When I looked at the tyres yesterday the very inside edge of the off side front looked very low, probably less than 0.5mm but I do mean only the very inside edge, the rest of the front tyres look to have 3mm + tread left yet. I guess it can't be bad otherwise I'm sure I'd have received an advisory on the MOT. I watched the fella doing it and he was very meticulous and it took about an hour.
I won't worry about tyres though. If it needs them then it'll get them... it's only the unknown and uncertain I worry about
