I have 35x12.5x17 BFG MT's
What offset or backspacing should I use?
Best place to buy?

 

this depends on a couple things.... first off, what are you trying to achieve? do you want wider than stock, and if so by how much. do you have a lift? if you are stock you will be limited.

 

I will be putting a 2.5 AS and just don't want any rubbing.

 

I found a set of expedition rims that are 17x8 44mm offset 6 on 135, will these work for my application?http://cgi.ebay.com/ebaymotors/Parts...3A1|240%3A1318
I am worried about hub bore.

 

Yes you can use those wheels. Hub bore is not an issue. I had expedition take-off rims on my 04 (the one in my sig). I"m not sure about running 35's though. I ran 33's with an auto spring 2" leveling kit and had no issues. Good luck..
