Installing a runflat is a little more difficult, but very doable. My set up is a Harbor Freight, with some mods and I use it with a no scuff tire tool (similar to a mojo). The first bead will go on pretty easily, then comes the second bead. Use good technique, patience and you will be able to get it on. When putting on that second bead, some guys use a ratcheting tie down opposite the side where you start to hold the bead down towards the center of the tire. Also, if it's not really warm or hot where you are doing the install, a heat gun to warm up the tire, especially the last 12 to 18 inches really helps. Tires need to stretch to get over the rim and a warm tire stretches better than a cold one!!
I use a No Mar and like it very much. The warranty on the plastic parts helps. I somehow got into mounting tires an have mounted over 50 run flat tires for my self and others so it does work and much better that the Harbor Freight so don't waste your money. Get the best No Mar you can get and enjoy it. Also get the 3 of the extra hand clamps and a yellow thing. They will tell you they will not work on a car tire but they do and they replace the wood blocks. The yellow thing hold the tire and keeps it from walking around on you.
No Mar has the paste they recommend, I have never tried it because I use Dyna Beads and it would hold them. I also do not use tire lube for the same reason. I use Silicone, not WD 40 just Silicone. It works very well as a lube and is absorbed by the rubber so it does not affect the Beads. This is just what I do others may have another way.
