In my opinion there is no better Mog tire than the XM-47. I ran them on my 416. While the chevron tractor tread may LOOK like it doesn't run well on pavement, it's actually the straightest, smoothest rolling Mog tire I've experienced. They are very well made, balance perfectly, wear well, and overall are a very high quality option.
In western states this is undoubtedly less of a concern, but anywhere mud or organic soil is encountered, you'll quickly be reminded that most 4X4s clear their tires with wheel speed and the associated centrifugal force. Unless you're driving a Hellgeth U10,000 Dresden Breslau champion rig, wheel speed is not an option in a Mog. Therefore the tread pattern of the XM is necessary to shed mud.
I will concede that on slick rock having a larger contact patch would most likely be preferable.
Overall however, I think the XM-47 is the ultimate Mog tire. They ain't cheap though!
