A combination of don't care and haven't got a clue about tyres. I mean, they're just tyres, they're all the same anyway.................
The trend seems to be drivers that haven't got any clue or any interest in the car that transports them and their family thousands of miles every year. If it stars then it's all good. If it doesn't, just get someone to fix it. Just like they do the washing mashine.
Times are changing, cars are turning into white goods.
