Tire Wear Patterns
Identify common semi truck tire wear patterns and the first checks to make before the problem gets expensive.
Truck Tire Wear Patterns
Wear patterns are clues. Name the specific pattern first — then check the pressure, load, alignment, suspension, or wheel-end issue behind it. Rotation is a tool for managing wear, not a fix for mechanical causes.
Field Use
A tire rotated away from a problem axle hides the cause. Record position, tread depth at each rib separately, and the first mechanical checks before moving it. The pattern tells you where to look: alignment for feathering and one-side, suspension for cupping, pressure for center or both-shoulder edge wear.
Quick Checks
- Measure inner, center, and outer ribs separately — the lowest reading is what matters.
- Photograph irregular wear before rotation.
- Check pressure before investigating alignment or suspension.
- Inspect the axle and suspension, not only the tire.
- Diagnose the cause before rotating a tire away from a problem position.
Center Wear
What center tread wear looks like, common causes, first checks, and when to get a truck tire inspected.
Edge Wear
How to inspect edge wear on semi truck tires and separate pressure, load, alignment, and scrub causes.
Cupping Wear
Cupping or scalloped tire wear explained with common causes and inspection priorities.
Feathering Wear
How to recognize feathered tire wear and what alignment checks usually come next.
Heel-Toe Wear
Heel-toe wear explained for semi truck drive and trailer positions, including rotation and suspension checks.
Irregular Trailer Tire Wear
Trailer tire wear patterns caused by scrub, loading, alignment, pressure, and long parking periods.
Tire Rotation
When and why to rotate semi truck tires, which positions can be rotated, common rotation patterns, and when rotation is not the right answer.
One-Side Tire Wear
Diagnose single-shoulder tire wear on semi trucks — causes include camber, toe, scrub, and suspension lean.
Diagonal Tire Wear
Diagonal tread wear patterns on truck tires — causes, inspection steps, and how to distinguish from feathering.
Flat Spotting
How flat spots form on semi truck tires, when they drive out, and when to remove the tire.
River Wear
River channel wear — where tread grooves deepen faster than surrounding ribs — causes, inspection, and removal decisions.
Irregular Rib Wear
What causes one tread rib on a truck tire to wear faster than adjacent ribs, and how to investigate the cause.
Dual Tire Mismatch Wear
Wear patterns caused by mismatched tires in a dual assembly — size, tread depth, or brand differences forcing one tire to drag.
Inflation-Related Wear
How tire inflation — too high, too low, or mismatched between duals — produces specific wear patterns on semi truck tires.
Alignment-Related Wear
How alignment angles — toe, camber, and axle tracking — produce specific tire wear patterns on semi trucks.
Suspension-Related Tire Wear
How worn or damaged suspension components produce cupping, irregular wear, and accelerated tread loss on truck tires.
Steer Tire Irregular Wear
Irregular wear patterns specific to semi truck steer tires — causes, inspection priority, and when to escalate immediately.
