It's new tyre time and time to spend money

I've done a bit of searching and come to the conclusion that whilst some types of p zero aren't rated very highly on here the p zero nero seems better thought of.

Got my shortlist down to:

Vredestein Ultrac
Michelin Pilot Exalto (PS2 not available in size i need)
Pirelli P Zero Nero

Would be grateful if anyone could give any updated experience of the above particularly the P Zero Nero as it's around £40 per tyre cheaper than the other 2

Thanks
