FlowBelow’s Wheel Covers with easy air access save time, money and eliminate pretrip hassle

FlowBelow Aero, Inc., the leader in tractor-trailer aerodynamics, announced its new fuel-saving Wheel Covers with Easy Air Access, an innovative upgrade that addresses a long-standing tire pressure monitoring and maintenance challenge for commercial fleets. The product will be on display to the industry for the first time in the FlowBelow booth # 1329, at TMC’s Annual Meeting & Transportation Technology Exhibition, March 16-19, 2026 in Nashville, Tenn.

Even without wheel covers, physically checking inner and outer tire pressures often requires stooping, kneeling and straining to access cumbersome valve stems, sometimes lodged deep inside wheel rims. With both inflation valves ergonomically located in the center surface of FlowBelow’s new wheel covers, drivers and technicians can check tire pressure and inflate tires in seconds, without kneeling or removing wheel covers, eliminating a common excuse for skipping critical pre-trip inspections.

“Our wheel covers are very easy to take on and off, but our Easy Air Access version makes it safer and faster to check tire pressure with wheel covers than without them,” said Katie Breitschopf, executive vice president of business operations for FlowBelow. “We are pleased to have engineered an aerodynamic product that makes it easier for drivers and technicians to maintain proper tire pressures.”

How It Works

Wheel Covers with Easy Air Access extend the valve stems for both inner and outer tires and route them through the center ring of FlowBelow’s aerodynamic wheel cover. The configuration puts both inflation valves within easy reach, between 20 and 22 inches (50.8 to 55.9 cm) from the ground.

FlowBelow engineers partnered with Pressure Systems International (P.S.I.), a leader in tire management systems for commercial vehicles, to develop and supply the air line components required for the Easy Air Access system. Optional auxiliary valves allow for installation of tire pressure monitoring systems, and FlowBelow is offering P.S.I.’s TireView LIVE TPMS as an additional upgrade.

Impact on Fleet Operations

Market feedback drove development of the solution, with fleets identifying pre-trip efficiency as a key objective. The redesign addresses multiple fleet priorities simultaneously: saving time, enhancing driver satisfaction, encouraging tire maintenance compliance, improving fuel economy and advancing worker safety.

Properly inflated tires are essential for fuel efficiency, yet drivers often skip already tedious pressure checks when wheel covers add extra steps to their routine. By streamlining the process, FlowBelow’s Wheel Covers with Easy Air Access make tire pressure monitoring and maintenance easier than ever while helping fleets realize the full fuel-saving potential of aerodynamic wheel covers.

“Our team of engineers focuses on new product development to help fleets save fuel,” said Josh Butler, president and chief technology officer of FlowBelow. “If upgrading existing products will enable more customers to take advantage of a proven technology like wheel covers while making monitoring tire pressure easier, we’re happy to work on innovative approaches to meet their needs.”

FlowBelow wheel covers save a proven 1.74 percent in fuel when installed on both tractor and trailer, according to track testing performed by MVT Solutions. That translates to approximately 2.16 gallons of fuel saved for every 1,000 miles driven. Wheel Covers with Easy Air Access have undergone 12 months of successful, real-world fleet testing, with close monitoring made possible by P.S.I.’s TireView LIVE telematics product.

Availability and Options

Wheel Covers with Easy Air Access are available for purchase directly from FlowBelow, or can be specified through any mod-center for installation on new truck builds. Easy Air Access components may be retrofitted to wheel covers already on a vehicle, or fleets can purchase complete wheel cover kits with integrated Easy Air Access and optional TPMS systems.

The product will be demonstrated at a press conference in the P.S.I. booth #2015 at TMC’s Annual Meeting & Transportation Technology Exhibition, March 16-19, 2026. The new wheel covers will also be on display in FlowBelow’s booth #1329. For more information or to schedule a demonstration, visit www.flowbelow.com.
