Tyre Wear Indicators / Wear Profile / Mot

I have the original Pirelli Diablo Rosso Corsa tyres on my 959.

The bike has done 3500 miles, and is coming up for its first MOT.

The tyres are nowhere near their wear indicators, but the centre is flattened off, to the point that if I look really close with my phone torch, I can just begin to see traces of the tyre thread lines just below the rubber in the centre.

I once got caught out on the Isle of Man, when the thread actually did show through on my Street Triple, as I'd relied on the wear indicators, which were still untouched after 8000 miles(!).

Now, I totally admit, I'm a cautious rider, and don't scratch it on the public roads, but I have done a couple of track days - where I am also a cautious rider

However, it beats me how anyone would get to wear down the markers before the centre of the tyre just riding on public roads, unless you never leave roundabouts.

I guess I'm ready for new tyres, but would the current tyres pass MOT in the state I've described, so long as the thread isn't actually showing through?

Cheers.
