You boys are hard on the tyres! I'd definately get your tracking/geometry set when you fit your next set of tyres. Laser track is only £25 and full geo about £65. Well worth the money. I'd be unhappy at only getting 8,000 from ps2's. I have Bridgestone potenzas on my caddy. They haven't been on long so can't comment on wear. The previous firestones that were on have done over 20,000 but that was just on standard steels (running 225/35/19 now)
