Accuride Unveils Anticorrosion Aluminum Wheel Coating
Coating Targets Filiform Corrosion, Truck Downtime
Key Takeaways:
- Accuride unveiled its ProShield XGT aluminum wheel anticorrosion coating on March 15 at TMC’s 2026 Annual Meeting.
- The coating aims to combat filiform corrosion and offers resistance to chemicals and heat, which Accuride executives said will extend wheel life and reduce downtime.
- Accuride plans public availability in the second quarter of 2026, pending OEM adoption and patent approval.
NASHVILLE, Tenn. — Accuride on March 15 unveiled an aluminum wheel anticorrosion coating, , that is intended to combat filiform corrosion, which decreases wheel lifespan and increases truck downtime.
Livonia, Mich.-based Accuride intends to make wheels with the surface protection coating publicly available in the second quarter of 2026, the wheel manufacturer said at a briefing during the Technology & Maintenance Council’s 2026 Annual Meeting and Transportation Technology Exhibition.
Availability for wheels on new trucks and trailers will vary by original equipment manufacturer, based on compliance with their requirements.
“Filiform corrosion is that sneaky, threadlike corrosion that forms under organic coatings. So when … you get a chip, a scratch, it goes underneath the metal and then warm, humid air hits it. Think of it as like the ninja of corrosion. It’s quiet, fast, but it always seems to sneak up on you when you least expect it,” Accuride Senior Vice President Sales Jayne Orr said during the briefing.
“Accuride set out on a mission — create a wheel technology so easy to clean, so durable and so tough that filiform corrosion wouldn’t just struggle, it would give up,” Orr said. “We wanted something that could handle the worst road salts, the most aggressive debris, every chemical known to torment a wheel, and do it all with a finish that lasts the life of the vehicle.”
ProShield XGT offers a surface resistant to chips and other mechanical threats; gloss retention up to 400 degrees Fahrenheit; and resistance to chemical threats, such as acids, bases, oils, fuels, brake fluid and road salts.
The coating also incorporates a hydrophobic surface designed to repel water, oil and contaminants. Orr said Accuride had to design a new glue for identification stickers as a result.
Fleet trials have been underway since April 2025. Production will take place at Accuride’s Erie, Pa., manufacturing facility. The coating does not need refreshing.
“It’s rare that you get to say we reinvented the wheel, but we actually reinvented the wheel coating,” Orr said.
If the patent is approved, the coating could have other uses for rolling stock or elsewhere, she said.
