Signs of Pothole Damage: Why Your Tire Has a 'Bubble' in the Sidewall
What does a bubble in a tire sidewall mean?
A bubble or bulge in the sidewall indicates the internal tire structure has been damaged. The tire's steel belts or fabric layers have separated from the rubber. This creates a weak spot where air pressure pushes outward. A sidewall bubble is not repairable and requires immediate tire replacement.
How Potholes Cause Sidewall Damage
A pothole strike compresses the tire wall with extreme force. The impact can separate the tire's internal layers. Unlike tread damage, which is localized, sidewall damage affects the structure that contains air pressure. The tire's sidewall is thinner and less reinforced than the tread. Damage here compromises the entire tire's integrity.
Why a Sidewall Bubble is Dangerous
A bubbled sidewall is a blowout waiting to happen. The weak spot will fail under normal driving pressure, especially at highway speeds or when carrying heavy loads. The failure happens suddenly with no warning. You lose tire pressure instantly, potentially losing control of your vehicle. This risk makes sidewall damage an urgent safety issue.
Signs Your Tire Has Pothole Damage
- Visible bulge or bubble on the sidewall
- Sudden vibration or pulling to one side
- Tire pressure warning light activation
- Visible dent or impact mark on the sidewall
- Loss of air pressure over hours or days
Other Pothole Damage Beyond Sidewall Bubbles
Potholes can also cause bent rims, broken suspension components, and alignment issues. Check your entire wheel after hitting a pothole. Look for dents in the rim, cracks in the sidewall, or unusual vibration. Even if you don't see a bubble, have a mechanic inspect the tire and suspension for hidden damage.
What to Do If You Find a Sidewall Bubble
Do not drive on the tire. Stop immediately and call for roadside assistance or drive slowly to the nearest tire shop. Avoid highway speeds. A bubbled sidewall can fail at any moment. Replace the tire before returning to normal driving. Do not attempt to patch or repair a sidewall bubble. Replacement is the only safe option.
Can You Claim Pothole Damage?
Some municipalities cover pothole damage claims. Document the pothole location, take photos of your tire damage, and file a claim with the city. Keep repair receipts. Success varies by location and damage severity. Even if a claim succeeds, it may take months to process. Having proper insurance that covers pothole damage is valuable protection.
Frequently Asked Questions
Is a sidewall bubble always a blowout risk?
Yes. A sidewall bubble indicates structural failure. The tire can fail suddenly. Replace it immediately rather than risk a blowout.
Can I patch a sidewall bubble?
No. Sidewall patches do not provide safe repairs. The damage is structural, not surface-level. Only replacement is safe.
How much does a pothole tire replacement cost?
Tire cost varies by type and size, typically $100 to $300 per tire in 2026. Some shops may charge additional disposal fees.
Should I check my suspension after hitting a pothole?
Yes. Potholes can bend suspension components, damage shocks, or knock your vehicle out of alignment. Have a mechanic inspect the entire front end.
