Yes, they are, otherwise known as Firestone RH-5's. The 2" wide flat strip near the middle is a "dead" giveaway. The problem with these rims is the extremely narrow locking lip that holds the two halves of the rim together. It's notorious for getting rusty, or being damaged during assembly, and blowing apart when the tube is pressurized. If a wheel has been assembled and run for a while, it's probably fairly safe, but few, if any tire shops will work on them. I believe there's a DOT regulation prohibiting them from being used on commercial vehicles, at least. Jerry

They only made the one LCF Series in 1955-2, the 5000 Series. The 7000 & 9000 Series weren't introduced until 1956 and with them was the start of the 6-lug Budd wheels for Chevrolet.

Great info Mike thanks. The rubber on the 55 is beyond bad but the 57’s have descent to great rubber although 6 lug axles. I’d like to swap axles and use not only descent rubber but 2 of the tubeless 22.5 up front. Hopefully they would clear the fenders

A 22.5" tubeless tire will always have an equivalent-height 20" tube type tire. They're close enough in most cases that a 20 and a 22.5 can be run as duals on the same rear hub. Jerry

What Jerry says is true as long as you remember that the number sizes don't match...the 22.5's need to be one size larger to line up with the diameter of the 20's
