Having read a lot of the reviews on here, it seems that there is a great deal of variation in the experience of reviewers. Some find them to last for ages, some find them to die very quickly, some find they grip fine others are terrified by them. It would seem that either reading these reviews is not a very reliable way to get information or the tires themselves are very variable. I have no way of knowing which. I've had a pair of these on the front of my Fiat for about 16k miles - I believe they were original equipment and they suit the setup of the suspension. The ones I have were made in Turkey and I think are quite a soft compound. They haven't lasted terribly well, but grip quite well in the wet and dry and give way fairly progressively. I replaced a pair of Bridgestone B250s which I found to have far too little lateral stiffness and felt like I was on balloon tires.
I am happy with the performance of the P6000 and would buy them again.
