I've run P Zeros, Falkens and Acceleras in the 4 years I've owned my 159Ti. Yes, there IS a difference between them in performance - dry and wet... But there's hell of a difference in price as well. I suspect that very few people get close enough to "the edge" on a regular basis for the full value of the (normally) £200+ P Zeros to shine through (well done on finding them at £194 as that's the best price I've seen to date). But for those who do push it then the choice is clear in order to avoid a phone call to the insurance company. For sure I would prefer to buy P Zeros if I was happy to cough up nearly a grand for a full set of new shoes. But I'm not - especially as you won't get much more than 10k miles on a front set even with parallel tracking. So Acceleras it is. They do the job just fine. And I rein in my enthusiasm accordingly.
