My son rides a 450 Kodiak, with a set of Mudlite XLs( in the stock size) on it.It has more than enough power to turn them, and it works great in the mud.That being said, I decided to go with Swamplites(again stock size) on my 550 Grizzly, because I think that the Mudlites are pretty hard on the drive line, they do hook pretty hard, and I know from years of drag racing that some tire slip can save drive line parts a lot of abuse. My Swamplites have gotten me through every where that I have gone with them , and they are 6 ply construction, giving much better stiffness, for less side roll and sway. I'll tell you right now, that these tires have made my atv a whole new animal, and before someone says replacing worn out tires will make a big difference on any machine, I replaced mine with just 100 kms(60 miles ) on them.
