Scratched the curb.. Does my tire need to be replaced?

It depends on the severity of the scratch.

If the scratch is superficial and has not affected the tire's internal structure, it may not be necessary to replace it. However, if the tire is damaged beyond the surface, it is important to replace it as soon as possible to ensure the safety of your vehicle and its occupants.

Here are some factors to consider when deciding whether or not to replace a scratched tire:

Depth and length of the scratch: If the scratch is deep or long, it may be an indication of damage to the tire's internal structure. It is best to have the tire inspected by a professional to determine if replacement is necessary.

Sidewall damage: If the scratch is located on the sidewall of the tire, it is more likely to compromise the tire's integrity than if it is located on the tread. Sidewall scratches should always be inspected by a professional.

Tire pressure: A scratched tire may cause a slow leak, which can lead to a loss of tire pressure. If you notice that your tire is losing pressure more frequently than usual, it is important to have it inspected to determine if the scratch is the cause.

Vehicle type and usage: If you drive a high-performance vehicle or regularly drive on rough roads, it is more important to replace a scratched tire than if you drive a slower-speed vehicle or primarily use paved roads.

If you are unsure whether or not your scratched tire needs to be replaced, it is always best to consult with a professional mechanic or tire technician.
