New Alcoa Wheels for my 2018 Tiffin Wayfarer

So after fighting with replacing the rubber valve stems for steel ones, new valve extenders, jury-rigged extender stabilizers for the wheel simulators, etc. I bit the bullet and decided to upgrade to a 16x5.5 Alcoa Sprinter 3500 Dura-Bright Evo 6 Wheel package.

My first issue was finding the wheels. Most tire shops I talked with wanted to sell me only 4 wheels (most not even specific to the Sprinter) claiming the inside duals had to remain steel as aluminum wheels wouldn't fit as the wheel lugs were too short for the wider wheel profiles. Seems they were not aware that Alcoa had introduced new hub-centered wheels specifically for the Sprinter chassis hubs a couple of years ago that had thinner surfaces which exactly matched the thickness of the steel wheels, allowing aluminum for both the inside and outside duals. Then I ran into them saying that because the wheels are discontinued they cannot be found anywhere.

Bottom line is I found a great set at BuyTruckWheels.com (https://buytruckwheels.com/products/...ight-6-package), said a prayer before pressing submit with my credit card info, and lucked out. Within a week and a half I had received all 6 wheels, hub covers, lug nut covers, and a great valve extender kit for the duals. Came in 4 shipments (2 via FedEx from Las Vegas and 2 via UPS from Ohio). The wheels were all double boxed for extra protection. They also have a great YouTube video online about this specific set for the Sprinter 3500HD chassis if you are curious!

I took them to my local Les Schwab today and for less that $290 they mounted and balanced all the tires, mounted them on the vehicle, installed the hub covers & wheel nut caps, and installed the extenders for the duals.

Looks great and I've dropped weight! I also have the piece of mind knowing I'm not going to lose air out the valve stems or extenders on my next trip...

Best,
-Mark

Look ma, no crazy extensions, strange homemade grommets for the simulators, or overspray!

That looks great! Well done, all to often the wheels make the vehicle.

That looks great. Keep 'em shiny with White Diamond polish.

What is the advantage of having all six chrome as opposed to 4? Just weight?

Weight is one, but for me the primary objective was to go with a much better valve stem extender setup on the longer steel valve stems on the inside duals for better reliability. With the steel rims the rubber valve stems need to go (they are both under rated for the recommended tire pressure and they flex and eventually break off). Even if you get after market steel valve stems installed to replace the rubber ones the steel wheel rim design is so narrow at the stem it is difficult for extenders to be mounted properly. Now I have a setup that is both very simple and quite reliable.

Best,
-Mark

Congrats on the new wheels! They sure do look great! But, I donít understand the comments about lower weight. Itís true that the overall weight of the vehicle has decreased. However, it doesnít help the issue with the low OCCC, does it (since the wheels arenít supported by the axles, frame of suspension)?

Some articles that talk about sprung weight, unsprung weight, rotaional mass and their impact on drive trains, braking, acceleration. ..

https://www.tirebuyer.com/education/...f-wheel-weight

https://www.fitmentindustries.com/bl...-weight-matter

And yes, the feds include the weight of the wheels n the calcs for OCCC for these reasons.

They look real nice. When I bought my 2011 a year ago the wheels were in terrible shape and took me almost a whole day and a container of aircraft aluminum polish recommended by some Airstreamers to bring them back. Since then I have only had to clean them with Windex and paper towels. What I do is after washing my rig, I do all the glass with Windex and paper towels and as they get wet and dirty I finish them up on the wheels.

They all look great. I have 22.5 rims on my rig with 8 bolt hubs. Aluminum wheels are very expensive and very hard to find.

Not hard to find. Yes expensive.

Thanks for the articles! You learn something new everyday! For some reason, I was only thinking about the weight on the suspension. But (obviously) the less weight you need to accelerate (and decelerate) will help with gas mileage and braking distance.
Most of the articles are written about high performance cars and they seem concerned about 0-60mph times! Obviously that's not our concern, but the same principles apply. I certainly never thought about how the lower inertia has an effect on acceleration. Not sure how much it will help overall acceleration, but every little bit counts! Plus you're sporting some great looking wheels!
