I've just purchased a new Gulfstream Super C motorhome built on the Chevy Kodiak chassis. I paid for the Alcoa aluminum wheels option thinking each aluminum wheels is approx. 30# lighter than steel. By my calculation 6 X 30# meant and extra 180 # of carrying capacity. Now I'm distrubed to realize it's really only 4 aluminum wheels plus two steel wheels. It seems the inside rear wheels on the dualie are steel. Did I get ripped off or is this the way it is on all rigs appearing to have aluminum wheels?

Yep, the manufacturers use steel wheels for the inside position on the duels. I suppose you could pay for two more, but they are not normally included in the option. JMHO

Moderator will no doubt jump in on this, but if I recall from earler threads, the vehicle's rear wheel studs will not accommodate pairs of Alcoas. Basically, wheels too thick. That was at least on the Ford E450s many of us have. But riddle me this - Neighbor has a late model 39' Winnebago diesel pusher on Freightliner chassis. I looked through the outside rear outer Alcoas and guess what? White steel wheels.
So maybe there's a way to mount six, but four seems much more common.

Yep, you only get four. I just sold a mid level DP and it had 4 Alcoas. I've looked at a lot of mid--high end DPs over the years and I can not recall seing aluminum wheels used on the inside dual position on any of them. The spare, if one, will be steel, also.

I purchased the Alcoas as an option on my F350 dually pickup a few years ago and I was pretty surprised that it was only 4 alloys with the inside duals being steel also.

A friend of mine had a tow truck with Alcoas on it also, his had 4 alloys and 2 steels also.

So it would appear to me that it's common practice.

I couldn't say if additional alloys would fit on the insides, but from everything I have read the alloy wheel option is purely cosmetic, so it would make sense that they only include the wheels that show.

It is common place to have steel wheels on the insides. I worked for a Tractor/Trailer Tire Fleet Service and most of our clients had steel on the inside w/Alcoa's on the outsides. You can however pickup a used set of aluminum budds and have them but on the inside. You will have to have the studs replaced. Its not really a big job. I've probably done it several dozen times if not hundreds of times.
YMMV

Regarding the Alcoa wheels being only "cosmetic". I was also interested in these 1) For the weight reduction, but also very interested in 2) The trueness of the rim I understand to be more true cold and espeicially as they heat up. This results in better tire wear and along with the reduced weight, decreases rolling resistance, thus a small mileage increase.

Can anyone else confirm the second point, ie: better trueness of the rim?

Thanks,

Karl

My opinion regarding weight and trueness is that they are probably both true benefits of alloy wheels. I personally wouldn't want them on a heavy truck because I hit a curb in my F350 and one of the front wheels (Alocoa) shattered like glass and caused a bunch of damage, had the wheel been steel it probably would have just blown the tire and bent the rim.

I guess there are benefits either way, but I wouldn't think that the weight & trueness issues would make enough of a difference to really justify the cost.

With all of that said, I've put aftermarket alloy wheels on all of our regular cars, and they were all purchased for cosmetic reasons alone. Although I suppose I could justify some of the cost because I use the OEM wheels to run snow tires during the winter.

Well I have first hand experience with Alcoa wheels on my class C... I installed a set of Hot Shot Alcoa`s just for "looks" and was amazed with the ride improvement[emoticon] I took the wife out for a drive and did not say a thing just to make sure it was not just me...she turned to me a said what else did you do?...were the ride was improved was on the sharp edged bumps/expansion joints the bang,bang was just about gone..using the same tires and both steel wheels and Alcoa`s were balanced and phased matched by myself using a RFV balancer. Also yes my inside duals are still the steel wheels.
