Learn English – “Don’t you…” question

grammaticalityquestions

I'm studying English for 10 months. I suppose myself to know it quite well now. But I'm confused about one thing. I noticed that some of my English speaking friends sometimes ask

"Don't you tired/hungry/etc?"

Is this normal/grammatically correct to make such questions? Because I've googled by phrases and found quite a lot of examples of using such questions?

Here are some examples:

"Don't you tired?" is grammatically incorrect in Standard English, but may be part of the local dialect.

Auxiliary forms such as do, does, did are used with a main verb to frame a question. For example: "Do you speak German?", "Don't you speak German?", where the infinitive speak is present.

But they have no grammatical function in a sentence such as in the one you quoted, because there's no main verb. For example, in the sentence "Don't you tired?", tired is not a verb, but an adjective. Such a sentence is unacceptable in Standard English.

Since it's natural for us to google for answers, it's recommended that you do it by typing, as in this case, say, "How to form questions in English". You might end up on an authentic site that you could learn from.)
