Tire size on FDDS

[Gaardelli71]

I want to get tire covers but don't know the size as we haven't picked up our new camper yet. Can someone tell me the size so I can get great fitting covers. Also looking for black covers...where to buy?

I have them on my 38FDDS but I can't remember the size of the tire/wheel off the top of my head. I can check this weekend. I believe the tires are 15"? The covers are sold by total diameter size.

It seems that all makes of covers are sized different, like 24-26". I guess I'm looking for the diameter of the tire from side to side.
Thanks,
Dena
