The 589's are a rough tire, IMHO. My nephew and I bought Grizzlies at the same time and he put on 589's and I put on Lites. When I ride his it is heavier steering and much harsher ride. Also have found that the 589's will have more problem with sliding sideways on offcamber areas. They are a good tire and will really pull and dig but I am not a fan of them.
My mudlites are smooth once you get up and going. But at slow speeds they are alittle choppy.
Pat- I think I know what your talking about I think its just the way the tires ride on the ground. They are awfully rounded tire and I think on hard pack the contact patch is just a small section inthe middle and they can seem to wounder a bit. I know I have a harder time keeping my Grizzly striaght with the big tires on then I do with the stocks on!
I agree with Starky...I run between 4.25 and 4.75 pounds. When I started out I was running 5 & 5.5 pounds and noticed that the center 1/3 of the tire was seeing all the wear. They perform much better with lower air pressure.
