uses 22 in tires, I have 3 NOS (probrably 40 yrs old plus) Sears Allstate matching treads, but can't find a current price to price off of, Also have a pr of matched 35 x 5's-25 in tire for sale. email@example.com
If I recall correctly, the '25 Pierce Arrow series 80 I used to have used 22 inch X 6.50 tires. Several other cars also used them (I know a small Locomobile did). They were an unusual size. I had to wait about a year for my new tires. The car had dual spares, and while I waited, two tires blew on tours leaving me with no spare.
I sure wish I still had that car. I still have two tires from it. They were probably made around WWII.
Drive carefully, and enjoy, W2
