الإطارات جديدة.

In Modern Standard Arabic, the verb to be is usually not expressed in the present tense.

So:

• الإطارات جديدة = The tires are new
• literally, something like the tires new

This is a very normal Arabic sentence type, called a nominal sentence.

But in other tenses, Arabic does use a verb:

• كانت الإطارات جديدة = The tires were new
• ستكون الإطارات جديدة = The tires will be new

So the missing are is not a mistake; it is standard Arabic grammar.

Because in Modern Standard Arabic, non-human plural nouns are usually treated grammatically as feminine singular when they take adjectives or verbs.

So even though الإطارات is plural, the predicate adjective is:

• جديدة = feminine singular

This is the standard pattern:

• الكتب جديدة = The books are new
• السيارات سريعة = The cars are fast
• الأبواب مفتوحة = The doors are open

So the agreement is based on a rule of Arabic grammar, not on the actual number in English.

It is a general rule in MSA for non-human plurals.

That means many plural things that are not people will take feminine singular agreement:

• البيوت كبيرة = The houses are big
• الهواتف غالية = The phones are expensive
• الأشجار طويلة = The trees are tall

But human plurals usually take true plural agreement:

• الطلاب جدد = The students are new
• الطالبات جديدات = The female students are new

So the sentence الإطارات جديدة follows a very common and important rule.

Because الإطارات is the subject of the sentence, while جديدة is the predicate.

In this kind of sentence:

• the subject is often definite
• the predicate is often indefinite

So:

• الإطارات = the tires
• جديدة = new

This structure helps Arabic show that the sentence means:

• The tires are new

and not:

• the new tires

That difference is very important.

These two look similar, but they mean different things.

1. الإطارات جديدة

   • a complete sentence
   • The tires are new

2. الإطارات الجديدة

   • a noun phrase, not a full sentence by itself
   • the new tires

Why?

Because in Arabic, when an adjective directly modifies a noun, it usually matches it in definiteness too. So:

• الإطارات الجديدة = both words are definite = the new tires

But when the second word is the predicate of a sentence, it is typically indefinite:

• الإطارات جديدة = The tires are new

This is one of the most useful contrasts for learners to notice.

In careful fully vocalized MSA, it would be:

• الإطاراتُ جديدةٌ

A common pronunciation would be roughly:

• al-iṭārātu jadīdatun

But in normal pause pronunciation, the endings are often not fully heard, so you may hear something closer to:

• al-iṭārāt jadīda

A few useful details:

• الإطاراتُ has nominative -u because it is the subject
• جديدةٌ has nominative -un because it is the predicate
• the final ة in جديدة is usually heard as -a in pause

So learners often encounter it in writing without vowels as simply:

• الإطارات جديدة

The singular is:

• إطار = tire / frame (depending on context)

The plural is:

• إطارات

This plural uses the -ات ending, which is very common in Arabic. Even though this ending is often associated with feminine nouns, it can also be used with many non-human nouns, including nouns that are not feminine in meaning.

So:

• singular: إطار
• plural: إطارات

Because it is a non-human plural, it then takes feminine singular agreement in sentences like this:

• الإطارات جديدة

In standard MSA, no—not in normal usage for a non-human plural like الإطارات.

The standard form is:

• الإطارات جديدة

not:

• الإطارات جديدات

Why? Because جديدات is a feminine plural form, and that kind of agreement is mainly used with female human plurals, not with non-human plurals.

So:

• الطالبات جديدات = correct for female students
• الإطارات جديدة = correct for tires

For non-human plurals in MSA, stick with feminine singular agreement.
