Tyre threads are a bit like oil threads. No one is actually wrong because everyone is measuring things differently (and interspersing their comments with words like risk of punctures, crashing, danger, feel, grip etc. that they struggle to qualify in a meaningful way).

If a tyre manufacturer puts a wear indicator on their tyres then that is, for highway-legal tyres at least, the point at which a tyre could generally be considered 'finished' in an objective way (we know grip/water displacement can go-off long before then). Lisa has stated 12,000miles, which I imagine to be to the wear markers, and I believe that. A friend and I both had in excess of 10,000miles on our TKC rears (Africa Twins) and although it was not right to the wear indicator, I can't tell you how many more miles it would have done until it reached it. So I won't try.

Most people aren't too keen on the feel of flat-centred tyres but I don't think that is the important bit for overlanders. I want to know -> from a given sample of other overlanders, how far did that make of tyre get them on a bike that I can reasonably extrapolate to my bike/conditions.

I'm not saying that all tyres have these markers or that mileages on tyres should be a competition but I feel we owe to our fellow travellers to try to give information that we can qualify or make it clear otherwise.
