Not sure why they even give you a rear wheel measurement when the factory rods are not adjustable
Take a look at the Maxxis Liberty or the Maxxis Rampage. The Rampage comes stock on the new Pro R's.Approximately 25 hours on the machine if I recall. I still run the Stock tires till they wear out and then will shoot for a more square tire. Problem is getting a tire that is good for snow and mud and still does well in hard pack. Alaska has all the above terrain.
But, it’s a DRY COLD they said!!!!
