So what kind of tires to get?

[TAKPAK]

Hi Lisa. We have almost the same 5'er as you do, except ours is a 3810 (RV fridge), and it's a 2017 year model. We have the Sailuns on ours, which are the 14 ply ones, same as yours. Ours are the original tires, which means probably next year we'll be looking for replacements (the 5 year age out plan). That said, I've been watching them, and no signs of any abnormal wear or deterioration. Been happy with them. Also have a TPMS (Pressure Pro) too. When we change, I'll probably sell them to my farmer neighbor, as he's always happy to get a good set of used tires for the farm implements he has. I'll be checking out Sailuns again, as well as possibly Maxxis and maybe a couple of other brands that are well known. I may go with an "85" aspect ratio instead of the "80" since the extra 1/2 inch of height will not be a problem for us.

Good luck tire hunting!
