Early 1928 Instruction Book mistake

[frank55a]

I reviewed about 200 factory photos for 28 and 29 and found several fairly clear tire sizes and manufactures. It seems to depend on the tire manufacture, ex. U. S. Royal appears to only show 4.50 X 21 in early 28 whereas Goodrich Silvertown tires were 30 (star) 4.50 - 21 well into 29. I have a very clear picture of an early 28 with Goodyear tires that are "30 x 4.50 - 21" (see photo).

The Ford Instruction book of 1928 was correct. You were wrong in your assumption that the book was wrong. Sooo . . . . do two wrongs make a right ?

It is common knowledge amongst tire historians that the 30X4.50 Balloon Cord is the correct tire nomenclature for the 1928 period. All the extensive literature of the time shows this to be so.
