I have the kutters all around. Great tires. Ride with a friend who has razors, his leak. Replaced valve stem, valve stem core, dipped them. Can't find the leak, think its not sealing around bead. I have had mine on for about a yr. No leaks yet.
Kenda's are heavier, they cost less, seem to hook up equally good. The razors ride better on hard surfaces and are easier to clean up.
The kutters seem like they're made from a harder compound than the razors. Both are good tires.
I have the Kutters on the rear and the Rzr 2's up front. Sweet setup if you ask me. And awhile back you could get the rear kutters cheap, making it a no brainer to save $80 plus on a set. Now the price is close, atleast at Rockymountain.com
Not so sure they make the Rzr2 for a 11" rim thou? The Razr 22x10x11 looks sweet. So for the current price difference I might of went with the Maxxis Razr.
