I run kenda 27" exacutioner's. I like how they perform all around, but love them in the mud. Just wish they'd make them in 28's. But i've had since i got the my Brute and show very little wear. Thats fire roads, trails, mud, and some actual road time on them. I have yet to get a locust tree thorn to be able to puncture them...and we have alot of them around here. But no matter what, if you get any good mud tire...it's going to wabble or shake at high speeds. I've had mine up to 65 mph. It shook, but never felt unstable. I think one of our sponsor's (Mud -Throwers) has a tire called Innova "Mud Gear" and they look to be a good happy medium type of tire or the Kenda Bounty Hunters. Everybody rides different or rides in different places and likes different stuff, so it's going to come down with what you're looking for and what you want to get out of the tire. Hopefully with everyones input you'll be able to get something you like.
