Why does my car pull to one side?

Concerns & risks

You were trying to drive straight, but the moment you relax your grip the car drifts toward the shoulder.

Pulling can wear tires and make driving tiring.

Causes & evidence

Common causes include uneven tire pressure, alignment issues or worn parts. NHTSA notes alignment keeps the car from veering on a straight road. See tire pressure and tread.

What to do

1. Check that all tires match the recommended pressure.
2. Look for uneven tread wear.
3. Get an alignment check.

Common mistakes: Common mistakes: assuming alignment is the only answer and paying for it before checking pressure. A low tire on one side can cause a pull. Road crown, the slight slope roads have for drainage, can also cause a mild drift. If the steering wheel is off-center or tires show feathered wear, alignment is likely. After hitting a big pothole or curb, have alignment checked. Also check brakes, since a sticking caliper can pull and may smell hot.

Speed Man tip: Hitting a big pothole can knock alignment off.

Wrap-up: Check pressure. Then alignment. Watch tire wear.
