Well, I ended up picking up a set of 5 Pro Comp Xtreme A/T tires in a 35x12.5-17 size from Mario at Adventure Trailers. He had a customer who when to a smaller tire and asked if he could help sell them. He happened to have someone from AT coming out to SoCal so we made a deal and hooked up.
I had them mounted on my H2 wheels this weekend. Sweet. The tires have been getting good reviews so hopefully they will work well.
Not being able to wait for a lift to see how they fit and having read that 35" tires will fit with minor fender trimming without a lift, I decided to throw them on. I am going to need to trim the lower fender lips the tires come up to but that should be it in the front. The rear might be a different story. Because of the box versus a truck bed, there is actually less clearance in width. A lift might have to be done so the rears will fit. I was looking at a 4" lift but really would like to keep it lower. I might start with a 2.5" shackle flip in the rear, since it is sitting lower to begin with and work from there. I would like to keep the CG as low as I can so we'll see how things progress. Glad I was able to test fit things before ordering the lift. Here's some pics.
It would have been nice if there was a choice of a 35x10.5 or 11.5 but the tires companies don't seem interested in those sizes.
