MOT Failure - Opinions Please

the mot tester is a fanny and should be posting on here pedantically telling us how wrong we all are in our day to day driving habits.
although in real life its something you wouldnt personally pick up on,then you allowed the tyre man to fit an incorrect tyre 2 years ago and the blame will just bounce back to yourself.
yo be fair,its always common/legal/sensible practice to have identical tyres on the same axle though he also could have held the ticket and let the tyre man fit the tyre without failing you.
they probably didnt have 2 correct ones so just bunged that one on to get the sale.

take a chill pill and be thankfull that no kittens were killed.
