1 ton rear rims

[Mike 1948 1Ton]

Hello all, I have a question on dual rear rims. I have a 48 one ton with single rear rims. This meaning, that the lug holes on the rims are all 'coined', 'dished' or concave inwords, such that the lug nuts all snug in against the rim the same way.

My question relates to the dually set up. From what I understand, there exists is a specific dually rim such that there are 3 lugs 'coined' or 'dished' one way and three the other way on each rim, so that when they fit together to form the dually set up the rims fit or lock together.

If this is the case, would it work with the single rim on the inside and the dually rim on the outside? Meaning, keep the single rim that I have and get just the outside rim with the 'dually' lug holes.

After explaining all this I am thinking this won't work and that only the 4 rims with the special lug hole is going to work. My other question, is there any kind of wheel spacer needed as it would seem that the rubber would be touching as this seems like a pretty close fit.

Thanks for any help with this.

Mike,

No spacer is required but you must use the right size tire. The tires cannot touch. I don't believe the dished lug holes on a single or front rim will allow a dual rim to sit flush.

Here are some pictures of Dodge 1 ton dually wheels, 5-1/2" rim width. 4-1/2" are much more common and only for 6.00 or 6.50 tires. 5-1/2" will mount 7.00 or 7.50 tires.They have a 1-1/2" side offset so the tires don`t hit when bolted together. Yes you could bolt one of these dually wheels to your existing single style wheels - see the pictures, but the tires will rub. You need to use the correct dually rims on the rear axle so the tires won't rub. The picture of the front wheel on the truck just shows the single tire/rim flush (flat) offset-kinda.

Thanks, that explains a lot. This answers it then, there is the additional difference to the dual rim set up, that is the offset. I will need 4 rims not simply the 2 outside rims.

The quest then contiunes.

Thanks

If it helps dodge used these on dual rims for may years I had a 64 w300 which had that set up ,also had a 49 BD1 and they were the same size rims.

A friend just picked up a 57 Dodge 1 ton dually which has 17.5 inch rims from a 56 furd truck. Bolt pattern a spacing matches. These rims are not lock ring style which eliminates those problems. Been looking for a set for awhile now.

Also Studebaker and International used them up into the 60's. Most were 6 handholes but I just saw some late style 2 handhole style rims,
