I THINK the 1 1/2" are probably available, but when I was eyeballing the thing I went by that old rule, if a little is good, too much is just right.

Actually, the backspacing would be same as stock with a 1" spacer, and I was having some inside rubbing with 255/70/15 on stock rims, so thought the extra inch would be fine.

It is the extra width of the rim that makes the diff.

I did the rear first, and tried the 2" on the front to check clearance ... better with the stock offset, wider rim and a 1" spacer.

Thought about having the spacers shaved, but their design won't allow it ... the seat for the inner (attaching nuts) is too close to the backside, and on the outer the studs are too close to the front surface.

It was very close to clearing, and with a smaller tire (these are 275/60/17) I think it would clear, and if it wasn't lowered it would be ok, and possibly a little shift of the bed/frame relationship would make it work ...

and if pigs had wings ...
