John, I'm not sure exactly what the factory width was however I just put 3" whites on my Sedan and it looks very good. I went with Goodyear Regatta 2's customized by Diamond Back Classics and was very pleased with the entire process. If you have any question on tire sources, types, etc let me know.

Blacat, my '56 4d Southampton needs new tires. I have 2-1/4 inch wides on now. What width did the '56s come with when new? John Santa Fe
