I bought a couple of sets of these wheels so I could mount some tires I had laying around. The mounting process was very easy (or as easy as mounting beadlock tires gets).
These are attractive. If you want to make them more attractive, you can get replacement rings from companys like Locked Up RC that are direct fits.
There are much more detailed and stronger options out there, but if you are just getting into using beadlock wheels on your scale crawler, or if you are on a tight budget, this is a good place to start.
