Anthony Calhoun here, ASE Master Tech with 25 years under the hood. If you just smacked a pothole and your heart dropped into your stomach, take a breath. I've seen everything from zero damage to completely destroyed suspension from a single pothole hit. The difference between a close call and a costly repair often comes down to what you do in the next ten minutes.
Let me walk you through exactly what to check, what to worry about, and what you can safely ignore.

Immediate Inspection Checklist
As soon as it's safe to do so, pull over and run through this list. It takes five minutes and can save you from turning a fixable problem into a dangerous one.
1. Walk around and look at all four tires. Check for an obvious flat, a sidewall bulge, or visible cuts. Pay extra attention to the tire that hit the pothole, but check them all — the impact can transfer force through the suspension.
2. Inspect the wheels. Crouch down and look at the rim edge, especially the inner lip where you can't normally see it. Look for bends, dents, or cracks. Alloy wheels crack; steel wheels bend.
3. Check your TPMS light. If your tire pressure monitoring system light came on, at least one tire is losing air. This could be from a cracked rim, a damaged tire, or just the impact temporarily unseating the tire bead from the rim.
4. Drive slowly and listen. Pull back onto the road at low speed. Listen for clunking over bumps (suspension damage), grinding or humming (wheel bearing or brake contact), or rhythmic thumping (flat spot on tire or bent wheel).
5. Check the steering wheel. Is it centered when driving straight? Does the car pull to one side? Either symptom means your alignment shifted and you need it checked.
6. Feel for vibrations. New vibrations in the steering wheel, seat, or floorboard indicate a bent wheel, tire damage, or suspension component failure.
If everything checks out — no visible damage, no new noises, no pulling, no vibrations — you're probably fine. But I still recommend getting an alignment check within a week. Some alignment shifts are subtle enough that you won't feel them in the steering but they'll chew up your tires over the next few thousand miles.
Tire Damage: What to Look For
Tires are the first point of contact, and they take the worst of it. Here's what I look for when a customer comes in after a pothole hit.
Sidewall Bulge or Bubble
This is the sneaky one. The tire might hold air perfectly and look fine at a glance, but there's a small bulge on the sidewall. That bulge means the internal structural cords — the plies that give the tire its shape and strength — have broken. The only thing holding the air in at that spot is the rubber layer.
This is a blowout waiting to happen. It cannot be repaired. The tire must be replaced. Do not drive at highway speeds on a tire with a sidewall bulge.
Flat Tire or Slow Leak
The impact can pinch the tire between the pothole edge and the wheel rim, cutting the rubber. It can also unseat the tire bead from the rim, especially on low-profile tires. Sometimes the tire goes flat immediately. Other times it's a slow leak that takes hours or days to become obvious.
If your tire is flat, you know the drill — spare tire, donut, or roadside assistance. If you need a refresher on tire changes, I've written a complete guide on APEX Tech Nation that walks you through it step by step.
Tread Damage
Chunks of tread can be torn off by a sharp pothole edge. If the damage is small and doesn't expose the belts underneath, the tire may be okay. If you can see metal or fabric cords through the damaged area, the tire needs to be replaced.
Wheel Damage: Bent Rims and Cracks
Modern wheels take a beating from potholes, especially the large-diameter, low-profile wheel and tire packages that come on so many vehicles these days. There's less tire sidewall to absorb the impact, so the wheel takes the hit directly.
Bent Rim
Steel wheels bend. Alloy wheels can bend too, but they're more likely to crack. A bent rim causes vibration at speed, can cause a slow air leak where the tire bead doesn't seal properly, and creates uneven tire wear. Sometimes you can see the bend by looking at the rim edge. Other times it takes a wheel balancer or straightening machine to detect it.
Mildly bent steel wheels can sometimes be straightened. Alloy wheels can also be straightened by specialists, though not all shops offer this service. Cost for wheel straightening runs $75-$150 per wheel. If the bend is severe or the wheel is cracked, replacement is the only option.
Cracked Wheel
Alloy wheels can crack from pothole impacts. Cracks may be visible on the face of the wheel or hidden on the inside. A cracked wheel is dangerous — it can fail suddenly at speed. Any crack means replacement, no exceptions. Don't let anyone tell you a welded wheel is safe for road use.
Replacement costs: Steel wheel replacement runs $50-$200. Alloy OEM wheel replacement ranges from $200-$800 depending on the vehicle. Aftermarket alloy wheels can be more affordable at $100-$400 each.
Alignment Shift
This is the single most common result of hitting a pothole, and the most commonly ignored. The impact knocks your alignment out of spec — specifically the toe, camber, and caster angles that determine how your tires contact the road.
Signs Your Alignment Shifted
Steering wheel off-center: You're driving straight but the steering wheel is rotated slightly left or right. This means the toe angle changed on one or both front wheels.
Car pulls to one side: The car drifts left or right on a flat, straight road without you turning the wheel. This is a camber or caster shift.
