I just put a brand new maxxis c6001 to the full test this past weekend riding tons of mud, losse dirt/sand, hard pack, loom, rocks and whatever else you can think of and it came out awesome. Hooked up great in almost all conditions, a little squirly on hard pack but nothing serious. I had a dunlop 739 or something like that on it before this and road the same place and had all sorts of problems with control. The maxxis is a little heavier than other tires but man i dont think i will switch to anything else. It got a little worn but from what i put it through its nothing. Also the 110/90/19 i got seemed to be a little skinnier than my 110/90/19 dunlop but i had no problems at all with it. I reccommend it.
