Finally able to update everyone who contributed to this thread. I had an important appointment today that I needed to keep and as I wasn't able to get a Goodyear delivered by this morning I had a local tyre fitter put a pair of Nexen on the car, normally they wouldn't be my tyre of choice but they got me out of a spot and so I'll see how I get on with them, having been on the motorway today I'm already feeling that they're quieter than the Goodyear, anyway thanks to everyone who contributed.
