Why Does My Steering Wheel Shake at Highway Speed?

The short answer
A steering wheel that shakes at freeway speed and settles down as you slow is most often a wheel that's out of balance, which AAA says a balance service usually fixes. Other causes include a bent wheel, a damaged tire, alignment that's off, or worn suspension and steering parts like tie rods. If the shake is new and sudden, slow down and look at the tires, and have it checked before your next long drive.
You get up to speed on the 15, and somewhere past 55 the steering wheel starts to buzz in your hands. Slow down and it goes away. Speed back up and it's there again. That pattern has a short list of usual causes, and most of them are easy to find. Here's what usually causes it, what you can check yourself and when to pull over.
Why does my steering wheel shake only at highway speed?
The most common reason is a wheel that's out of balance. AAA describes it as shaking mainly at highway speeds that eases as you slow down, and says a balance service usually fixes it. AAA's balance guide lists vibration in the steering wheel, seat or floor above 45 mph as a sign.
Every tire and wheel has a little uneven weight in it. When a tire is mounted, a balancing machine spins it and shows where to add small weights so it rolls smoothly. If one of those weights falls off, or the tire wears unevenly, the wheel starts to wobble. At city speeds you may not notice. At freeway speed the wobble is fast enough to come up through the steering.
AAA notes that hitting curbs or rough roads can knock wheel weights loose. A bent rim can cause a shake too. One hard pothole or a curb in a parking lot is enough.
What else makes the steering wheel shake?
If balance isn't the answer, these are the next things we look at:
| What you notice | Likely cause |
|---|---|
| Shake at freeway speed, smooth when slower | Wheel out of balance |
| Shake started after hitting a pothole or curb | Bent wheel, lost wheel weight or tire damage |
| Shake plus a thump that matches wheel speed | Tire with internal damage or a flat spot |
| Shake plus pulling to one side or uneven tire wear | Alignment out of spec, often with worn parts |
| Shake plus clunks over bumps or loose steering | Worn tie rods, ball joints or bushings |
| Shake only when braking | Brakes (rotors or a sticking caliper), not wheels |
More on a few of these:
- Damaged tire. A tire can separate inside, where the belts under the tread come apart. It shows up as a bulge or a lump and a shake that gets worse. NHTSA says to check the tread and sidewalls for cuts, punctures, bulges, scrapes, cracks or bumps.
- Flat-spotted tires. AAA says hard braking, a skid, or sitting parked for a long time can flatten a spot on a tire. AAA says flat spots may wear out with normal driving, but severe ones can mean replacing the tire.
- Alignment. AAA lists steering wheel vibration with pulling, a steering wheel that sits off-center and uneven tire wear as signs of misalignment. Potholes, curbs and rough roads can knock it out.
- Worn steering and suspension parts. AAA lists worn ball joints, tie rods and bushings, which wear over thousands of miles, among the causes of a shaking steering wheel. Worn parts also let the alignment drift, so these often travel together.
If the shake only happens when you press the brake pedal, that's a brake problem. Our post on why brakes squeak covers the other brake noises worth knowing.
Is it safe to drive with a shaking steering wheel?
It depends on how it started. A mild, steady shake that's been there for weeks is usually balance and is fine to drive to a shop at normal speed. It still wears your tires unevenly and puts extra load on suspension parts, so don't leave it for months.
Pull over somewhere safe and look at the tires if:
- The shake started suddenly, especially right after hitting something.
- It keeps getting worse over a few miles.
- You hear a rhythmic thump or feel the car pull.
- You see a bulge, a lump or exposed cords on a tire.
A tire with a bulge can fail. Put the spare on or have the car towed rather than driving on it.
What can I check myself?
You can rule out a few things in the driveway in a few minutes:
- Tire pressure. Check all four with a gauge when the tires are cold and set them to the number on the driver's door sticker, not the number on the tire. NHTSA says to check pressure at least three hours after driving for an accurate reading.
- Tread and sidewalls. Look and run a hand carefully over the tread. Bulges, lumps, cords showing or a patch that's worn much more than the rest all point to the tire.
- Wheel weights. Look at the edge and inside of each wheel. A clean spot where a weight used to be, or a strip of adhesive with no weight on it, is a strong clue.
- Bent rims. Look for a dent or flat spot on the outer lip, especially on the side that met a curb.
- Recent work. If the wheels were off recently for tires, brakes or a rotation, mention it. A shake that starts right after is worth having rechecked.

How often should wheels be balanced?
Balance with any new tire, whether it's one tire or a full set, and any time a vibration shows up. AAA Mountain West Group says manufacturers recommend balancing for maintenance anywhere from every tire rotation to once a year. A tire rotation is a good time to have it checked, since the wheels are already off.
Alignment is a separate job. Balance adds weight to the wheel so it spins smoothly. Alignment adjusts the suspension so the wheels point the right way. AAA Mountain West Group suggests getting an alignment with new tires and whenever you notice pulling, an off-center steering wheel or uneven wear. If you need one, our wheel alignment page explains what's involved.
When to bring it in
Bring it in if the steering wheel shakes at any speed, if it started after hitting a pothole or curb, or if it comes with pulling, clunks or uneven tire wear. Don't wait if a tire has a bulge.
Here's what we'd do, in this order:
- A test drive to feel where the shake starts and stops.
- Tire pressure, tread, sidewalls and age on all four.
- Each wheel on the balancer, checking for lost weights, a bent rim or a tire that doesn't run true.
- Steering and suspension parts: tie rods, ball joints and bushings.
- Alignment, if the tires or the steering point to it.

Common questions
Why does my steering wheel shake at 60 mph but not at 40?
That pattern points to wheel balance first. An out-of-balance wheel wobbles more as it spins faster, so the shake shows up at freeway speed and fades as you slow down. AAA lists vibration above 45 mph as a sign of imbalance. A bent wheel or a tire with internal damage can feel similar, so the wheels and tires get checked during the balance.
Is it safe to drive with a shaking steering wheel?
A mild, steady shake that's been there for weeks is usually a balance problem and is fine to drive to a shop at normal speed. A shake that starts suddenly, keeps getting worse, or comes with a thump, a pull or a bulge on a tire is different: slow down, pull off where it's safe and look at the tires before going on.
Will a wheel alignment fix a shaking steering wheel?
Sometimes, but balance is the more common fix for a shake. Alignment sets the angles of the wheels, and AAA lists vibration along with pulling and an off-center steering wheel as signs it's off. If the car also pulls or the tires are wearing on one edge, it makes sense to check alignment along with balance.
Why did my steering wheel start shaking after new tires?
Usually a wheel weight came off, a tire wasn't balanced well, or a tire or wheel has a defect. AAA Mountain West Group recommends balancing with any new tire. Having the balance rechecked is the first step; if it still shakes, the next check is for a bent wheel or a tire that doesn't run true.
Does the shake mean the front or the rear wheels?
As a rule of thumb, a shake you feel in the steering wheel usually comes from the front wheels, and one you feel more in the seat or floor usually comes from the rear. It's a starting point, not a diagnosis, so we check all four.
