What to Check After Hitting a Deep Pothole
That deep pothole hit has a very specific sound. It is part thud, part crunch, part “please tell me that was not expensive.”
The good news is that your car does not need you to panic. It needs you to do a smart little roadside check, listen for changes, and know which signs mean “keep an eye on it” versus “pull over and call for help.”
First Move: Get Out of Traffic and Let the Drama Settle
After a hard pothole hit, resist the urge to diagnose everything while still rolling through traffic. If the car is still controllable, slow down smoothly, avoid sudden steering, and find a safe, flat place to stop.
AAA warns that a blown tire or broken suspension part can make a vehicle harder to control, and sudden swerving or harsh braking around potholes can also create risk. That is why the first check is not mechanical; it is safety. Get yourself out of the danger zone before playing driveway detective.
Check the Tire Sidewall Like It Owes You Money
The sidewall is the part of the tire you can see from the side, and it takes pothole hits personally. Look for bulges, bubbles, cuts, cracks, scrapes, or any spot that looks swollen compared with the rest of the tire.
NHTSA advises drivers to inspect tires for sidewall damage such as cuts, punctures, bulges, scrapes, cracks, or bumps, especially before longer trips. A sidewall bulge can point to internal tire damage, and that is not something to “watch for a few weeks” like a suspicious houseplant.
Look at the Rim, Not Just the Rubber
A tire may look fine while the wheel rim quietly took the hit. Check the outer edge of the wheel for dents, bends, cracks, fresh scrapes, or a spot where the tire bead no longer looks evenly seated against the rim.
This matters because a bent wheel may leak air slowly, shake at speed, or make balancing difficult. AAA notes that hard pothole impacts can damage a tire or wheel, dislodge wheel weights, affect steering, and even bend or break suspension parts.
Watch the Steering Wheel on the Next Slow Roll
Once the tire is not visibly flat and the car seems safe to move, pay attention at low speed. Does the steering wheel sit crooked while driving straight, pull left or right, or feel oddly loose?
A pothole impact can knock the wheels out of alignment and affect steering, according to AAA. Alignment issues may not look dramatic from outside the car, but they can make the vehicle harder to control and cause uneven tire wear over time.
Listen for New Noises From the Corners
A healthy car has its usual soundtrack. After a deep pothole, listen for new clunks, knocks, squeaks, grinding, or a rhythmic thump that changes with speed.
Consumer Reports notes that potholes can damage, bend, or loosen steering and suspension parts. That means a new clunk near one wheel is not just your car “being dramatic”; it may be a control arm, tie rod, strut, shock, ball joint, or related part asking for a professional inspection.
Feel for Vibration Before Blaming the Road
A new vibration through the seat, steering wheel, or floor can be a strong clue. It may suggest a bent wheel, tire damage, wheel imbalance, alignment issue, or suspension problem.
Consumer Reports says excessive vibration may be a sign of a misaligned, unbalanced, or bent wheel, internal tire damage, or suspension trouble. My road-buddy rule is simple: if the vibration was not there before the pothole and now it is, do not let the road take the blame automatically.
Do the Slow-Leak Test Over the Next 24 Hours
Not every pothole injury reveals itself right away. A tire can lose air slowly if the rim is bent, the bead seal is disturbed, or the tire has hidden damage.
Check the tire pressure when the tires are cool, compare it with the pressure listed on the driver-side door placard, then check again the next day. Consumer Reports notes that keeping tires at the recommended pressure helps reduce pothole damage risk, while under- or overinflation can affect a tire or wheel’s resistance to impact.
Peek Under the Car for Leaks and Hanging Pieces
A deep pothole can hit more than the wheel. If the car bottomed out, look underneath from a safe angle for dripping fluid, a loose plastic splash shield, dangling trim, or anything that looks lower than usual.
Do not crawl under a car on the roadside, and do not touch hot exhaust parts. Just do a quick visual sweep from the side, then get professional help if you see fresh fluid, scraping panels, or metal parts that look bent or out of place.
Check the Dashboard, but Don’t Let It Be the Only Judge
Warning lights can help, especially tire pressure monitoring alerts after a hard hit. Still, the absence of a warning light does not guarantee everything is fine.
A bent rim, damaged suspension part, or sidewall bubble may not immediately trigger a dashboard alert. Treat the dashboard as one voice in the conversation, not the entire committee.
Pay Attention to the “Delayed Symptoms”
Pothole damage can show up later, which is why a calm follow-up check matters. The car may feel acceptable at 30 km/h but start vibrating at highway speed, or a tire may look fine at the curb but lose pressure overnight.
For the next few drives, watch for pulling, shaking, steering-wheel wobble, uneven tire pressure, new noises, or the car feeling like it floats, bounces, or wanders. AAA has reported that 1 in 10 drivers in a survey sustained pothole damage significant enough to require repair, so this is not rare-driver paranoia; it is sensible vehicle care.
Know When to Stop Driving
Some pothole hits move straight into “do not keep going” territory. Pull over safely and arrange help if the tire is flat, the sidewall has a bulge, the steering feels unstable, the car pulls hard, fluid is leaking, or the wheel looks bent enough to affect the tire seal.
A vehicle that feels hard to steer, bounces strangely, or makes loud clunking sounds after impact should be inspected before you push your luck. The repair bill for a tow is usually easier to accept than the repair bill for a damaged tire, wheel, suspension, and whatever else got invited to the problem.
What to Tell the Repair Shop
You do not need to walk in speaking fluent mechanic. Bring useful details: which wheel hit the pothole, the speed range, what you felt through the steering wheel, and what changed afterward.
A good shop may inspect the tire, wheel, alignment, suspension, steering components, and underside. If the hit was serious, ask them to check for wheel runout, hidden tire damage, bent suspension links, and loose wheel weights, not just “top up the air and send me off into the sunset.”
Document It Before You Forget
If the pothole was on a public road, take photos only if it is safe. Capture the pothole, nearby landmarks, your tire or wheel damage, dashboard alerts, and repair receipts.
Some cities, insurers, or road authorities may require specific documentation for claims, and policies vary by location. Consumer Reports notes that pothole-related insurance coverage can depend on the policy and type of damage, so it is smart to keep evidence before the details blur into “that terrible road near the thing.”
Pit Stop!
- Keep a tire-pressure gauge in the glove box; it tells the truth before a slow leak gets sneaky.
- Photograph the wheel and tire right after the hit if you can do it safely.
- Check pressure again the next morning, because pothole damage loves a delayed entrance.
- New vibration after a pothole is not “just road feel”; get it checked before longer drives.
- Ask the shop to inspect the wheel, tire, suspension, and alignment as one connected system.
Don’t Let One Pothole Steal the Whole Trip
A deep pothole hit can be annoying, loud, and occasionally expensive, but a smart check can keep it from becoming a bigger roadside saga. Look at the tire, rim, steering, noises, vibration, pressure, and underside before assuming everything is fine.
Your car usually gives clues after a hard impact. Read them early, document what changed, and get a proper inspection when something feels off. That little bit of attention may save your tire, your suspension, and your next adventure from a very avoidable plot twist.
