I think that your premise is sound and why I run the 255/85/16's instead of anything larger. The weight and change the overall diameter doesn't cause a great deal of loading of the drive train as compared to a 34" or 35" tire.
I have a couple friends who run SS LTB's in 34" and they both said that if they were to do it again, they would have stayed with the 33" tires. They can feel the difference in how the overall diameter impacts the gearing, thus the loading of the drive train.
However, with all that said, I'm presently waiting for the 4.56 Nitro gears from JTS. The MAIN reason I'm doing with these gears is to eliminate the "questionable" early build rear ring and pinion gears (at least, that is what I told my lovely spouse), secondary is the added help the lower gear ratio will give me when attempting challenging obstacles. Since mine isn't a daily driver, I can "afford" to make this change.
So, IMHO, the cumulative effect of increased weight of larger tires (which I think is greater than your reference numbers, at least in my case with SS tires) and the mechanical change in effective gear ratio with a larger diameter tire. My experience says that 33's are about as large as I would want to go before considering re-gearing the drive train...

I was referencing bfg KM's. Thanks for the response.
