Use the first few minutes after the impact to look for changes
A pothole does not have to leave a dramatic dent to create a problem. The safest first check is to compare how the car feels now with how it felt immediately before the hit.
- 01Reduce speed without making an abrupt lane change
Hold the steering wheel steadily and give yourself room to notice pulling, vibration, or a tire that feels unstable. If the impact was severe, avoid immediately returning to Interstate speed.
- 02Stop in a safe place when traffic conditions allow
Use a parking lot, rest area, wide shoulder, or another location where you can inspect the vehicle without standing close to moving traffic.
- 03Look at the tire sidewall and wheel
Check for a bulge, cut, torn sidewall rubber, exposed cords, a visibly bent rim, or a tire that is quickly losing air. Do not press on a bulging sidewall to test it.
- 04Check pressure if the tire still looks normal
Compare the affected tire with the others and with the vehicle's cold-pressure specification when practical. A pressure warning after the impact deserves more attention than simply resetting the TPMS light.
- 05Pay attention during the next low-speed drive
New steering pull, a crooked steering wheel, rhythmic vibration, rubbing, clunking, or a wheel-speed-related noise can point to tire, wheel, alignment, or suspension damage.
Different symptoms point to different kinds of pothole damage
Impact damage can break internal tire cords even when the tread itself looks fine. A sidewall bulge is not a cosmetic issue and should not be driven on normally.
A changed steering-wheel position or consistent pull can follow an alignment change, but tire damage and suspension movement should be ruled out too.
A wheel can bend at the inner barrel where damage is hard to see from outside. Tire internal damage can also create a new vibration.
Do not assume every post-impact noise is an alignment problem. A hard strike can affect shields, suspension parts, or other components around the wheel and underbody.
Document these details before a tire or alignment appointment
A shop can diagnose the problem more efficiently when you can describe the impact and the symptom instead of asking for an alignment by default.
- Which wheel hit the pothole and at roughly what road speed
- Whether the tire-pressure warning appeared immediately or later
- Current pressure in the affected tire compared with the other tires
- Any new sidewall bulge, cut, wheel dent, or scrape
- Whether vibration happens at low speed, highway speed, braking, or all the time
- Whether the car pulls with your hands lightly centered on a level road
- Whether the steering wheel now sits off-center while traveling straight
- Any new clunk, rub, scrape, or fluid leak after the impact
An alignment check alone can miss the problem
It is common to think of pothole damage as an alignment issue, but alignment angles are only one part of the picture. A tire can be internally damaged while still holding air, and a wheel can be bent on the inside where it is not obvious from the curb side.
If the tire and wheel are sound, an alignment measurement can show whether toe, camber, or other adjustable geometry moved out of specification. If a suspension part is bent or loose, however, simply adjusting alignment may not correct the underlying cause.
For that reason, tell the shop the problem began immediately after an impact. The useful sequence is condition inspection first, measurements second, and adjustment only after damaged parts have been ruled out.
Stop and get help
Do not keep driving on a bulged sidewall or rapidly deflating tire
A tire that develops a sidewall bubble, exposed cords, a deep cut, or rapid pressure loss after an impact can fail without much additional warning. Avoid highway driving and use roadside assistance or a tire professional if the tire cannot safely support the vehicle.
