I dont mean big little griff i mean i have dished rims in the back but more like regular van wheels in front. Look at my rig on my profile if at all possible zoom in on it and that will explain. I have a 97 f350 dually that all 6 rims match. Now when i do a google search for my rig or the incomplete chassis half it shows all the rims look the same.
Oh, sorry, I misunderstood.
What you have is not common but not uncommon either. Most manufacturers and owners try to make all wheels (tires and rims) match, primarily for aesthetic reasons.
It only becomes a problem in terms of the spatial relationship between the brakes and wheels. Typically not a problem with drum brakes but can be a problem with disc brakes.
Ideally, the rotors and calipers should be inside the rim, so braking force is linearly applied to the wheel, versus offset application. Motorhomes that use dual rims on the front have some kind of extender to maintain this relationship.
Using a regular rim on an disc brake axle designed for dual rims causes angular stress on the assembly.
Conversely, using a dual rim in the normal position on an axle designed for a regular rim often results in rotational and steering interference. The alternative is to invert the dual rim, again causing the tire to be offset from the brake rotor.
It'll work for short distances, like space-saver spares, but only for short distances and only until you can get to a repair shop.
(I have a picture that illustrates this but I haven't gotten my new computer to where I can upload it ... if someone really, really want to see the picture, I can rearrange my schedule to upload it.)
