Since the TT is new to us, I haven't had it loaded to full GVWR yet, so I don't know how much more "squat" there will be when fully loaded, but at present there is plenty of room for a bigger tire/wheel combo.
Here's info from Discount Tire's website on the Michelin LTX I'm considering for the TT. These I have on the TV and they have good recommendations:

I'm still looking to see what load range this tire is. It is said in the ad to be "load index 108, or 2205 lbs".
I believe other TT owners are running this tire. Not positive it is exactly the same tire, but I think so. Still trying to learn..
