Tire Wearing on One Edge
What inner or outer edge tire wear says about alignment, suspension, and tire pressure.
Quick answer
One-edge tire wear often points to alignment angles, worn suspension parts, underinflation, or hard driving patterns.
Most likely causes
- Camber or toe alignment issue
- Worn ball joint or bushing
- Underinflation
- Bent suspension part
- Repeated hard cornering
Basic driver checks
- Compare inner and outer edges.
- Check tire pressure cold.
- Look for feathering across tread.
- Review recent pothole or curb impacts.
DIY diagnostic path
- Do not align a car with loose suspension parts.
- Rotate tires only if they are safe.
- Measure tread depth across the tire.
- Inspect for cords or cracking.
Common mistakes
- Buying tires without fixing alignment
- Ignoring visible cords
- Assuming pressure alone caused severe edge wear
What to tell the mechanic
Ask for tire condition, suspension looseness check, and alignment readings before and after adjustment.
