A wheel alignment maximizes the life of your tires and prevents your car from veering to the right or left when driving on a straight, level road.Checked 2026-08-12
Wheel alignment and tire wear
The wheel angles that decide how evenly a tire wears, and the wear patterns that reveal them.
Also called: alignment · camber · toe · tire wear pattern
What it means
Definition
Alignment sets the angles at which each wheel meets the road — camber, toe and caster. NHTSA states that a wheel alignment maximizes the life of your tires and prevents your car from veering to the right or left when driving on a straight, level road. When an angle is out of specification the tread wears unevenly, and the pattern points back at the angle: Hyundai's tire maintenance bulletin states that tires with wear concentrated on the inner or outer tread indicate that the toe or camber alignment angle is out of specification.
Why a buyer cares
What it changes
Tread wear is visible without tools and without the seller's cooperation. Uneven wear on an otherwise tidy car is a question about alignment or about worn suspension parts.
In practice
Where you meet it
On the tires themselves, on a tire shop's inspection sheet, and on an alignment printout listing camber, caster and toe.
Two things that look alike
Not the same as
Balancing corrects weight distribution around the wheel and tire; alignment sets angles.
