Alcoas on a 4106

LarryN 4106 · June 15, 2009, 05:52:46 AM

Can someone give me model numbers for the Alcoa wheels that would work for a 4106? Are these "hub piloted" or "stud piloted"?

I am emailing back and forth with Alcoa but they are asking these questions.

thanks

Larry, they are stud pilot. The use of "Budd" style rims might help. Good luck!

A "standard" wheel in the truck industry is 8.25 wide x 22.5 (or 24.5) dia. This would accomodate a 11R tire or similar. Not sure about a 12R, but it would not take much checking to figure it out. The wheel mfg. should be able to tell you the wheel width based on the tire you want to run. You just have to know the mounting (hub pilot or ball/stud aka. Budd style). Oh, and whether or not you want them polished (inside, outside) or machine finish. If buying Alcoas, check into their "Durabright" finish...stays lookin' really nice for a long time.
What size tires are you planning on running?

Larry, you will also have to replace your wheel studs to a longer stud for the alcoa wheels on the 06.>>>Dan (BTDT)

Alcoa part numbers for ball/stud mount (Budd) style wheels (not hub pilot), in 8.25"x22.5"

Polish for steer 883111

Polish for drive (outer) 883112

Machine finish (drive inside) 883110

Yes, I forgot about that. I have already gone thru this with my GMC Motorhome, and had to replace the studs on that as well.

Thanks to everyone for all the help.

If you want to look good from the outside, use steel wheels on the inside dual and longer inner nuts with aluminum on the outside.

If you are looking for used wheels, I believe hub piloted wheels might be more available. I was looking at the various measurements on the Alcoa web site, and I think a good machine shop could modify hub pilot to stud pilot, though not the other way around.
No comment on the legality, but it's a very small amount of metal that needs to be removed.

Len, are you refering to the large hole in the center of the wheel that it "pilots" or centers itself on? What about the chamfer around each hole? And the diameter of the lug hole on a hub pilot wheel is larger than that of a stud pilot wheel.

I don't think it is a good idea. A "wheel off" incident is usually not good thing.

Used wheels are usually $125-$150 each, regardless of mounting style.

Need used wheels? I got some.

I though that when I looked (some time ago) the hub pilot wheel had slightly smaller stud holes, so modifying would mean turn the center hole a little larger, redrilling the stud holes and champhering each hole. I may be mistaken about the stud hole size and don't know the cost of machining.

I take it all back, maybe not a good idea.
