original 1966 tires?

[jeeper44]

What would have been the original OEM tires on a 1966 CB77 Superhawk? I'm curious if the tires on my recently acquired bike are the originals-they are Bridgestones, and they are in amazing condition-no cracks of any kind (the bike spent most of its life in the back of a garage)

I recently removed the front tire from my 66 Dream. It was an original Nitto.

OTSU were used in the early years and I'm not sure if or when they changed to another brand. ....lm

I bought a 1974 XL 175 last year and checked the dates on the tires. The front was the original Nitto from 1974! The rear was a Bridgestone, dated 1981, The bike looked close to new and had 2500 miles on the odometer when I got it and I believe it is true. I was a little worried about the old tires so I had them replaced. I took it down to the shop I use for pretty much everything so the owner could look at the tires to try and order some that would be close to original. The owner (Billy at Cycle Goodies, he's the best) started laughing when he saw the rear but really started laughing when he saw the front! Both had small cracks though the front was worse. The tubes looked amazing after all those years but they were replaced as well.

I really doubt Honda used Bridgestone tires on your '66 Honda. Bridgestone tires were top shelf items at that time, so more common was Inoue and Nitto brand tires. I'm sure Honda got a much cheaper deal using those brands. If my memory serves me right in 1969 I bought a low miles 1965 Honda 50 Cub and it had Inoue tires on it. They were originals as it was hard to wear out a set of tires on a Cub in a short time.
Also from 1962 to 1971 Bridgestone itself was producing motorcyles and this bothered Honda and every other Japanese bike manufacturer at the time. Bridgestone motorcycles in the mid sixties targeted the American market more than their home market, thus Honda seen that as a threat as they were only recently established themselves in 1960. Yamaha, Suzuki and Kawasaki quickly followed in boycotting Bridgestone tires as they lost sales to Bridgestone Motorcycles. The boycott had significant effect as Bridgestone made a business decision by 1971 to stop producing motorcycles, and instead supply tires to the Japanese motorcycle and by now car manufacturers.
