My 30x9.5 fits on it fine.  I did have to trim the rubber bump stops with my sawzall because of the number they were doing on the tire sidewall.  I also took the tire mount off and added a few washers to the bottom two mounts causing the bottom of the mount to kick out a half inch or so.

You imply that you ve' made rims by yourself?

Is there any pic of this rim?

Yesterday I tried mounting one of the 235's on the spare tire mount.  It did not come close to fitting.  The retread may be taller than a regular 235, but it wouldn't fit on the stock carrier at all.  I guess for now I have to live with an undersized spare.
