Help preparing for first long distance RVing vacation

I know it's on your list of obvious things, but how about a new set of dependable tires? We are making the trek to Florida in June. I've never pulled the TT that far, and one of the first things I'll invest in is a new set of tires. I still have some research to do on them, but new skins are top on the list. I've read too many horror stories on here of the tires that are put on these rigs from the factory.
