential for rear-end collisions or other roadside incidents without affecting the safe operation of the vehicle.

In other words, non-steering tires with a leak in the tread area are no longer considered an OOSC violation as long as they have an ATIS like Aperia’s Halo Tire Inflator® providing the tire with air pressure above 50% of the rating recorded on the tire’s sidewall. The updated ruling reflects how ATIS technology is designed to increase safety not only for drivers but others sharing the road. With the advanced alerts from the system, drivers are able to drive to a safe location to repair or replace their tire.

Impact on Inspection Protocol

“Having a safety alliance like CVSA recognize the positive impact that our Halo ATIS has on the reduction of blowouts and roadside incidents demonstrates the commitment Aperia has in improving safety while delivering a positive financial return for our fleets,” said Ralph Dimenna, Chief Commercial Officer at Aperia Technologies.

Dimenna continued, “Several fleets at the Truckload Carriers Association (TCA) meeting publicly spoke last month about the need to continually reinforce a culture of safety through education, training, technology.”

CVSA inspections aim to ensure commercial vehicles operate safely and are designed to be robust in assessing vehicle maintenance and driver operations. Tires have repeatedly topped the list as a top safety violation for these random inspections.

Technology Driving Safety

Halo Tire Inflator, a proven, self-powered ATIS for tractor-drive tires, uses the wheel’s rotation to maintain optimal tire pressure. This technology is designed to address this top safety issue. Halo resolves more than 90% of tire health issues and delivers a rapid ROI through enhanced fuel economy and tire life. Aperia’s Halo Tire Inflator® pays for itself in the first year and lasts for the life of your truck so you keep saving for years after. 

Aperia didn’t stop with the Halo Tire Inflator but has recently launched Halo Connect for Trucks and Trailers as well as its latest connected technology introduction, Halo Connect i3™ for medium- and heavy-duty trucks and trailers. The comprehensive smart solution, Halo Connect i3, goes beyond ATIS and tire pressure monitoring system (TPMS) offerings, allowing fleets to optimize efficiency and maximize operational uptime with integrated pressure sensing, remote pressure set point adjustment, configurable alerts, and customized inflation settings. Equipped with Bluetooth, RF, CAN, GPS, and LTE connectivity, Halo Connect i3 allows two-way communication, seamlessly integrating with other vehicle devices and fleet management systems, enabling comprehensive monitoring, adjustment, and control.

Promoting Best Practices for Compliance

Aperia has been involved in helping fleets across the nation avoid CVSA inspection violations through Best Practices for Avoiding CVSA Violations, published in Fleet Maintenance magazine. Best practices provide fleets with strategies to help ensure that they have a clean safety record.

It’s important to note that CVSA information is available on the CVSA Out-of-Service Criteria (Version 5.0.0) app.
