you have to break the bead first, after that 2 long screw drivers or long pry bars will work and dish soap for the bead. Pretty easy just try. good luck
i used the tire machine at work, a little difficult trying to clamp the rim, due to it being only 11". Seating the bead was also alot of fun. If you have the cash, have someone else do it.
I just drive over the edge of the quad tire right up close to the rim with my truck, then spin the qaud tire 180 and drive over it again, make sure both tires are dry or it will just slide off. It helps to have 2 people and turn the truck tire around the curve of the quad rim as you drive over it, sometimes the second person needs to stand on the quad tire to keep it from standing up depending on the size of tire. Also may have to do both sides, then I use the back ends of 2 crescent wrenches to work the tire off. Put the new ones on, then add some dish soap to the bead bounce the tire a couple times to allign the bead and hit it with air. Also do it on hard grass ground not the drive way you'll scratch up the rim and if the ground is to soft it can be a pain.
Sure enough it is silverbacks that I'm trying to mount. One of my friends has a tire machine at their shop. He'll do it for me in the next couple days I hope. Thanks guys.