Uneven tire wear: You won't see this immediately, but within 2,000-3,000 miles of driving on bad alignment, one edge of the tire will wear significantly faster than the other. This can destroy a new set of tires in a few months.
Get It Checked
An alignment check costs $50-$100 at most shops, and many will do it free if you're getting the alignment corrected. A four-wheel alignment adjustment typically runs $80-$150. It's one of the cheapest forms of insurance for your tires — a $100 alignment protects $800 worth of tires.
Suspension and Steering Damage
Big hits can damage the components that connect your wheels to the car. These repairs are more expensive but less common than tire and alignment issues.
Strut and Shock Damage
Struts and shocks dampen the impact of road irregularities. A pothole hit can bend the strut shaft, crack the strut mount, or blow out the internal seals causing fluid to leak. Symptoms include excessive bouncing over bumps, clunking noises, and the car sitting lower on one corner. Strut replacement runs $400-$900 per pair (always replace in pairs — left and right on the same axle).
Ball Joint Damage
Ball joints are the pivot points between the control arms and the steering knuckle. A severe pothole impact can crack the ball joint housing or accelerate wear on an already tired joint. A failed ball joint is extremely dangerous — the wheel can fold under the car. If you hear clunking from the front end after a pothole hit, get the ball joints inspected. Replacement runs $200-$500 per joint including labor.
Tie Rod Damage
Tie rods connect the steering rack to the steering knuckles. They're designed to handle steering forces, not vertical impacts, so a bad pothole can bend them. A bent tie rod throws off your alignment and can cause wandering steering. Tie rod replacement costs $150-$400 per side plus an alignment.
Control Arm Damage
Control arms are the structural link between the frame and the wheel assembly. They're tough, but a hard enough hit can bend them, especially the thinner stamped steel arms on economy cars. A bent control arm cannot be properly aligned and must be replaced. Budget $300-$700 per control arm including labor and the required alignment.
Delayed Symptoms to Watch For
Some pothole damage doesn't show up immediately. Over the next few days and weeks, watch for:
Vibration that develops gradually: A slightly bent wheel or tire with internal damage may not vibrate right away but gets worse as the damage progresses.
TPMS light coming on days later: A slow leak from a cracked rim or slightly unseated bead may take days to drop pressure enough to trigger the light.
New noises over bumps: Suspension components weakened by the impact may not fail immediately but start making noise as they deteriorate.
Tire wear pattern changes: Check your tire edges after 1,000-2,000 miles. If one edge is wearing faster, your alignment shifted.
Steering feels different: If the steering feels looser, less precise, or the car wanders slightly, something in the steering or suspension was affected.
When to File an Insurance Claim
Pothole damage is typically covered under your collision coverage, though some policies categorize it as comprehensive. Here's my practical advice on when it's worth filing.
File a claim when: The total damage significantly exceeds your deductible. If you have a $500 deductible and the damage is $2,000 — a bent wheel, damaged tire, and strut replacement — it makes sense to file.
Don't file when: The damage is close to or below your deductible. A $300 alignment and tire repair on a $500 deductible policy isn't worth the claim. Filing can increase your premiums, and many insurers track claim frequency.
Document everything: If you think you might file a claim, take photos of the pothole immediately. Note the location, date, time, and road conditions. Get a police report if the damage is significant. Keep all repair receipts. This documentation also helps if you decide to file a claim against the municipality.
Filing Against the City or Municipality
Many cities and counties have a process for filing damage claims for pothole damage. Success depends on proving the government knew about the pothole (or should have known) and failed to repair it. Gather your photos, receipts, and any records showing the pothole was reported before your incident. Most municipalities have a claims form on their website. The process is slow but can result in reimbursement.
How to Minimize Pothole Damage
You can't always avoid potholes, but you can reduce the damage when you hit one.
Maintain proper tire pressure. An underinflated tire has less sidewall support and is more vulnerable to pinch damage. An overinflated tire has a harsher ride and transfers more force to the wheel. Keep tires at the pressure listed on your driver's door sticker.
Avoid low-profile tires if possible. Those 20-inch wheels with rubber-band tires look great but offer almost no pothole protection. If you live in an area with bad roads, consider downsizing to a wheel with more sidewall.
Don't brake in the pothole. This seems counterintuitive, but braking shifts weight forward and compresses the front suspension, which means less travel available to absorb the hit. If you can't avoid the pothole, release the brake just before impact so the suspension is fully extended and has maximum travel to absorb the blow.
Slow down on rough roads. Impact force increases with speed. Hitting a pothole at 25 mph is dramatically less damaging than hitting the same pothole at 50 mph. When road conditions are poor, reduce your speed.
Keep your suspension maintained. Worn shocks and struts can't absorb impacts properly, which transfers more force to the tires, wheels, and other components. If your car bounces excessively over bumps, your shocks are worn and pothole damage will be more severe.
