Are there reproduction tires built that are dimensionally accurate as compared to originals? Early tire photos show a noticeably shorter sidewall as compared to modern equivalents. Even modern "smooth" white tires exhibit a taller or fatter sidewall. Curious whether one of the suppliers offer a more correct looking reproduction, or whether there are reasons why this is not done?
Most of the 30 x 3.5 and especially the 30 x 3s, are oversized and do not look correct compared to period photos. (However, 30 x 3.5 oversized tires were common from the 1920s forward.) The reproduction smooth tires appear to be ridiculously bulbous and oversized.
Just my opinion: appearance wise, the exception is Coker Commanders which I think are now called Coker Excelsiors, which is what my father has on his 1917 touring. He chose them because the of the 30 x 3s look the most correct. See below:
