Please correct and comment.

1.All kind of tiger is dangerous.
2. All kinds of tigers are dangerous.

Your use of ‘all’ indicates there is more than one. This means that you cannot use the singular form.

Here’s an example of how the singular and plural forms can be used.
The tiger is (a) dangerous (animal).
Tigers are dangerous (animals).

I think this can be acceptable: Any kind of tigers is dangerous. (Edited)

Also, you may use ‘any’ and ‘all’ in both singular and plural forms. It depends on the related noun being count or noncount. For example: All that glitters is not gold.

“Any kind of tiger is dangerous.”
woud be acceptable but NOT
“any kind of tigers…”

Yes, yes, it’s ‘tiger’.

Having just looked at the second part of your statement a little closer, I think that your comment about countable and uncountable nouns with ‘all’ needs further clarification too as it depends on a lot more than that. I’m sure you wouldn’t say that “All type of information is useful.” would be correct as ‘information’ is uncountable.

You will agree that ‘type’ is not the related noun in the original question. However, you could say: ‘All the information is useful’ (‘information’ is the intended/related noun) or ‘All types of information are useful’ (‘types’ is the implied noun) or ‘Any type of information is useful’ (no problem here).
