Can anyone please tell me how the tire attaches to the bolts in the running board or to the one on the cab side
I haven’t been able to see how others are done
Any ideas appreciated
Thanks

If the tire will go under the bottom attachment and it goes through the lug on the wheel there may be a missing piece that attaches to the top one and holds the tire in place. But that’s a guess. But it seems there is another bracket of some sort is missing wherever that goes.

The set up yours has seems reasonable.

Should just work by rotating the rim and align both the upper stud and the lower stud with two of the lugs on the rim.

The lower stud has two nuts, the rearmost is the stop nut, the front one removes to fit the lug, then replace to retain.



A different method on my cut-down, the farmer made an off-center board with fittings at each end from old gate hinges, the tangs of the gate hinge fit into two of the rim lugs, then the board is held with a central large stud and nut.

I think I see a rust hole in the running board. Is that an indication that the spare tire has been resting in the same spot for decades- bouncing, rubbing, collecting salty water, and finally creating the hole? If so, that should give an indication on how things aligned.

Thanks for the help
With the tire filled with air I am not able to put both bolts thru the mounting holes in the rim because the tire hits the bed if I try to rotate it
I was wondering if I only used the upper bolt if that’s all it needed
Did the bolt in the running board have another purpose?

If I use the upper rod then I might have to make a bracket to hold the bottom of the wheel
That would work best as the tire wouldn’t hit the bed.
I was hoping the hole in the running board was the answer to the alignment but I guess that’s just a character feature
I really like the idea of a wooden bracket maybe attached to the bottom bolt it the running board connected to the rim giving me 2 points of connection on the spare


There is a makers mark from the Collins carriage company on the passengers side
They were located in Camden no and also in the packard building in Philadelphia but I couldn’t find any sort of diagram or pictures
Thanks

That hole in the running board is pretty much inline with the bottom bracket which where the tire would be it seems to me. Whatever caused it has to be something to do with the tire. Since there isn’t any rust out besides there is interesting to say the least. Maybe there was a bracket of some sort that came up through the hole and over the years it just rusted out around it over time?
I don’t think there was any exact way the tires were mounted on aftermarket TT bodies or homemade ones so whatever would look period correct would be OK using what you have and just another bracket or something to hold it securely I would think.

If the tire is a "modern" replacement, it's most likely an "oversize" tire resulting in a taller profile which would throw the original rim hold down geometry out of the window !

Might have had 21" wheels and tires on it and was changed to the 30"?

Maybe laying the tire in a horizontal position and then turning It up and using a little force to do it to get the lug into the bracket and secure it with a nut? Maybe?
Use a measuring tape and see if the distance between the two lug holes on the rim and see if it’s the same between the two brackets. Just a guess.

I will be tackling this tomorrow when the humidity breaks
I did replace the tires this winter using the same size as the old ones

What are the measurements as shown below. If equal then the tire should mount on those lugs in that oriantation. If not what is the measurement for the bolt to bolt distance
