I have been reading loads since I started looking for a Vectra and thought I would share my finding's on the above tyre.

I run these on my 9-5 Aero (250HP HOT) and find them a match for the best premium tyres going, they are only available from Neo Brothers in Waltham Cross (No I have no connection living up here in Scotland!) but have to say they are very quiet have a great kerb protector look like Bridgestone Re-050's but for a 225/45 x 17 cost about £48 each
I got about 20K out of mine when Falkens lasted 9K and Conti's lasted 11K before so they are hard but decent!

If you want any info let me know and I will put up a link to the place.
