It might have been an MOT 11 months ago when there was 1.7mm of tread on the tyre? 11 months on theres 1.3mm, making them illegal. And how is 3 points per tyre bullshit? The laws the law to be honest thou, 3 points per over worn tyre, first year 2 years of driving, points are doubled, therefor 6 points, 2 tyres = 12 points. Hard luck thou Mike, I hate it when you don't notice things on your car which could make it illegal/ unsafe. sucks so bad.
