The above is spot on about wheel construction, but it is important to note that the Hutchinsons are cast alloy as well.
I went back and forth between the Hutchnson's and just regular old AEV's for my jeep and decided on the AEV's for now. I think that ultimately, you have to sit down and really look at the type of travel you will be doing amd where you will be doing it. The hard part is being truly honest with yourself about what your needs are and shoving the "I am Ferdinand Magellan" thoughts aside. What parts of your travel will necessitate airing down that low? Are you wanting the ability to more easily change a shredded tire on the trail? Have you considered then negative effect that increases in unsprung weight have on acceleration for the times when you aren't on dirt? That and do you just plain want them?
I think a lot of us end up building machines that, while they will definitely get put to use, will never come close to being used to their full potential. I went with the AEV's because I don't anticipate needing to air down that low, carry a spare, and at present, don't have plans to go anywhere that I feel carrying an extra unmounted tire is a necessity, and didn't want to reduce acceleration as I will be adding enough additional weight to the vehicle to begin with. That and most of the time when I see bead locks, it is in rock crawler type vehicles which is a pretty good hint. I need my vehicle to get me home, get me to fuel, get me to food, get me to a campsite, etc. it's a means to an end, namely seeing the world. I tend to avoid the stuff those wheels were designed for as it is often a great place to damage a vehicle.
All that said, if you are planning on getting the AEV bead locks, the Rock Monsters are only $100 a wheel more for what I feel is a superior product.
