what size tires for 17x8 rim??

[lil_sahara450r]

hey guys,
I'm about to order some new wheels for my truck soon and Im going with a 17x8 TT2. I would like to know what size tires and backspacing would work for my setup. I have a set of 2600 dominator bags, c notched, 2 inch drop blocks, and a set of 5 lug axles in the factory rear end in back and I will have a set of disk brakes from a 73-87, drop spindles, and drop springs in front. this is a SWB truck. and i HAVE used the search function with not much luck at all. any help would be greatly appreciated and pictures would be icing on the cake. Thanks guys!!!!

P.S. the fender lips in back were rolled in from the PO, i will be rolling them back out to put the strength back in the bedsides. the sides loose alot of strength with the lips rolled in and get floppy.
