The doubters and 'will not touch with a barge pole brigade' are often flushed out, when they admit to never trying a tyre, rather they just go on brand snobbery and price, but those who have treid the tyres, I have seen a very high satisfaction level, 9 out of 10 saying they are very happy, and this mirrors my findings, I got my friend to switch from PS2's to Kumhos on his M3 before Christmas, and he is very pleased, and he really rags it, and his overall view is fantastic wet weather performance, not had enough warm days yet to form much else of an opinion.
I agree there are some peeps who may have their own prejudices, and who never actually try out a tyre (but that doesn't apply to me).
But one thing is absolutely certain, IF tyres like Kumhos or Eagle F1 Asymmetrics were as good as a few minor individuals 'claim' - then why are they
not offered as standard OEM equipment on high performance cars such as the Bugatti Veyron, Audi RS models, or Porsches (which ALL have the PS2 as OEM standard fitments)?

Both Porsche and Audi RS cars make no compromises - particularly in 'handling' where tyres are without doubt THE most crucial component.
The only reason that Goodyears, and the majority of the other tyres mentioned in this thread are cheaper than the PS2s - is simply because they are not as good as the PS2. And I am not just talking about actual 'performance' of the tyre, but also about the 'aftercare' of the actual tyre companies. The 'customer service' from both Michelin and Continental is light-years better than other 'premium' brand companies, including Goodyear-Dunlop!
As always though, ETTO.
