That is what I have on Aldermog: in 20,000 miles the rears were 2/3 wrn, the fronts less than half. So I took the spare - unworn, unused - and purchased one new tyre so I have rears that are new and fronts less than half worn.
Clearly I need to try harder to wear them out so I can get 5 new winter tyres!
Perhaps a track day or two?
