I would stick with the oem rims. They're quite good.
Tires, go with an xl rated.
I use reasonably priced foreign tires on all my vehicles now, not the cheapest but something that still meets the oem requirements for weight and speed.
I'm 6'4" but I have a sunroof I just stick my head out of.

The op is looking for ht tires.
We used a koolatron for a few years when transporting medications and food. 110 or 12v allowed us to cool it in the house before going on trips.
Not so much of a need for one now so I just use my big cooler and ice packs.
