Tires for a R Pod 172 camper

Fellow Campers: I am sure that this subject is discussed in depth somewhere on this forum, but am seeking advice on tires. I have a 2010 172 R Pod camper that I bought from the original owner. I have had it now for about 6 months learning all about it and seeing how all of the appliances, etc., work. I have not taken it on a camping trip yet. In looking at the tires, I think the ones that are on it are probably the original tires. I did not ask the po if he had ever changed them, and he did not use the pod that much, so, I think they are probably original. Needless to say, i want to change them before I put it on the road to go camping. What tires would you recommend? What do you have on yours? What to buy and what to stay away from? This camper is small and is a single axle. Trailer weight empty is about
2700 lbs. Any advice will be greatly appreciated
