37x13.50/R18 with AEV clearance kit?

[Gravel Dust]

I have a standard ZR2 2500HD Gas. Getting the AEV 37" tire kit. Has anyone run this with 37x13.50 with stock wheels? 37x12.50s are recommended. Seeing how bad they actually rub, if at all.

I didn't test the AEV kit, but mounted up a set 37x13.5 on a Bison package. No rubbing, but very close to the UCAs and if you air down offroad, I think it would rub. Several people running 12.5s with no problem.

I have a thread showing pictures of my test fit.
