Hi Marc

Are you referring to the "flaps" which are easily available at truck tire shops about $15 each.....

...or the solid rubber spacer that fits between the beads and keeps the run flat from collapsing......? these are hard to find and not necessary for a modern tube type re-installation.

I have found that the flaps, if old and near original, are usually very hard/brittle and not worth saving.....having the rims sandblasted and painted reassembled with new tubes at about $25 and flaps $15......
....... not having to change a flat by the road side.....priceless.

When you are matching tires for the final installation...... it may be worth while to take a measurement tape and measure the full circumference of the tires....... the closer they are to the same size the easier it will be on the U joints and generaly reduce loading of the drive train components.

Our experience with different bar thread tires......different brands and same brand different manufacturing dates of 9:00 16 tires..... as much as 6 to 8 inches difference on the rolling distances/circumference.... some where 1 to 2 inches taller and this on NOS tires...... generally speaking the original 1940ish V shape thread tires seemed to be a lower profile than the modern reproduced bar thread tires.
