22.25-22.50 ( depending ) is the magical number
right in there they will all have some contact
Also depends on the JBA arms, some have a bit more girth through the area that hits.
I'd almost bet that one is over 23
Sorry for being late, I'm back with the measurements.
From the middle of the wheel to the bottom of the fender is 23''.
The tire size is 31x10.50R15
