Yes, agree with all the above, thoroughly subjective. The answer to 'are your wheel bearings OK' in relation to the Falken FK452 and Pirelli P7 noise comment, yes absolutely, I've replaced them! and the front and rear springs. The qualifier for the noise is that it happens towards the end of life of these tyres and I am sensitive to that sort of noise so it annoys me. As for outright grip, I should say that the vast majority of my driving is done on motorways and on cruise control, but I merge from M40 to M42 without changing speed in the outside lane (larger radius corner) and also M42 to M6 again without changing speed (around 75) the tyres I rated as grippy do not protest to this, nor should they frankly, but some feel decidely nervy and the steering has a tendency to go light and feel as though the tyres are about to fold under you. I also agree that the stiffer tyres (I'm using 99XL right now) do hold up better. I also learned that the Mohawk (possible Chinese ditch finders) are actually Hankooks second brand and made by Goodyear, not that that is a benefit, but the carcass will probably be OK. I also note that these tyres need less in the way of balance weights and roll very smoothly.
So I don't need track day type grip, I do need low noise and I do so many miles that I like to have good life expectancy. A balance that I have found with what I have tried and with the Hankooks and Nexens, though the Hankooks are better IMO. The Falkens were so soft that I have to overinflate the front tyres to get any stability or grip, at stock pressures they were shocking. I also like to know the car is still under me in the wet esp. as the M6 in the rain between J6 and J9 is like a lake in places, the Nexens are good when new but hopeless when down to around 3mm, the Hankooks are good as well, the Pirellis frigtened me, and I couldn't get the Contis (SP2) to stop spinning at the rear off the line in the wet, not good.
Strangely I quite like the Yokohamas which seem better in the wet than the dry but a bit pricey. I also like Dunlop Sp01s but they don't last me much more than 12K.
There is a compromise for everyone, it just has to be found by the individual and be right for them. I'd love to use the outright grippiest / best in the wet / longest life / quitest tyre, but I don't think it exists yet.
I also read the whatcar and which tyre tests and the last one I read rated a no-name Chinese ditch finder as the best tyre out there and ahead of the mainstream big brands. Wierd!
