I like the 16" rim combo and will eventually get rid of my 35 12.50 15 BFG MTs in favor of 325 75 16 (35 12.50 equivalent) when I switch to 8 lugs. My last set of 35's lasted 10 years, so at that rate the slightly higher price was moot IMO. My vote is the 16's! FYI, we put a Fabtech 4" lift on my brother's 96 extended cab truck. We got a set of 265 75 16 BFG all-terrains that had been returned after 2 days on some soccer mom's suburban (she didn't like the noise) for $75 as demos with full warranty. The BFGs with some some Eagle 580s in 16x8, centers, lugs, mounting and balancing it was $800 out the door! The 265 75 16 is a nice size tire, actually. Fills the wheel well nicely and is a lot cheaper than the larger tires FWIW. That's what I run on my 70 2500. Shop around and try to get a couple of dealers to battle out the price with you! I did that with my 35 12.5 BFG MTs and got them for $125 each.
