<font color="blue">I've got R4s thinking that's what I should have but now am wondering - it does seem to keep the CG a little lower. </font>
i decided to go with R4s for a number of reasons; no regrets. one of the main reasons (and don't take this as gospel) was that i noticed AGI tires doing lots of damage on my logging trails; because i'm logging 30+ cords/year, that's lots of deep ruts to contend with.
