Alignment and rotation protect the most expensive consumable on the car. A wheel pointing slightly away from the direction of travel is scrubbed sideways every meter the car moves, and a set of tires destroyed that way costs considerably more than the alignment would have.
What does my tire wear pattern mean?
Tires record what is wrong, and the pattern identifies which angle is responsible.
- Both shoulders worn with the center intact indicates underinflation, not alignment.
- The center worn with shoulders intact indicates overinflation.
- One shoulder only points at camber.
- Feathered edges across the tread blocks, sharp one way and smooth the other, point attoe.
- Patchy or cupped wear usually means worn dampers rather than geometry.
Checking this takes seconds whenever pressures are checked. A pattern caught early costs analignment; the same pattern caught late costs tires as well.
Wheel Alignment and Tire Rotation: Questions
How often do I need wheel alignment and tire rotation?
Rotate tires at the interval in your owner's manual, often every other oil change, and check your wheel alignment and tire rotation needs after any hard pothole or curb strike.
Can I rotate tires without an alignment?
Yes, but if the tires show uneven wear, fix the alignment first, or the new positions will wear the same way.
What does uneven wear tell me?
Wear on one edge usually points to camber or toe; cupping points to worn suspension parts.
