Graybear, Thanks for the response! Given I'm already a little tight on width of my trailer, It looks like I won't be able to use my RZR wheels with adaptors. I decided to use the 26" Maxxis tires ( Bighorn's- take offs from my previous RZR) and mount them on new 12" motto wheels that fit the Pioneer. I've found the Bighorns to a great all-around tire. I would continue with the Stock tires, but I've already had a sharp rock puncture one tire (put a plug in it), so now I'm not comfortable getting too far out with the stock with 4 ply tires and no spare. Also, the 26" tire seems to be sweet spot for keeping the geometry of the suspension, steering, clearance, power and CV joints close to OEM design, while allowing just a little more height clearance. That above said, I really love the look of 27" or 28's on the Pioneer.
