You can't set camber or toe in your driveway without the right equipment, but you can spot the signs of a bad alignment early and rule out the cheaper causes first. These six checks take about 20 minutes and can save you from paying for an alignment you don't need, or from wearing out a new set of tires because you waited too long.
Key takeaways
- A car that pulls or has an off-center steering wheel on a straight, flat road is the classic sign of misalignment.
- Check tire pressure first: one low tire causes the same pull as bad alignment.
- Feathered or inside-edge wear points to toe and camber problems.
- Get a professional alignment after new tires, suspension work or a hard pothole hit.
What Wheel Alignment Actually Means
Alignment is the set of angles that decide how your tires meet the road. Shops adjust three main ones:
- Toe: whether the fronts of the tires point slightly in or out when viewed from above. Wrong toe is the biggest cause of fast, feathered tire wear.
- Camber: the inward or outward tilt of the tire viewed from the front. Too much shows up as wear on one shoulder.
- Caster: the angle of the steering axis viewed from the side. It affects straight-line stability and how the wheel returns to center.
These angles drift over time from worn bushings, pothole impacts and curb strikes. Fixing them needs a proper alignment machine, but the symptoms are easy to read yourself.
6 DIY Alignment Checks
- Set the tire pressures first. Check all four tires cold and inflate to the pressure on the driver's door jamb sticker, not the maximum on the sidewall. A tire that's 5–6 psi low will make the car pull toward that side.
- Do the straight-road test. On a flat, empty, straight road (not a crowned one that slopes to the side), hold the wheel lightly at 30–40 mph. If the car steadily drifts to one side, or the steering wheel is off-center when you're going straight, alignment is a likely cause.
- Read the tread wear. Run your palm across the tread in both directions. A sawtooth or feathered feel means toe is off. Wear concentrated on the inner or outer shoulder points to camber. Use a tread depth gauge on the inner, center and outer grooves to compare.
- Try the tape measure toe check. With the car parked straight, measure between the tire centerlines at the front of the front tires and again at the rear, at the same height. A large difference compared with your spec is a sign toe is off. It's rough, but useful for spotting a big problem after a curb hit.
- Look and listen for loose parts. Raise the front safely on jack stands, then grab each tire at 9 and 3 o'clock and rock it. Play here suggests worn tie rod ends. Rocking at 12 and 6 o'clock points to ball joints or wheel bearings. Worn parts must be replaced before an alignment will hold.
- Note when it started. A pull that appeared right after a pothole, a new set of tires or suspension work is very likely alignment. One that changed when the weather got cold may simply be tire pressure.
When to Get a Professional Alignment
Book an alignment if any of these apply:
- You've just bought new tires (protect the investment from day one).
- You've replaced steering or suspension parts such as tie rods, control arms or struts.
- You've hit a deep pothole or curb and the steering now feels different.
- Your checks show a steady pull or uneven wear and tire pressure is correct.
Many manufacturers suggest checking alignment roughly once a year or at every second tire rotation. Ask for the printout showing before-and-after measurements; a good shop will provide it.
Alignment Costs and What to Ask For
Prices vary by region and vehicle, but a front-end (two-wheel) alignment is the cheaper option for cars with a solid rear axle, while most modern cars with independent rear suspension need a four-wheel alignment. Some tire shops sell lifetime alignment packages, which can pay off if you keep the car for years.
Before you pay, ask whether any worn parts were found, and get the measurement printout. An alignment done on worn tie rods or bushings won't last.
Tools for Your Own Alignment Checks

Frequently Asked Questions
How do I know if my car needs an alignment?
The most common signs are the car pulling to one side on a straight, flat road, a steering wheel that's off-center when driving straight, and uneven or feathered tire wear. Check tire pressure first, because a low tire causes similar symptoms.
Can I do a wheel alignment myself?
You can check for alignment problems and make rough toe measurements at home, but setting camber, caster and toe accurately requires an alignment machine. For a lasting result, have it done professionally.
How often should I get an alignment?
Follow your owner's manual. As a general guide, have it checked about once a year, when you install new tires, after suspension or steering repairs, and after any hard impact with a pothole or curb.
Does a bad alignment damage tires?
Yes. Incorrect toe in particular can scrub tread off quickly, and wrong camber wears one shoulder of the tire. Fixing alignment early protects your tires and can improve fuel economy.
Is it alignment or balancing?
Alignment problems cause pulling and uneven wear. Balancing problems cause vibration, usually felt in the steering wheel or seat at highway speeds.
The Bottom Line
Rule out tire pressure and worn parts first, then use the straight-road test and tread wear to decide whether you need an alignment. If the signs are there, a professional alignment is cheap insurance for your tires. Learn more about reading wear patterns in our guide to tire cupping and keep wear even with regular tire rotation.
