Tyres for E39 with Style 33 Turbines, £350 max

[sparks_E39]

Want some good tyres for the car, nothing really wrong with the ones I've got except that they are cheap ones at £45 a wheel and not all that good (previous owner). What I would like is to get 15-20k out of them at the very least whilst being safe with good grip. Can't really spend more than £350, what are my options?

[forsure]

Had cheap rubbish on the front of mine when I bought it, plenty of tread but hopeless in the wet.

Saw 'Falken 452's getting good reviews on here, so I bought a couple (via www.blackcircles.com ). £156 inc.

Very pleased with them.
