I just have to align the wheels and the one ton conversion is complete! What an awesome system that is truly a bolt on replacement of the original equipment. I can't wait to take it for a spin!

While finishing the install, I went to Midwest Wheel in Des Moines, IA to borrow a 16" steel wheel to test fit on the coach. I'm happy to report that it fits both the front and back of the coach with no issues. If has the following spec's:

Size 16X6
Bolt circle 8X6.500
Bolt hole dia. .670
Hub Bore 4.567
Backspace 8.150
Offset 5.150

The wheel spacer that comes with the one ton conversion allows the caliper to clear the rim. This is a nice option if you don't have the greenbacks for an aluminum wheel.

Here's a link to some pix of the wheel.

When you get them all mounted up, please post pictures so we can see how they look. Are you planning on new lug nuts? New wheels and nuts should look nice. Pricing on the wheel?

Do they fit on the rear hubs as well with no fitment issues?

I plan to trim the wheels like I had on my 16.5's. http://www.gmcmhphotos.com/photos/air-spring-replacement/p53580-sully-bilt-system-installed.html

Another member mentioned that the original wheel covers would also fit (I have not tried that yet).

These wheels fit the rear with absolutely no clearance issues. I have the one ton system up front, so I do not know if they would fit the original front knuckle/hub/rotor/caliper.

I too would like to know. How much did the rims cost?

EDIT - Add on - Very important. Did the center part, the hub bore, of the rim fit sung onto the fornt rotor and rear drums.

You want the center part of the rim to carry the load and never the studs/lug nuts.

Thanks, Tony

Part # X-45329. I can't recall the Brand name. I pick up the rest of them tomorrow and then I'll have more info. I only picked up one of them to do the test fit. I'm friends with a guy who works at MW wheel. That's also why I don't have the exact price. I got a little discount. I think the retail price is $54/wheel.

I do not mean to be a pain in the you know what. Very Happy

I simply want to be extra sure I would be buying the correct new 16" rims for the GMC in Calif.

I see you stated that these rims fit the "One Ton" new front setup and use a spacer.

Does anyone know 100% sure that this rim is the correct rim to fix on the stock GMC front disc brake setup - without the caliper hitting the rim?

I have heard GMC owners talk about the differnece between the bowl and cone style rims.


Thanks!

These are the "bowl" type, not the "cone" shaped. I still have my old front end and will mock it up to check for fit in the next day or two.

Thank you Dave!

I hate to order the rims from here on the east coast and have them delivered to Calif only to find out when I arrive there; that they will not work . Shocked Laughing

Many thanks again..
Tony

Looking at the rim in the photo. It is the same as the 6 rims that are on my non-modified coach rolling stock. It will fit both front and rear without a problem. If you have upgraded to 80mm front brakes, you may or may not have a casting tab to remove.
I could use 1, to replace my incorrect, but get you home spare.
I dressed up my rims with a pretty paint, designed for rims. Wal-Mart, one can will do 1 1/2 rims. Also, used beauty rings on 4 wheels. I keep looking for a deal on 2 more beauty rings, but n luck so far. Need a center cap to finish the wheels for looks.

I believe these are the wheels a few members on here have tried before. They fit the rear but DO NOT fit the stock front.

I just test fit the rim on a parts coach with original equipment up front. The rim collided with the ears on the caliper where the bolts attach the caliper to the knuckle. I'm no engineer, but I don't think shaving enough off to eliminate the collision is a good idea....

I did go re test it on my driver coach and confirmed again that is spins without collision using the one ton system I bought from Manny. There is approx. 1/8" clearance which the wheel guys at MW tell me is enough even with flexing under load. I hope that's the case. It will be a while before I put rubber on the rims to test under load.

Those interested in these rims should remember to contact Jim Hupy about
the thin spacers he makes to correct such interference.
