Lowered C20 16" tires sizes

[sholl10]

Hey guys I been a part of the forum for a while just reading here and there as I have a few squarebodies. I've recently have been building an 82 C20 with a 6.2 diesel and an np833. It's a cool setup and I lowered it about 2" in the front and 4 in the rear . My question is what size tires should I run if I keep the stock 16" wheels up front and bought a set of 16x10s off wheel vintiques for the rear? The truck is obviously not fast and I don't need slicks but if I could find a set of nice street tires preferably inexpensive I'd be happy. Thanks in advance for any help. I've searched around and could not find any info on the subject .
