Default I see. I'm not that concerned about an extra one or two tenths of pick up

Weight of the wheels is apparently being used toward the total GVWR of the vehicle, which is a factor as it is weight, but it doesn't have as much effect on as many things as weight of cargo, etc, because it is not sprung weight--it is only seen by the axle ends and tires.


The wheel weight is also being referred to as unsprung weight, which is how the above is explained, and unsprung weight is any weight not supported by the suspension. Unsprung weight can affect the wheel bounce, shock response, wheel bounce, etc. For big vans I don't see it as much of an issue, though.


The rotational mass alluded to is what uses extra energy to accelerate or decelerate an item in rotation and heavy stuff is harder to speed up and slow down. Again compared to the mass of the van itself, I think a small issue.


Personally, on a big van, I think the most important thing to consider with the weight of the wheels and tires is if they get too heavy for you to readily put the wheels on and off, if you do that yourself. The other stuff would likely not show a difference for 98% of drivers.
First, zero to 60 times on an RV is a ridiculous point.. it's not important... unless you don't have the right sized engine...the Mercedes Benz Sprinter is fine for it's size....

Second... with 325 foot pounds of torque.. and the axle ratio it moves the whole vehicle very nicely.

Third, someone already pointed out that the "heavier vehicles" like my dual wheels 3500 would benefit from the steel wheels....

Fourth... it's NOT important for me and overall weight compared to the price of changing them out.. I would have to change all 7 tires including the spare..NOT happening.

And 5th reason.... I NEVER work on my vehicles... Always call the AAA.... that's why I have a membership..
They know what to do and have the tools for doing it right..
I would no sooner change a tire than jump off a building.

Enough said on this subject for me..

Where did it say that any of my comment was directed at you or your van? The post was to clarify that numerous posters referring to weight have been referring to different types of weight and to clarify the differences. No need to take any offense

No worries.. I'm fine with your comments and what I'm sticking with..
If a "professional" advised me to change my wheels, I would probably listen to that.. until that happens or there's some "compelling reason" to change, I'm fine with the current arrangement.

I really liked your earlier comment when you said,

"The steel wheels do have some advantages like holding lug nut torque better without periodic retorqueing and they definitely absorb rock hits and such better. For a heavy hauling van like an RV, the steel wheels are more practical, I think."

.

I don't think you have a choice.

You get whatever comes with the RV.

Premium RVs will come with all AL wheels.

For other RVs, if it is an option, most people would prefer not to pay the extra money if they don't have to.

I have beautiful aluminum polished rims.... they are very nice...

In the picture you posted - you don't have aluminum polished rims. You have standard Sprinter steel wheels with aluminum trim rings added by Roadtrek. Basically like old fashion hub caps.

They're old fashioned... but, I like them fine.

Wheels are unsprung weight. Unsprung weight influences handling and ride far more then the same weight carried above the springs.

Just out of curiosity, where did I (or anyone else for that matter) ever suggest that you should replace your wheels?

You started this thread with a question. As is common this list, folks attempted to answer it using mostly factual arguments, and by clearing up technical misconceptions (e.g., "weight is weight"). I just don't see where anyone even expressed an opinion about your particular wheels, much less said anything that could be reasonably interpreted as criticizing your (apparently pre-made) decision.

Sorry for the rant, but there seems to be kind of a pattern here.

I was rather wondering the same thing and had to go back to see what gt this thread started.
