Hi all,
I don't know when the tyres were fitted as they were already on there when I bought this bike just over 2 years ago and the previous owner (a vehicle mechanic) had it for a year before that and the tyres were on it when he bought it - so I can only say they've been on there for at least 3+ years. The owner before that, I was told, was also a vehicle mechanic who was fastideous about maintaining it, which by it's mainly unrestored condition I can well believe. The Gold Seal K70 was a 1970s manufactured tyre but I don't know when it was discontinued by Dunlop.
And guys, remember I'm not trying to sell my tyres, I just posted a picture of what I have on my bike.
I wouldn't chance riding with dodgy tyres, especially with my wife riding pillion and having had many British and Japanese bikes since my teens and being a motorcycle instructor for the RAC/ACU (Royal Automobile Club & Autocycle union) and the BMF (British Motorcycle Federation) Rider Training Schemes throughout the 1980-90s and and then as an examiner for the BMF I do take road safety seriously.
If you look at the close up picture I posted of the front tyre it looks new. The rear tyre is the same. Yes I know some may say looks can be deceiving but having restored quite a few of my own classic cars and British bikes I've seen a lot of ancient and dodgy tyres with minute surface splits, especially on the side walls, being a sure sign of age and perishing, so I examine my tyres carefully.
I can't really say much more.
