I think you can get the tracking done at ATS for £25?
If the tracking is out, that could wear through tyres in no time at all. Have you thought about checking out any of your local scrappies for part worn tyres? I usually try to get the tryes from the spare wheels that have never been used.
I hear you on the roads - mind you, the state of the roads can be terrible over here as well.
Remember you can actually claim against the local council for vehicle damage resulting from potholes - just make sure you stop and take a photograph of the incident or you'll not have a leg to stand on.
I've not been back home since October but there's no place like home as they say
