Question for the electricians out there.
I am insulating and dry-walling my garage. Before I close up the ceiling I am thinking of running some conduit to make things easier in the near future when I have both a 50 amp circuit to plug the 5t...

Conduit size is based on more than just the "will it fit" factor, the National Electric Code takes into account ampacity and heat, making sure there is enough air space inside the conduit so it doesn't overheat. Many factors need to be considered, hence the chart that bobbo posted. Also why when running in conduit you use individual THHN conductors and NOT sheathed cable, since the sheathing both takes space and holds heat, thus derating the ampacity of the conduit.
Pulling cable in conduit is not the easiest especially with multiple bends. If you are not planning to wire it all up yet, I would stay on the safe side and run all 1 1/2" Sch 80 plastic conduit. That ensures that you have the room to pull the right sized conductors when you need to.
Any reason the transfer switch is 8' from the breaker box? Ideally you want it more like 1' away.
