Rim doesn't fit properly

[hrosenthal]

I'm having a problem getting my tire mounted. three of the tires fit on properly, and the rear of the rim is flat against the convex portion of the rotor.
One of them doesn't quite make it over the center hub to meet flat with the rotor.
I only see two possibilities:
1 - file the inner portion of the rim to fit over the hub (not a significant amount).
2 - somehow file the hub, which I am less inclined to do.
Any suggestions???
thanks

Had same issue on two rims. I don't know if your rims had already been machined out or not but mine had. Evidently on mine whoever machined them out did not take enough material out of the rim to go over the machined surface of the hub. I measured the diameter of the hub mounting surface and then the diameter of the rim. I used a small grinding wheel on a Dremel tool to open up the rim. I had to remove only a few thousands of an inch to get mine to fit correctly. Funny thing is if you are not paying attention and just throw the wheels on and tighten them up the rim will become stuck on the hub and you will have a bear of a time getting it off. Good luck.

Might I inquire as to the origin of these wheels?

They should be hub centric if mounting onto mustang spindles/axles.

If possible I would return the bad rims. They should fit like your two good ones do and it is important that they fit properly since this is what centers the rim on the hub. If you decide to do some work yourself, I would work on the wheel not the hub. And figure some way to take the same amount off all the way around the hole. Good luck!

Simple take a brake cylinder hone and hone out the wheel had to do that on two of mine.

Unacceptable, the rims need to machined to precise tolerances to avoid overrun/overrun on the wheels, not to mention runout. Remeber that you're building a vehicle capable of speeds/performance similar to a supercar. Don't do anything to that rim except for package it back up and return it to whomever you got it from.

I had a problem with interference between the rim and the Wilwood brake caliper and the actuator for the parking brake. I trimmed off the offending parts of the caliper and actuator. As others have said, I would strongly recommend staying away from any modifications to the wheels.

I would send them back or look at removing the interference on the none moving parts...it would be a whole lot safer. Carl

Just to ease everyones mind I contacted an Engineer at Halibrand Wheels (of which the ones I have are replica) and was informed that they machine the centers of their rims to have .005" to .010" clearance between the hub/axle and rim I.D. Their dimensions and clearances are based on standard Mustang hubs/axles. As the Engineer noted they use the lug holes to align the rims, not the rim I.D. If anyone has the Ford specs on the hubs/axles please share with us. Also any specs from other wheel manufactures would be interesting. Thoughts anyone????

I have the Halibrands and the Mustang spindles that both came from FFR. That's where the problem started. One of the four wheels didn't fit.

I had the same issue with my FFR Halibrands, Passenger Rear 10.5", when I first mounted them.
The wheel would not fully seat. I opened the hole, just a little bit, with a round hand file. Took about 15 minutes and they seat perfectly now.

I ended up using a brake cylinder hone as suggested above. It was a trace amount, but made a big difference.
