After some thought have eventually changed to 225/45/17 tyre profile and on Monday had 4 Vredestein Ultrac fitted. Car looks great and tyres got loads of grip. There was an issue with the balancing though (surprise surprise!!) and after reading numerous threads came across this website http://www.balancemycar.co.uk. They supply this state of the art machine (Hunter GSP9700) and you can check on their site if there is a tyre depot near your gaff that has this machine. Well hey presto found one just down the road in Gateshead and just had all 4 wheels balanced for £16 and it is like driving a different car. Before I got a vibration at 65mph and the car just felt a little skittish, just not right somehow. Now it feels absolutely spot on and I'm well chuffed. Anyone in the north east having issues with wheel balancing I would recommend T.A.M tyres in Dunston, Gateshead. The fitter was just a young lad but I stood over him whilst he did it and he seemed to really know his stuff.
