La llanta está dañada.

Because estar is normally used for a state or condition, and here the sentence describes the wheel/tire as being damaged right now.

• está dañada = it is damaged / it’s in a damaged condition
• es dañada would sound odd here, because ser is not usually used for temporary physical condition

A useful comparison:

• La puerta está abierta = The door is open.
• La puerta es abierta = The door is open-minded / open by nature (or it sounds incomplete/unnatural in many contexts).

So in La llanta está dañada, estar is the natural choice.

Because the adjective must agree in gender and number with the noun it describes.

• llanta is feminine singular
• so the adjective must also be feminine singular: dañada

Compare:

• El neumático está dañado.
• La llanta está dañada.
• Las llantas están dañadas.

This is standard adjective agreement in Spanish.

Spanish often uses the definite article more often than English does.

So La llanta está dañada literally includes the, even when English might simply say:

• The tire is damaged
• or in context, just Your tire is damaged

In Spanish, using la here is completely normal because you are referring to a specific wheel/tire that both speakers can identify.

This is an important regional point: in much of Spain, llanta usually means the rim (the metal wheel rim), not the tire itself.

For tire in Spain, people more often say:

• neumático
• sometimes rueda, depending on context

So in Spain, a more natural sentence for The tire is damaged would often be:

• El neumático está dañado.

If you say La llanta está dañada in Spain, many people may understand the rim is damaged rather than the tire is damaged.

These words can overlap, but in Spain they are often distinguished like this:

• neumático = the tire
• llanta = the rim
• rueda = the wheel as a whole, or sometimes just wheel/tire in everyday speech

So:

• El neumático está pinchado. = The tire is flat/punctured.
• La llanta está doblada. = The rim is bent.
• La rueda está dañada. = The wheel is damaged.
  (This can be more general.)

In Latin America, llanta often means tire, so usage depends a lot on region.

In most of Spain, ll is pronounced like the y in yes (or very close to it), so:

• llanta sounds roughly like YAN-ta

A simple breakdown:

• lla ≈ ya
• n as normal
• ta as normal

Also:

• dañada contains ñ, which sounds like ny in canyon
• so dañada is roughly da-NYA-da

Approximate full pronunciation:

• La llanta está dañada ≈ la YAN-ta es-TA da-NYA-da

Not exactly.

• dañado/a = damaged
• roto/a = broken

So dañada is broader. Something damaged may still work, but it is not in good condition.

Examples:

• La llanta está dañada. = The rim/tire is damaged.
• La rueda está rota. = The wheel is broken.

If the object is completely unusable, roto/a may be stronger. If it has dents, wear, or other harm, dañado/a is often better.

Yes, but it sounds a bit less natural in everyday conversation.

• La llanta está dañada = more direct and common
• La llanta tiene daños = literally The wheel/tire has damage

The second version is possible, especially in technical, insurance, or inspection contexts, but for normal speech, está dañada is usually more natural.

The accent distinguishes it from esta.

• está = is (from estar)
• esta = this (feminine singular)

Examples:

• La llanta está dañada. = The wheel/tire is damaged.
• Esta llanta está dañada. = This wheel/tire is damaged.

So the accent is important because it changes the word and its function.

You change the noun, verb, article, and adjective to match the plural:

• Las llantas están dañadas.

Changes:

• la → las
• llanta → llantas
• está → están
• dañada → dañadas

This is a good example of how several parts of a Spanish sentence agree with one another.

Yes, but there is a nuance.

• dañada = damaged
• averiada = out of order / faulty / broken down

Averiado/a is often used for machines, devices, or systems that are not functioning properly. With a wheel or tire, dañada is usually more straightforward.

For example:

• El coche está averiado. = The car has broken down.
• La llanta está dañada. = The rim/tire is damaged.

So dañada is usually the better choice here.

A common way is:

• La llanta se dañó.

This means it got damaged or became damaged.

Compare:

• La llanta está dañada. = The tire/wheel is damaged.
  (describes the current condition)
• La llanta se dañó. = The tire/wheel got damaged.
  (focuses on the change/event)

In Spain, if you mean tire, you would more likely say:

• El neumático se dañó.
