I’d have to drive it to be sure. But it sounds about right. Just worried about how re gearing will affect overdrive 

Your rpm will be close to what you have before the tire/gear change. However large tires and HEAVY and eat power.

Just say' n.

How long do the 6 speed transmissions typically last? 

That's like asking, How long should a roll of toilet paper last....... it depends on how you use it.
