Will these wheels work on My truck?

[M5-]

I have a 65 SB Stepper that has been lowered about 4" in the rear and 3 1/2" in the front. My buddy has a set of 6 bolt wheels that are 17 x 9's with a 4 1/2" backset that he wants to sell me but they don't have tires on them so we can't even try them for size. Will these fit my truck decently with say a 285 55 17 or something close or will the tires rub? My running gear is all stock right now ie rear end and front control arms still drum/drum.

I've searched quite a bit but just can't seem to find the exact answer I'm looking for. Its the 9" width that scares me a bit.

Thx
