A friend of mine runs the mud lites on his 2wd rancher and loves them. Great traction, but be carefull of the sidewalls, there a little weak. He hasn't had any problems but I know many that have but all have had problems when running low tire pressure. My friend runs about 5~6lbs and no punctures so far. Another guy that rides with us just got some swamplites and they look like basically the same tire except they are a little heavier. I think you would be happy with either.I ride primarily trail and was considering either swamplites or mud lites. i have heard the Mud Lites actually do really well on trails and have a huge weight per tire advantage as opposed to others. What do you guys think?
