one thing to remember about fitting larger wheels/tires.

for every fraction you add to the hieght,also needs to be added to the width.
the evo trucks are topsy turvy as its, any addition to the hieght of the COG is negative without adding to the width of the stance.

or to put it this way:
if you raise the COG then you need to widen the stance to keep the truck from rolling.
