Το λάστιχο κλατάρει, αλλά έχω μπάλωμα και ανταλλακτικό.

Yes — λάστιχο has several meanings depending on context.

In everyday Greek, το λάστιχο can mean:

• tire / tyre
• rubber
• hose
• sometimes an elastic band

In this sentence, because of κλατάρει and the idea of having a patch and a spare, it clearly means tire.

So here:

• Το λάστιχο = the tire

Λάστιχο is a neuter noun, so it takes the neuter article το in the singular.

• το λάστιχο = the tire

This is why the sentence begins with Το and not ο or η.

Also, in Greek, many neuter nouns end in -ο, and λάστιχο is one of them.

Κλατάρει is the 3rd person singular present of κλατάρω.

Here it means:

• is going flat
• has a flat
• is punctured / has punctured, depending on context

So:

• Το λάστιχο κλατάρει = The tire is going flat / The tire has a flat

This verb is fairly colloquial. You may hear it especially in everyday speech about tires, but it can also be used figuratively for things like engines, machines, or even people “giving out.”

Yes, it is a normal present-tense form.

Greek often uses the present in situations where English might say:

• The tire is flat
• The tire’s going flat
• The tire has gone flat

So κλατάρει can describe what is happening now or the current situation, not only an action in progress in a strict English sense.

If you wanted a past event, you could say something like:

• Το λάστιχο κλάταρε = The tire went flat

But in the original sentence, the present works naturally because the speaker is describing the current problem.

The dictionary form is κλατάρω.

Greek verbs are normally listed in the 1st person singular present form, so:

• κλατάρω = I go flat / I give out
• κλατάρει = it goes flat / it gives out

In this sentence the subject is το λάστιχο, which is third person singular, so we get:

• Το λάστιχο κλατάρει

Greek does not always need an explicit equivalent of English a/an in this kind of sentence.

So:

• έχω μπάλωμα και ανταλλακτικό

naturally means:

• I have a patch and a spare / replacement

You could say:

• έχω ένα μπάλωμα και ένα ανταλλακτικό

if you want to make the indefiniteness more explicit, but it is often unnecessary.

This is very common in Greek, especially after verbs like έχω.

Μπάλωμα means patch — especially a repair patch used to fix something torn or punctured.

In this sentence, it most naturally means:

• a tire patch
• a patch kit item
• something used to repair the puncture

It can also be used more generally for a patch or even figuratively for a makeshift fix.

It is also a neuter noun:

• το μπάλωμα

In the sentence, it appears without the article because it is an indefinite object:

• έχω μπάλωμα = I have a patch

Literally, ανταλλακτικό means replacement part or spare part.

So in this sentence it means something like:

• a spare
• a replacement
• a spare part

However, if you specifically mean spare tire, Greek speakers very often say:

• ρεζέρβα = spare tire

So:

• έχω ρεζέρβα is more idiomatic for I have a spare tire

The original sentence is understandable, but ανταλλακτικό by itself is broader and less specifically “spare tire” than ρεζέρβα.

In this sentence:

• Το λάστιχο is the subject, so it is in the nominative
• μπάλωμα and ανταλλακτικό are the objects of έχω, so they are in the accusative

So grammatically:

• το λάστιχο = nominative singular neuter
• μπάλωμα = accusative singular neuter
• ανταλλακτικό = accusative singular neuter

But for many neuter singular nouns, the nominative and accusative have the same form, which is why they look unchanged.

That is very normal in Greek.

Because Greek usually drops subject pronouns when they are not needed.

The verb form itself tells you the subject:

• έχω = I have

So Greek does not need to say I explicitly.

If you wanted emphasis, you could say:

• εγώ έχω μπάλωμα και ανταλλακτικό

But normally Greek prefers just:

• έχω μπάλωμα και ανταλλακτικό

This is one of the biggest differences from English.

The given word order is natural:

• Το λάστιχο κλατάρει, αλλά έχω μπάλωμα και ανταλλακτικό.

But Greek word order is fairly flexible, especially for emphasis.

For example, you could also hear:

• Το λάστιχο κλατάρει, αλλά έχω ανταλλακτικό και μπάλωμα.
• Αλλά έχω μπάλωμα και ανταλλακτικό.

Changing the order may slightly shift emphasis, but the basic meaning stays the same.

The original version sounds straightforward and conversational.

Yes, in this sentence αλλά means but.

It links two contrasting ideas:

• Το λάστιχο κλατάρει = the tire is flat / going flat
• αλλά έχω μπάλωμα και ανταλλακτικό = but I have a patch and a spare

So the contrast is:

• there is a problem,
• but the speaker has what is needed to deal with it.

This is a very common and basic conjunction in Greek.
