MOT Failure - Opinions Please

Load ratings are the in thing at the moment …We nearly sent a truck for test after it got it’s new tyres ,luckily it was noticed the tyre fitter had fitted the wrong rating before it went

Yours is a difficult one as you also mention it had previously passed tests with those tyres…The dealer should have noticed ,but the tyre company should know all about tyres and fit the correct ones to begin with…So the blame is to both dealer and tyre company …Both have failed …But that is only my opinion
