Cash flow has been tight, and I still have a legal amount of tread on the
tires on my 07 2500Hd 4x4 so I have not yet replaced the tires. Currently I
am running a 265 75 16 on stock alloy wheels. I would like to go to a 285
75 16, but I have been told they should not be put on my current rims, and
that for the new rims I need a 5" backset.

There are not many 16 inch rims available with a 5" backset.

As a result one local tire shop said I should go with 17 or 18 inch.

Now let me ask a couple questions.

Why do I need a 5" backset?

Does it have to be exactly 5"?

I am not a chrome whore, and actually do not like the idea of having a huge
chrome blob on the end of each axle. A simply alloy wheel with a simple
design like the one on my stock wheels is more than adequate. (its what I
like even) With that limitation its even harder to find rims. In 16 or 17
with a 5" backset. I have found a lot with 4.5, and a few with 4.84, and
even a few with more, but not many with a backset close to 5". I have been
looking at an 8 inch rim for this application.

So again, why and how precise?

I remember reading 4.5" backspace as a minimum.

Search e-bay or local sources for Hummer H2 rims. They're 17X8 with
the correct bolt pattern. I have 285/70R17 on my 2006 2500hd 4x4 with
those rims. I needed to trim just a little of the front bumper's
plastic and use wire ties to pull the front inner wheel well liners
back a little, but no rubbing, no lift.
