I bought my Vauxhall Astra GTC new on the launch date. Its 19-inch wheels needed new front tyres at six months. The supplying dealer was unable to obtain tyres for the car due to the peculiar size of 235/45R19 and it took four weeks until I could get them. The car was at the dealership again last week for some warranty repairs and a safety report pointed out it needs two tyres due to punctures. They cannot supply me with tyres and Bridgestone are again unable to deliver them. I contacted GM in Luton to be told it’s not their problem. They don't have to ensure companies make tyres for the car. I refuse to pay £700 for Pirelli tyres off the Internet and then pay extra for fitting because Vauxhall supplied a car with tyres so uncommon it is not viable to stock them. Your views would be greatly appreciated.
