Sadly, there is no such thing as the 'ultimate' bike tyre: choosing a model is always an exercise in balancing trade offs - spending more simply reduces quite how large those trade offs are.
Robust puncture protection, high levels of grip, and a long wear life generally come at the expense of weight, rolling resistance and suppleness.
The very best summer road tyres are typically geared towards those latter qualities, although grip is still a very important element - and a tyre that continually punctures will ultimately be slower than one with slightly higher rolling resistance and a more robust casing.
Equally, winter and training tyres are designed to be more resistant to punctures and to be longer lasting. The trade off is that these tend to be heavier, slower and less comfortable than summer rubber. With that said, the very best winter tyres are the ones which manage to combine those more rugged qualities with a fair turn of speed - fast is fun and all that.
So, those are the qualities to look for in a tyre, just don't expect to see the pinnacle of all of them in one single model!
