"Wise of you" and "wise for you" are two ways of saying the same thing.

Sometimes!

As usual, English has a nasty way of biting back.

'Wise of' or 'wise for' can both be used when talking about future tense and pretty much mean the same thing, but not so true when we use the past tense.

'It looks like rain. It would be wise for/of you to take an umbrella.' Both make sense

'Oh, it's starting to rain. It was wise of you to bring an umbrella.' Here we cannot use 'for'.

So I guess the safest way is just to use 'of' in every case.
