Plastic will cut rubber easy. Just because u bought same size tires doesn’t mean they are the same size. I just had that issue with RDR 33x12.50 tires vs a comfoser 33x12.50... the RDR tire only measures like 33x11 and the comfoser is a true 12.50wide.. I’ve also have had a few 305/40/22 tires in the garage from different manufacturers and they were all different sizes. You could have got some bad tires from the company, it does happen. But from those pictures, that’s a slice from either something in the road or your fenders/fender flares... I hope you get it figured out though.
