Defective BF Goodridge KM3 tyres Michelin

Bought a set of BF KM3 Tyres which have have split and cracked despite having a +- 60 % tread left. The supplier advised me to lodge claim with Michelin which I did. Claim was rejected based on a visual only inspection. Michelin did not even bother to do proper testing despite my concerns for public safety. I have previously run over 10 sets BF Mud terains and all terains without issues. This is my first set of KM3's and i firmly believe that these KM3 tyres are defective. The tyres are clearly defective and pose a risk to public safety.
