How to date GT Tyres?

[monkian]

Does anyone know how to date GT skin wall tyres? Was there a production run over a few years on these?

I’ve got a pair, both 20x1.75 that are stamped. One has ‘K-69 20-E-751’ & ‘150181’ The other has ‘K-69 20-E-764’ & ‘150162’

Any ideas?

Here you go Nick. Unfortunately if they ever had logos they’re long gone

1987

Ok that’s Cool
How is that calculated Nick? Do you have any idea how long the production run for this type of tyre was?

Here’s a better shot of the tread pattern

That tyre pattern replaced the Shinko in 1987. Didn’t do them for very long at all.

Awesome, thanks Nick. I knew you’d be the man for this

I'd suggest a nice restaurant ... treat them to dinner ... couple of glasses of wine ... stimulating chat.

Roll them back to their place and see if you can come in for a coffee ...

Smooth but I think being dressed in rubber might call for a very different kind of night out
