Take a guess at the size on these tires/wheels?

Anybody want to take a guess at the size of the tires and wheels on the truck in above link? Even better, what do you think the backspacing/offset is on those wheels?

I have a 1986 K10 that I will be restoring for my wife one of these days, and I'm trying to decide on which wheel / tire size I will be using.  The ridiculously big mud tires and dumb trailer wheels on it now have to go. Ran across this picture in the above link and really like the look and stance of that truck.

Definitely looks sharp...I'd hazard a guess at a 10" wide wheel, no idea on the b/s though.

Those tires look too fat for the wheels in that pic.

I've seen the image within the article, and while I might not be knowledgeable about the size and wheel type, the patterns on the tires make it seem like mud tires. I couldn't zoom in since it's an old photo, so take that with a grain of salt.

Once had some tires that looked close to those in the picture. They were 32" 12.50s on a 15" wheel.

I just looked at that picture again. I'd guess 35" highway treads on 10" wide wheels with an add a leaf/block lift.

I'm going to guess 33x12.50s on 15x10 wheels and no lift or roughly 2 inches of kift

Basing that on an old picture of my 79 K10 I used to own. It had the same size tires on 15x8 wheels. The top of the wheel is as high as the bottom edge of the door and the wheel to fender lip gap is about the same

Thanks for all the replies. It will be a while before I get to this truck project, but I think I have settled on 33x12.5 on 15" rim's. The ones in the above link look like road tires to me. I'm leaning toward road tires or all terrain.
