Many dealers sell new trucks with lift kits and big tires --- of course they charge twice what you could get them for aftermarket.....so I don't see how they could claim any warranty problems if you did this yourself.
It would have to be a pretty bad dealer to claim that bigger tires caused a transmission problem.
Really, big tires would be much less of a load on the trans than when you tow near the max the truck is rated for, right?
MPG? Don't even think about complaining about your mpg after doing a modification like this......expect a 20 to 30% increase in your gas use..........OUCH! With gas heading to $4.00+ a gallon, I expect we'll see fewer big tire, raised trucks.
In changing times, one must live by unchanging principles.
