Just thought I would post an update, it's the least I could do to thank you all for your posts.
Ok I need to change all 4 tyres 2 are illegal and 2 are worn all on the inside shoulder so I need the tyres, I'm ok with that I get all four fitted for £170.00 each plus vat then I need to pay £ 256.00 inc vat for wheel alignment, this cannot be done until tyres are changed as the old ones will give a false reading due to shoulder of tyre wall being weakened with excessive ware.
it's been suggested there may be nothing wrong with alignment as the tyre shows even ware across the whole of the tread apart from the shoulder, uneven ware would suggest incorrect or miss aligned tracking, they would also expect this damage to be caused by normal driving but on pothole infested highways( there are a few of them here) also kerb ing and impact to wheel would put this out if alignment. So there you have it. A car with a warranty and 3 years servicing attached to it costing the best part of a grand just through driving 10,000 miles pretty carefully at that
