Thanks.

I have a spare 16x7 Toyota alloy at home so I'll take it to the office to weigh it for ya.

Steels are easier to perform trail repairs but alloys are definitely lighter which helps on the mpg. Less rotational forces required to get the vehicle moving so I would say alloys are a big plus if you're watching the end results.

thinking of this in a theoretical frame of mind, I don't think alloy vs steel would make any difference in MPG. think of it this way: the energy required to move a 2 ton vehicle is much greater than the energy required to rotate a few pounds of wheel.

Right now I'm running alloys because they came near new tires and were a great deal, when the tires are worn I'll likely switch to steelies. I like the idea of being able to beat out a waffled rim with a BFH if need be.

*edit* found this site -> http://www.wheelweights.net/ <- it seems more geared to car wheels, but a quick look makes it seem like most steelies are about the same as cast alloy (comparing same size). The site lists a 15x7 99 Tacoma 4x4 cast wheel at 21 lbs if that helps at all (only Toyota truck listed)

That sounds about right corax, i've shipped a few and was going to say 23-25lbs for alloys.

For info's sake, my slider set's about 90-100lbs.

Rock sliders? My Stubbs sliders had a UPS label on them that read 44 lbs.

Steelies are around 40 lbs ea. (Eaton 15 x 8)

Seems using alloys saves the equivalent of a bag of gravel - hauling less weight around = less work the vehicle has to do. IMO every little bit helps.

Where the excess unsprung weight is really felt is braking.
