I am not sure myself! I still run the stock tires on my 650 H1..but my friend has Titan 589s and he swears by em! Also his cousin has some vampires that are sickening ..so I hear...Im sure youll get plent of info here..
hope this helps somewhat!
Benny, not sure what quad your running? Also what use you need your tires for? Currently I'm running ML XL's b/c my dealer wouldn't allow anything else for warranty purposes, not a bad overall tire. There not a pure mud tire but do fine.. Swamplites are my favorite out of the tires you mentioned, I think they look sick but couldn't get them in Canada.. Other tires worth mentioning are MST's, Executioners (lil heavy) & Bighorns (IMO there ugly lol)..
Exactly, your riding terrain and style will be a determining factor in the tires you are after.
For all around hard pack trail riding, you cant beat the bearclaws for handling and wear. The mudlites are a good tire but are also a softer compound and will wear faster, at slow speeds the XL's have a rougher ride as well.
My brother just sold his 27" mudlites and went to some 25" Maxxis Bighorns. He hasn't had much riding time with them, just plowing snow but did find they worked better in the snow then the mudlites did, being a less aggressive tread they wouldn't dig down and sink like the ML's.
