Just to add my input..................... I have a 54 plate 430 with 80k on, and after considerable research
I replaced 2x rear Bridgestone Turanza's with Falken 452's about 1k miles ago.
If one goes to comparison sites, the Falkens equal or beat the Turanzas at a much keener price and I would agree
that wet grip is better, rolling resistance is better, but they are slightly noisier.
As I'm not a price snob I believe better, cheaper tyres are well worth the noise compromise, which is un-noticable
with any audio playing.
