Alignment, in one sentence
Alignment adjusts the angles at which your tires meet the road. When the angles are off, the car pulls to one side, the steering wheel sits crooked when going straight, and the tires wear unevenly across their tread.
Balancing, in one sentence
Balancing distributes weight evenly around each wheel and tire. When the weight is uneven, the wheel wobbles as it spins. You feel that wobble as a vibration, almost always at highway speed.
Symptoms that need alignment
- Car pulls to one side on a flat road with hands light on the wheel
- Steering wheel sits crooked when driving straight
- Tires wearing unevenly (more on inside or outside edge)
- After a hard pothole hit or curb impact
- After replacing a tie rod, control arm, or other suspension part
- After a collision repair
Symptoms that need balancing
- Steering wheel vibrates at highway speeds (typically 55 to 70 mph)
- Vibration in the seat or floor (rear tires unbalanced)
- Vibration disappears below 50 mph
- After a wheel weight has fallen off (you can sometimes see the marks)
- After a tire patch repair
Why both after new tires
When you buy new tires, the shop balances them as part of the install. But the alignment is unaffected by tire change, if your car was misaligned with the old tires, it is still misaligned with the new ones, and the new tires will start wearing unevenly within a few thousand miles. Spending an extra $100 to $140 on an alignment after new tires often pays for itself in tire life alone.
DFW pothole season
After every Texas freeze-thaw cycle and every heavy rainstorm, the metro's roads gain a new generation of potholes. Hitting one hard enough to bend a control arm or knock the alignment is a real possibility on Belt Line, on 75, on Coit, on the Bush Tollway. If your steering does not feel quite right after a hard hit, get the alignment checked.
What the numbers actually look like
- Tire balance, all four wheels: $50 to $80
- Wheel alignment, four-wheel: $100 to $140
- Both together with new tires: $150 to $220
- Tire-life savings from a proper alignment: roughly 25 percent of tire life
