New Lightweight Wheel Cover Targets Simpler Aero Gains [Watch]
Watch to learn how Deflecktor's new wheel cover design is taking a simpler approach to aerodynamics, with an eye toward making it more practical for both trucks and trailers.
April 13, 2026
Heavy Duty Trucking recently caught up with Jon Fleck of Deflector to take a closer look at the company’s new Hubbub aerodynamic wheel cover.
Designed for both tractors and trailers, the Hubbub wheel cover takes a simplified approach to wheel aerodynamics. The lightweight design—just 28 ounces—uses a wire-frame structure with adjustable straps, allowing it to mount on either steel or aluminum wheels using a single part number.
The focus is also on cost, with the aim of making wheel covers a more practical aero option for trailers as well as tractors.
In this video, Fleck walks through the design and explains what sets it apart from previous wheel-cover approaches.
