Biggest Tires for Stock Suburban K2500?

Team (if I may call us that);

I have a question as to maximum tire size I can go given the following:

Current info:
* Vehicle: 2002 Suburban K2500 (3/4 ton 4x4)
* Keeping Stock Suspension
* Stock Tire Size on this truck was 245/70-16
* Wheels have been Upgraded to 17 x 8"
* Current Tires on truck are 255/75-17 and have no issues with rubbing (but, they look a bit close to the front fenders).

Criteria:
* Want a failry aggressive pattern (Say a BF goodrich AT type?)
* Want Wider, but do not want tires to Rub (forward, reverse, turns, etc.)
* Want a decent weight Rating (e.g. 3,000#'s per tire?).


Given the above; what is the maximum tire size I can fit? I was thinking a 275/70-17 tire since I can't find a good tire in a 285-60/17.

Suggestions appreciated.

Thank you,

285'S will fit but you will rub, 265's fit real nice and give the burb a good look.
