Its not that they're "that bad"... Its just that they don't have the grip that more dedicated tires have. At 25psi I had difficulties over rocks. At 23psi is it was a lot better, but still shy of the performance of Hi's KO's.
I'm not a rich man with wads of disposable income
but I do plan on replacing or suplimenting my tires before I go to Paragon again.
(By suplimenting I mean getting a set of take-off rims and putting the hard core tires on them and switching wheel/tire sets whenever going wheeling.)
