Changing Tire

efore taking off on our first trip...it did not.  We own a 2017 T@B 320S...any suggestions on the best tool to use to remove the lug nuts and the size of the lug nuts?

You should carry a breaker bar and sockets for removing the nuts and a use a torque wrench to replace them.
If you use a tool that does not provide a torque reading to install the lugs the safe thing would be to stop at a garage to make sure that you have tightened to the recommended torque. Pay attention to the tightening sequence and stop after 100 miles to re-check the torque.

Or Amazon if that's your thing.
If you have locking lugs, think through your plan if the key gets lost or stripped.

Just as others have stated, I carry a 1/2 drive breaker bar. But I carry a full complement of sockets, so the 3/4 just happens to be in the mix. I’m a firm believer that an item should never have a single purpose.

My 320 is 3/4 on the wheels. I got a four size, x/cross bar lug wrench at Harbor Freight for $10.00. As soon as i move my spare to the tongue, it too will have 3/4 inch bolts too. (Bolts on the darn spare are rusted - after two years, and I have been trying for four days to break them loose.) 

Spray the lugs with PB Blaster and allow them to sit overnight before trying to remove them using a breaker bar. You may need to add a piece of pipe to the breaker bar to get more torque. They should come right off.

I went to Harbor freight too and paid 10$. Its got 3 or 4 sizes.
