A bubble sticking out of a tire’s sidewall deserves attention even when the tire still holds air. Do not plan another trip on a tire with a confirmed outward bulge. Arrange a professional assessment and either a suitable spare installation or transport to a tire shop.
This guide focuses on a visible bulge, rather than an ordinary tread puncture. For a tire that has already lost pressure, see our Los Angeles flat-tire guide.
Why an outward bubble is different from a normal indentation
A bulge projects outward from the rubber. An indentation dips inward. Michelin’s sidewall guidance distinguishes normal construction-related indentations from bulges that indicate structural damage and require immediate replacement. A tire professional should assess an uncertain shape; a phone photo cannot establish that a tire is safe.
Do not press, puncture, or deliberately deflate the bubble to make it disappear. The decision is about the tire’s structure, not whether its surface can be made to look flat. A normal dashboard pressure reading also cannot certify that the sidewall is sound.
What to do when you notice the bulge
If the car is already parked
Leave it parked somewhere safe while arranging help. Avoid moving it to a more convenient driveway or driving to a tire store simply because the distance seems short. Tell the dispatcher whether the tire is inflated, whether another wheel is affected, and whether the car is blocking an entrance.
If you discover the problem during a trip
Focus on reaching a safe stopping place without abrupt maneuvers. Once stopped, assess your surroundings before getting out. Do not stand alongside moving traffic to photograph a wheel. If you are in immediate danger or cannot stop safely, contact emergency services. Our guide to waiting for a tow truck explains how location affects the next steps.
When can a spare solve the immediate transport problem?
A spare installation may be an option when the vehicle has a compatible, usable spare, the correct tools and wheel-lock key are available, and the work area permits a safe change. Tell dispatch about the spare before requesting tire-change assistance. Do not assume a roadside visit includes a replacement tire.
Check the vehicle manual and spare’s instructions for its specific use restrictions. A temporary spare is not an unrestricted substitute for the original tire. If the spare’s condition is unknown, describe that honestly instead of treating it as ready for use.
When towing is the more practical option
Transport may be needed if there is no suitable spare, more than one damaged tire, a damaged wheel, missing hardware, or no safe space to work. The operator must also consider how the vehicle can be loaded. Explain the damage before booking flatbed towing; the presence of a flatbed alone does not determine the entire loading plan.
Call the destination shop before arranging pickup. Confirm that it can receive the car and assess the required tire size. Transport and tire replacement are separate arrangements unless the providers explicitly agree otherwise.
Information to give dispatch
- Your exact pickup entrance and whether the vehicle is on a street, in a garage, or in a private lot.
- Vehicle year, make, model, and any AWD or low-clearance requirements.
- Which tire is affected, whether it holds air, and whether the wheel appears damaged.
- Whether you have a usable spare and wheel-lock key.
- The receiving shop’s address and confirmation that it can accept the vehicle.
For a pickup in Van Nuys or Burbank, provide the actual driveway or parking-lot entrance as well as the street address. A business’s mailing address may lead to the wrong side of a large property.
Common questions
Can sealant repair a sidewall bubble?
No. Treat a confirmed bulge as a replacement issue, not a puncture that sealant will resolve. Arrange tire inspection and a safe way to reach the shop.
Is a small bubble safe at low speed?
Do not use the size of the bubble or a proposed low speed as reassurance. Avoid driving on a confirmed bulge; discuss a spare or towing instead.
Will dispatch bring a new tire?
Do not assume so. Ask what the requested service includes and arrange tire supply with a suitable tire shop.
