Yes you are right Don; the 1900's came with either 400 mm wheels or 16" x 4" wheels. I had a set of steel rim 16" wire wheels years ago and traded them some 400 mm Aluminum rim Borranis. Andro's car probably originally came with the 165 X 400's (actually the tire size).I am certain I've read somewhere that 1900's could be had with 16" as an option. Wonder where I saw that? Oh well.
I am searching for 1 or 2 165x400 borrani wire wheels with alu rim
did you buy NEW Borrani's or did a rebuilt of your old wheels ?
Another Question :
Do the 1900CSS ( tipo '56-'58 ) have original steel rims or alu rims ?
Ciao!I am certain I've read somewhere that 1900's could be had with 16" as an option. Wonder where I saw that? Oh well.
Fusi wrote on p.453 of "Tutte le vetture dal 1910" that 1900 Sprint and Super Sprint wheels and tires were either 6,00-16 or 165x400. For other 1900 models (and 102 /106 cars), he lists only 165x400.I think there's some confusion about the sizing. Tipo IVs, to my knowledge, call came with 16 inch wheels. The Michelin X tires on my newly restored original wheels are identified as "165 R 400." Whether 400 refers to the diameter in millimeters or not is up for debate but it's possible. 16 inches=406mm, so perhaps the Italians just rounded down?
