Since starting topic, car has covered about 500miles on the part worn Conti2 tyres.
Like Dunlops, they to show a little sign of inside tyre edge wear.
After exchange of EM's with the 'Doc', took car in for a 4 wheel geometry check. Guy (who sorted my BMW when other so called experts could not) said GTi normally run a little neg.
On the rig it showed front alignment out by 0.5 deg, and one back wheel was off a little to. Not a lot, but worth it for peace of mind.
All sorted now for £58 incl VAT.
Will keep an eye on things for the next few months.
