Tire Wear Tells a Story
When a trailer's tires wear unevenly — cupping, feathering, or wearing faster on one side — the tires usually aren't the actual problem. They're the symptom of something happening upstream in the suspension or alignment.
Common Culprits
- Worn bushings or hangers — allow the axle to shift out of alignment under load, causing dog-tracking and edge wear.
- Weak or leaking air springs — uneven ride height changes how weight is distributed across the axle.
- Bent or damaged axles — even a small bend from a curb hit or pothole changes tracking permanently.
- Out-of-spec alignment — trailers get out of alignment just like tractors do, especially after suspension repairs.
Cupping and feathering patterns actually help us diagnose the cause — feathering usually points to toe misalignment, while cupping often points to worn bushings or shocks not controlling axle movement properly.
Why It's Worth Fixing at the Root
Replacing tires without correcting the underlying suspension issue means you'll be back for new tires again in a fraction of the expected tread life. We check ride height, alignment, and suspension components together, so the fix actually holds.
If you're replacing trailer tires more often than expected, bring the trailer in for a suspension and alignment check before the next set goes on.
