Symptoms
- Steering wheel needs constant correction to drive straight
- Car drifts to one side when you let go briefly on a straight road
- Pulling is worse at certain speeds
- One front tire more worn than the other
Likely causes
- CommonUneven tire pressure side to sideA lower-pressure tire creates more rolling resistance, pulling the car toward that side.
- CommonWheel alignment out of specToe or camber misalignment causes a persistent pull.
- PossibleDragging brake caliperA caliper that doesn't release fully creates drag on one side.
- PossibleUneven tire wear or mismatched tiresDifferent tread designs or wear levels side to side can cause pulling.
- PossibleRoad crown or crosswindRoads are often slightly crowned to drain water, which can cause a mild, normal pull.
What to do
- Check and equalize tire pressure across all tires first, since it's the simplest cause.
- Test on a flat, straight road away from a crowned center line, holding the wheel loosely to feel the pull.
- Inspect tires for uneven wear side to side.
- Feel each wheel for excess heat after driving, which can indicate a dragging brake.
- If pressure and brakes check out, have the alignment checked and adjusted at a shop.
- Ask the shop to inspect tire condition and confirm all four are a matching type if pulling continues.
Tools and parts
- Tire pressure gauge

When to call a pro
If pressure and brakes are fine, an alignment shop can measure and correct the exact angles causing the pull.
