Dia memeriksa tiub dalam dan injap tanpa perlu mengepam tayar.

Dia is a third-person singular pronoun meaning he, she, or sometimes it, depending on context. Malay does not normally mark gender in pronouns the way English does, so you have to infer it from the situation.

In this sentence, dia simply means he/she.

Periksa is the base word, meaning check or inspect.

Memeriksa is the active verb form made with the meN- prefix. In standard Malay, this is the normal form when the subject actively does something to an object.

So:

• periksa = the root/base word
• memeriksa = to inspect / checks / is checking

Because the sentence has a subject doing an action to specific things (tiub dalam and injap), memeriksa is the natural choice.

Tiub dalam means inner tube.

It is made up of:

• tiub = tube
• dalam = inside / inner

Together they form a noun phrase meaning the tube inside a tyre. This is a common Malay way of building expressions: the main noun comes first, and the describing word follows it.

So tiub dalam literally feels like tube inner/inside, but in natural English it is inner tube.

In Malay, modifiers often come after the noun, unlike in English.

So:

• tiub dalam = inner tube
• rumah besar = big house
• kereta baru = new car

English usually puts the describing word first, but Malay often puts it after the noun. That is one of the most common word-order differences English speakers notice.

Injap means valve. In this sentence, it refers to the valve of the tyre or inner tube.

It is a normal standard Malay word, especially in mechanical or technical contexts. So if you are talking about bikes, tyres, pumps, or engines, injap is a useful word to know.

This is a very natural Malay structure.

• tanpa = without
• perlu = need / necessary

So tanpa perlu literally means without needing to or without the need to.

It introduces an action that is unnecessary:

• tanpa perlu mengepam tayar = without needing to pump the tyre

This is a common and useful pattern in Malay.

Mengepam comes from the base word pam, meaning pump.

When the meN- prefix is added to some short roots, especially one-syllable words like pam, Malay often uses the form menge-.

So:

• pam = pump
• mengepam = to pump / pumping

This is why it is mengepam, not mempam.

Because tayar is the object of the verb mengepam.

Malay word order here is:

• mengepam tayar = pump the tyre

This is similar to English verb-object order:

• pump the tyre

So the structure is straightforward:

• Dia memeriksa... tanpa perlu mengepam tayar
• He/She checks... without needing to pump the tyre

Malay does not normally use articles like a, an, and the the way English does.

Whether something is definite or indefinite is usually understood from context.

So:

• injap can mean a valve or the valve
• tayar can mean a tyre or the tyre

In translation, English often has to add the or a, but Malay usually does not.

Malay verbs usually do not change form for tense the way English verbs do.

So memeriksa by itself does not specifically mark:

• present: checks / is checking
• past: checked / was checking
• future: will check

The time is usually understood from context, or shown with time words such as:

• semalam = yesterday
• sekarang = now
• esok = tomorrow
• sudah / telah = already / completed
• akan = will

So this sentence could mean different English tenses depending on context, though checks or is checking is often the most natural default.

Yes. Mengepam tayar literally means to pump the tyre, but in natural English that often means inflate the tyre.

So depending on context, good translations include:

• without needing to pump the tyre
• without having to inflate the tyre

Both capture the idea well.

Yes. Dan is the standard Malay word for and.

In this sentence it links two nouns:

• tiub dalam dan injap = the inner tube and valve

It works very much like English and.

Malay often allows the subject to be omitted when it is clear from context.

So you could hear:

• Memeriksa tiub dalam dan injap tanpa perlu mengepam tayar.

This can sound natural in instructions, descriptions, or connected speech if everyone already knows who is doing the action.

But with no context, keeping dia makes the sentence clearer.

They are loanwords that have become part of everyday Malay vocabulary.

• tiub comes from English tube
• tayar comes from English tyre/tire

This is very common in Malay, especially for modern objects, technology, and mechanical terms. Even though they are borrowed, they are fully normal Malay words in usage and spelling.

A rough pronunciation guide for an English speaker would be:

• Dia → DEE-yah
• memeriksa → muh-muh-REEK-sah
• tiub → roughly tee-oob
• dalam → DAH-lahm
• dan → dahn
• injap → EEN-jap
• tanpa → TAHN-pah
• perlu → PER-loo
• mengepam → muh-nguh-PAHM
• tayar → TAH-yar

This is only approximate, but it should get you close enough to be understood.
