1997? Fleetwood prowler tire and brake size

Hi all,

My parents are gifting me a 1997? (im guessing from the stickers present near the door frame) Fleetwood prowler 26H. Problems I face are: the trailer is several hours away from both me and parents, with no plans to go get it until next month (as of April 27, 2024). Parents and I have no idea what the condition of the tires and brakes are. I want to be prepared and have 4 new tires and brakes ready to go to replace when I go get it over memorial weekend so I can tow it back with less worries. Local (up to 3 hrs away) RV places and online resources have been no help. 
Thanks in advance.
