Picked up a set. Yesterday I pulled off the stock rim and did some measuring.

Stock rim 4.774"
Hub 4.767

There is only .007" on the diameter (.0035" per side) clearance.

The back rims also fit with the same clearance. You just don't see the raised area on the hub until you remove the rim.

I think it's important to have the holes bored concentric to the original hole to 4.774"






I'm working on an idea to heat up the Hummer caps and form a bulge in them to clear the rear hub. The caps look good on.

 

hoot,

Looks good! What a difference the wheels make!
I like the idea of bulging the rear cap to clear the hub. let me know how it goes. It would only have to move out about 5/8 inch or so. I opened my rear caps up with the 4 3/4" hole saw and like the look too. I have seen a lot of caps on e-bay so if you mess one up it's no big deal. Also, I saw some H2 caps for sale on e-bay that had no HUMMER lettering on them. At first I thought it might look bad with Hummer written on the caps but they are so tastefully done. I like them.
Your comments may set off another hub-centric discussion. To me, the center only holds the wheel in place till the nuts get tightened. And it helps make sure the nuts come down concentric with their holes. But with a reasonable tightening sequence it should be no problem and the nuts, in any case, carry all the load while driving. I have opened up a number of other wheels over the years to make them fit and never had a problem. And many aftermarket wheels have a large center hole that has a lot of clearance around the hub.
I would have done mine on a lathe if I had access to one but loved the idea of being able to do it in my garage with the tires mounted.

I don't think you'll have a problem.

We do know that these companies don't go out of their way to machine things to these kinds of clearances/tolerances with matching bosses on the axles to save money. They probably have gone hubcentric to help eliminate warranty issues.

The great thing is since these wheels are 100% CNC machined at the factory, I'm sure the lugs will do the job.

 

Hoot,

Looks like you were able to find someone to lathe the hubs without dismounting the tires. I called a number of machine shops here in the Phoenix AZ area to see if they could open up the hubs on my first set of H2 wheels. To a shop, they all said that the tires needed to be removed first. Since I didn't want to bother with taking the tires off and then remounting the tires, I just bored them out myself. They ride very nicely but the expanded holes we not exactly aligned, requiring me to file out the excess material by hand. I am sure they are slightly out of balance.

Could you tell me what kind of shop you found that could do it with the tires mounted? I have another set of H2 rims with tires mounted on the way.

This makes 13 tires/wheels I have for my 1 month old truck. 2 full sets of H2's and the stockers. I started to look at getting the spare, and that would have run me $250 (rim and tire) or I could just buy a whole 'nother set for $540. No brainer for me.

 

We did it in the shop where I work. We used a machine that normally makes parts for the Boeing CH-47 Chinook, 777 jet, V-22 Osprey.

Its a big 5-axis CNC milling machine. I programmed a circular cut with an end mill.

Unfortunately the hourly rate on CNC machines isn't cheap but these wheels with tires mounted, can be set up on a regular non CNC machine and just bored out.

As you can see... it can be done, tires on..

 

CaughtinmyGrill,

You've got the right idea. More, more. I've got two sets and a spare and am looking for six more for my trailer.

Wetspirit, you must have one helluva trailer to be able to fit 3 bfg's a side! I am lucky to get 215/65/15's on my trailer, and it still rubs if I take a corner too sharp.

I am running out of places to hide the new tires from the wife. I hope she doesn't need to go into the sideyard for a tool this weekend or I'm busted. I just think that, with these tires alone running at $184-240 a pop, I might as well stock up for the next few years.

My only concern is that they won't hold up well in the Az heat while I wear out the other set. (I will clean out my shed and put them in there to keep them out of the sunlight.)

I wonder how the wife would feel if I stashed them in the master BR closet?

 

CaughtinmyGrill,
In order for your wife not to find out about your stash, you can store some (preferably 4) of those wheels & tires in my garage! Heck, I'll even rotate them for you using my truck, I'd say a couple hundred rotations a week (to prevent flat spots) oughta do it. I'm sure they'll last a lot longer up here in the cool pines of Prescott!!

 

CaughtinmyGrill,

I have a 48' box trailer/shop with three axles. I plan to save those precious 315's for the truck and run the H2 wheels with the stock Dodge 265's on the trailer.
These things are beginning to accumulate, maybe my neighbor can stash a few.
I wonder how long the tires can sit around off the wheels and be OK? Maybe I'll start practicing burnouts and do more sliding around corners so they don't build up faster than I can wear them out!

Nice thread, Hoot.

Thanks Maynard,

Here's the finished product...

 

Nice job Hoot! They look really nice.

 

Ok, I'm am idiot what does hubcentric mean? The hub supports the wheel?

 

It means the hub is a close fit to the wheel and is the centering device. The lug/studs are only for attaching the wheel.


Thanks for the complements Jerry but I have to thank the guys on this site that pretty much showed the way.
