I have Kenda Klaw XC(6 ply) 22x11x8 on the back and love them!! You can swap the direction depending on soft ground or hard ground and the best part is............................they're pretty good price, right around $55-$60each depending on where you get them, which is awesome for a 6ply tire, IMO. Just my 2 cents, I'm sure you'll get plenty of responses on this one.
