Hi Fellow GMCer's
MY first post to this group. I have a question about rims. A local guy scrapped a 1 Ton dually and has 4 of these fancy 16" aluminun rims to sell that were on the dually. He let me borrow one and it seems to fit the GMC ok. Problem is the center hole in the rim is slightly larger than the gmc steel rim and does not locate on the GMC hub. The aluminun rims come with steel sleeves that slide over the studs into oversize stud holes on the rim. Seems this method will have all the weight on the studs? Don't know if this was the case when mounted on the dually or not. Is this a common setup and will it work for the GMC.? I would still need to purchase a couple 16"steel rims for the front and put on some hub caps. Is there a aftermarket steel rim available that fits? THANKS

There are some steel rims in the 16" size, but they quite hard to find (at least in the Midwestern United States). Alloy options are available (look at the Applied GMC website), but not cheap. The original 16.5" wheels are still a viable option, though the availability of tires in that size is constantly shrinking.
The issue of hub-centered vs. lug-nut fastened wheels comes up quite often, and I think that everyone is happiest with the hub-centered option. However, many seem to be running the others with not a lot of reported problems. If you use the search function on the GMCnet, you should be able to find a fair amount of information on wheels that will help you in your search.

I think the important part is that when the rim is mounted and the lug nuts tightened, that the rim is concentric(I think that is the word) I look a BIG trucks that have little tabs on the hub to center the wheel and I'm sure it's not those tabs keeping things in place when rolling down the road. Someone(Rick D maybe) made a point that it is the wheel being clamped against the hub buy the torque on the fasteners that keeps everything in place.
However, it certainly is a pain to get a non hub centered wheel to rotate round if there is any clearance between the studs and the wheel, but if you get it right on install, it stays right.

They make them already. They are called hub adapters. They are crap. (At least the plastic ones are).

Someone could make a spacer ring to fit between the hub and the larger holed rim.

I used a different solution on my 78 Royale. I replaced the 16.5" steel
wheels with 16" steel wheels from Chev & Gmc 1 Ton FRONT wheels. Up to 1999
or 2000 (before metric) They are hub centered, but with the front brake
calipers that I run on my coach, there was an interference problem. How I
solved this was to machine some aluminum wheel spacers that were the same
thickness as the extended part of the front hub. I pressed out the original
wheel studs and replaced them with 1/2" longer studs. I then machined a
piece of stainless steel equal in thickness to the wheel with the Outside
diameter about .002" smaller than the wheel Inside diameter. these stainless
pieces are attatched to the hub with Flathead screws with allen sockets. I
now have hub centered 16" steel wheels again. I had a very difficult time
getting the wheels to run true without the hub extensions. She runs 75 mph
now with no wheel shake. With sand blasting, powder coating, long studs,
spacers etc., I still am into it for less money than the Alcoas. But this
won't be everyone's cup of tea but it works for me. Jim Hupy

I was cruising the LMC Truck Parts website, and saw they have 16"x6" and 16"x8" wheels listed for a GMC 3500 truck. No specs are shown, so I have no idea of their weight carrying capacity. Can these be used for the front of the GMC Motorhome to help with the rut running as they would serve to increase the front track.

I am certainly not an expert on wheels, hub centered or lug-centered. Until Jim had the Eagle wheels produced in hub-centered version it seemed the lug-centered wheels were "just" fine. Check some of the old posts for reference. No doubt the hub centered wheels are superior but the wheels you are referring to may be fine if the price is right.
It is sometimes helpful if we know your location in trying to provide direction (you may be "next door" to a fellow GMC'r who can give you direct help).

Ernie,
IMO hub centered rims is always preferable to lug centered.
The correct, and OEM design, is for the hub center to carry the load and the bolts or nuts to hold the rim on the mounting flange.
The lug centered came about when the custom after market rim where made to fit any and all hubs. Some had special offset washers for the different bolt circle patterns.
A spacer ring can be made with an inside step to solve the center size difference. The rim would need a step/bevel machined on the inside to match, unless there's one already. The step/bevel would lock the ring from ever working out. The ring would have a press fit on the rim.
As a machinist I have repaired and scrapped many hubs/axles because of rims that look nice, but lugged centered.
Have seen vehicles on the side of the road with a wheel off, due to broken studs.
A stud will develop hair line cracks along the thread root, and it may not be visible until it breaks off.
Hope this helped.

The Eagle wheels that Jim K sells are ALL hub centered. The difference between the two types are the size of the center hole. The older GMC wheels that we use were .031" smaller hole. The new wheels are .031" larger center hole.
I bought some of the newer size Eagle wheels with the .031 larger hole and designed a spacer for the extra .031" diameter. I bought a roll or .015" shim stock by 1/2 inch wide from McMaster Carr. I put it all the way around in all 6 wheels.
Guess what happened? The wheels centered just fine without the spacers and with in 5 miles ALL of the spacers I installed fell out. I have checked the space several times over many thouands of miles and a .015" gauge always slips in to the gaps just fine.
You do not need any spacer and the larger hole wheels work just fine. I have never heard of anyone having a problem using these .031" larger hub centered wheels.
A year or so after I bought my Eagles Jim K. got Eagle to make a run of these same wheels with the .031" smaller centers. This is what you guys are now calling hub centered. They cost extra and buy you absolutely nothing.
I suggest you go with the standard hub centered wheels rather than the special smaller ones.

Keep in mind all aluminum Eagle wheels use a lug with a tight fitting sleeve that fits INTO the wheel. (This is for both Lug centered and Jim K's hub centered.) This type of lug centered wheel has been reported to work "just fine" and I believe it.
Most lug centered wheels use cone shaped nuts to center the wheel. There have been reports that this works "OK." But seeing how many lugs I have had break on me, I wouldn't trust them.
Hub centered (and most steel dually wheels) have lug holes larger than the lug and flat lug nuts. (Normally the nuts have captive washers.) The depend on the pilot hole to center the wheel. There isn't any GOOD way to use wheels with larger pilot holes on our coaches. (Without jumping through hoops.)

Ernie,
What's the manufacture date on those six 16.5" tires he had in stock?
Every day since that date is one day wasted of the 5 years maximum you
should use them, IMHO.
In other words, if they were manufactured a year ago, you're paying
for 4 years of usability, not 5.

About a year ago I stopped by an in dependant tire shop in northtern
Mississippi. I talked to the owner about 16.5" tires. He had 5 in stock
and would order the sixth one. When he went online, he searched for a
couple of minutes and said he finally found one. I asked the date code on
the ones in stock and found out they were 3 years old. He recommended going
with 16" tires based on finding replacements while traveling.
I called Jim K. and decided on the Eagle non-hub centered wheels and found
new E rated tires at Tire Easy.com.

Seriously consider NOT using the 16.5's OR VERY seriously check the manufacture date of those "in stock" tires.
