I think he's trying to say you are battering your tyres. I've just reached 12k and finished my 1st set of rears, fronts are also original and still have about 5mm left
Wow thats long lasting tyres, I'm on my 3rd full set in 18 months and 11,000miles.
fcuk that. no need.
What you don't think tyres with tread level with the wear indicators should be replaced?

a trackday a month.

That'll do it
