ive had quite a few 4 wheelers and a rzr with a lot of different tires
mudlites, mudlite xls, 589s, mudlite xtrs, swamp lites, outlaws, holeshots and countless stock tires
the 589s and outlaws are both pretty aggressive and rough riding tires, neither hooked up on rock worth a crap
all of the mudlites rode pretty good and aren't that expensive (all of which are great all around tires IMO)
I loved the xtrs on my rzr but theyre kinda pricy, rode good and hooked up in/on everything
the holeshots were on a race quad so theyre out...
idk if my swamp lites had a defect or what but they were brand new and after 2 rides all of the top tread block was gone (out of 3 layers), I bought the quad used with tires already mounted or I woulda raised heck..
out of everything I have had I love my tires now (mud lite xls) not too heavy and an all around great tire
all stock tires are garbage as far as im concerned (unless an aftermarket tire that comes on newer units; for ex: the big horns on rzrs and whatnot)
if money is no factor I would go with one of the newer 8ply tires out there
and im sure it isn't in this case
just my 2c
