What it does

Wheel alignment is adjusting the angles of your wheels so all four point exactly the way the manufacturer intended relative to the road and to each other — think of it like squaring up a picture frame that's gone slightly crooked. There are three angles a shop adjusts: toe (whether the front edges of the tires point slightly in or out, like a person walking pigeon-toed or duck-footed), camber (whether the wheel leans in or out at the top when you look at the car head-on), and caster (the forward-or-backward tilt of the steering axis, which affects how strongly the steering wheel returns to center after a turn). When any of these is off — usually from hitting a pothole or curb, or just from suspension parts wearing over time — the car can pull to one side, the steering wheel can sit crooked even when driving straight, and the tires wear unevenly because they're scrubbing sideways slightly with every rotation instead of rolling straight.

Frequently asked questions

How often do I need a wheel alignment?

There's no fixed mileage interval the way there is for an oil change — alignment doesn't drift out of spec on its own under normal driving. Instead, get it checked after specific events: hitting a significant pothole or curb, any suspension or steering part replacement (tie rods, control arms, struts), or buying new tires. Many shops also recommend a check once a year as cheap insurance against tire wear.

Do I need an alignment every time I get new tires?

Not strictly required, but strongly recommended — especially if your old tires showed any uneven wear pattern, which is itself a sign the alignment was off. Getting an alignment with new tires protects that investment; skipping it risks scrubbing the new tread unevenly just like the old set.

What's the difference between camber, caster, and toe?

Toe is whether the tires point slightly inward or outward when viewed from above (most common cause of edge tire wear and pulling). Camber is whether the wheel tilts in or out at the top when viewed from the front (also causes edge wear, plus affects cornering grip). Caster is the forward/backward tilt of the steering pivot axis, which mostly affects steering wheel return-to-center feel and high-speed stability rather than tire wear directly.

Is a DIY alignment actually accurate?

A string or toe-plate DIY setup can get toe reasonably close for an enthusiast willing to spend an hour measuring carefully, but it can't properly measure camber or caster, and it's far less precise than a shop's laser alignment rack. Treat DIY alignment as a rough fix to stop immediate tire scrubbing, not a substitute for a proper shop alignment.

Is a lifetime alignment package worth it?

Chains like Firestone sell lifetime alignment packages (roughly $200 for as many alignments as you need for as long as you own the car) as an add-on when you get an alignment done. If you drive on rough roads, hit potholes often, or plan to keep the car many years, it can pay for itself after just two extra visits. If you rarely need re-alignment, a single $89-150 visit is cheaper.
