The main tires on a -10 tend to wear unevenly and the tire life can be increased by flipping the tire on the wheel after about 150 hours or so. I learned the hard way last time not to wait too long to flip them so this past weekend I flipped them. While I had the wheels off it was a great time to repack the wheel bearings. I've done it a few times now so I was pleased at how quick this all came together!
The wheel pant brackets tend to get kind of loose and you have to really tighten the bolts up a lot to get it nice and firm. The problem is the home made aluminum spacers that the plans have you create will mushroom out over time from this. Mine havent mushroomed out yet but I need to replace them with something like this spacer that planearound.com sells.
