Birth of the Dunlop K70 tire

[suzukizone]

Saw a nice old BSA V-twin in a TV show. It was set in 1929 but it had Dunlop K70 tires. I think this may have been an error but I might be wrong. I don't think that tire went so far back. Anyone have a clue, either exact year that tire hit the road or an idea or even an opinion?

No prizes for either correct or incorrect answers, just curious.

Thanks

Just a wild guess but probably late '60s or '70ish.

It's a TV show so it would be later and the bike fitted with the tire near the time of the filming, right? If that's the case I wouldn't say an error, just the way things go. I just put a set of K70's on my '66 Norton N15CS. They look right, sort of like a good pair of Frye harness boots, they suit the bike and the times, i.e the 60's, rugged and suitable for the job but pretty basic. I'd guess the early 60's but have no idea really. The old timers on the Norton forum would know I bet.

I strongly suspect that a set of oem tires for a 1929 BSA was not available for purchase at the time the show was shot.

That time frame is right, although I cannot say which specific year .
They were definitely popular at the time.

I had K70s on my Moto Guzzi when I lost a rear tire in Kansas City in 1972.
Had no problem finding the same model of tire there.
