Thor Axis Wheel Cover Size

[MGoBlue]

I was wondering if anyone remembers the size for the appropriate wheel cover for the tires and wheels on a Thor Axis. Mine is at storage and I thought I might get a quicker answer here than if I run over there and measure. (I swear I am not usually this lazy!) I am trying to take advantage of an online sale.
