I think you meant "large 32s" on the RR. LT285/70R-17 are a 32.7" diameter and 11.2" width. As for me, I plan to swap to LT285/75R-17 when the K03s come out in that size (this summer) which will get to the "large 33s" (33.8" diameter while maintaining the 11.2" width) along with RPG adjustable perch collars in the front to level her out. Stock tires look a bit too small for me.
In August BFgoodrich is going to come out with 315/70/17 KO3 and I plan on getting those until I got 37" tires but I there another thread where a guy was able to throw on 37" tires just by replacing the springs and 25MM spacer kit.
