Unless you buy some of the very light steel racing wheels, the improvement in ride quality of an aluminum wheel is very noticeable over steel wheels.
Comes down to how are you going to use the vehicle?
Rock crawling? Steel, no doubt in my mind.
Extreme Overlanding with a heavily loaded vehicle? Again, steel.
Occasional Overlanding with some mixed use or long sections of pavement in the mix? Aluminum, no question.
Daily Driver in addition to what ever other uses? Aluminum, no contest.
These points are extremely valid. BTW, this subject comes up often, so a search of the archives would be in order.
Something to mention is that ride quality in my experience is hand's down in favor of alloy.
I have always been a steel is real guy, mostly because I've bashed steel rim lips straight on the trail and driven home. But my current wheels are American Racing Outlaw II and they have little broken pieces of rim lip. I've had to replace one so far (they are about 5 years old). Personally I think there's some truth to the steel/alloy argument, but it's not black and white. I get a noticeably better ride with alloy and some better alloy wheels are extremely rugged.
ntsqd's lay out is about right and obviously the gray area is where the steel and alloy switch over happens. I think for North American overland touring that the argument for steel wheels falls a bit short, since we have a whole lot of pavement and improved dirt roads. Unless you are using your truck for significant amounts of difficult trail with rocks, then I don't think the stronger points of steel wheels really work out over the easier balance and better ride of alloys. I have 33x10.50 BFG MTs at the moment and on 15x7 Outlaw II they only needed a few stick-on weights on the inside surface of the wheels. I don't have
any rim-mounted weights to get torn off on my wheels. There is no way they could do that with steel wheels.
IOW, if you use the steel is more rugged argument here (absent consistent hard core trail use), you are designing for the 1-in-200 chance that a steel wheel
might be the better choice at the expense of the other 99.5% of the time that an alloy wheel is smoother, accelerates better, increases fuel economy and increases the life of your tires by being better balanced. I'm convinced that for what I do with my truck (which unfortunately is a lot of daily commuting) that alloy wheels make sense.
