I have not heard of anyone doing it yet. I have looked at it too, but not talked to anyone about it. There is not a lot of clearance in the wheel well. I took a few measurements and it looks just slightly too tight. The big issue I have with the 13” tires is I cannot locate a LT to fit. So if I/we are on vacation it could be difficult to find a replacement. I thought I found a 13” LT on tirerack.com, a long time ago and a week later while trying to find it I could not. Personally if I could go with an LT that was the same size I would probably go that way. But again it could be difficult to locate one in a pinch.
