My main concern as far as tyres are concerned is that, even though my driving is mostly on dry roads, it will probably take a great deal of effort to wear out the Contis
That's the point. I understand your worries. No one would throw away some useful items. Now my Contis have 20.000km, they still look good with plenty of tread. You could think, why change them if you have so much tread. But this "so much tread" is the proof that they don't wear and, therefore, they don't stick at all. Next spring I will go for TTrac2.
