Seller advertised them as having 7mm of tread and having no damage. However the tyres only have 6mm at most and there is a scuff / cut on the inner side wall in which you can pull back the damaged rubber. It is not deep enough to go through to the inside though. I paid via PayPal and the seller has mostly good feedback. I have fitted them and so far no leaks but as 1mm represents about 15% tyre wear, would it be acceptable to ask for a 15% refund?
