Best all round tyres?

[stevierst]

There can be a big difference in tyres but for your average road rider I think a lot of tyre confidence is in your head. If everyone says a certain tyre is great you're going to trust the tyre and be more confident and relaxed on the bike whereas if you think you've got rubbish tyres you're far more likely not to trust them and bail out through corners or get on the brakes early or stiffen up when it gets a bit wet because you've convinced yourself they're rubbish. In reality if you gave the same tyre to a really good rider he'd probably push them much harder than you would with no problems

Touche his dudeness! Couldn't have said it better myself!
All you need to do is look at the tyres race bikes had in the 60's/70's/80's, They were shit!  Our s/t tyres today have more grip, but 90% of riders can't get close to their limits, and on the road, SHOULDN'T get anywhere near that. It's all in their heads, and skills.
