Hello people have a question for you. It is about that I sold my rims with used tires and I only noticed after the purchase that a small nail head was in the tire. I had it looked at in the workshop and he removed it and said that it was only superficial and I should not worry. However, I did not tell the buyer about this because of all the packing stress. In the description I also wrote, that I bought the tires in 2012 and the buyer now means the production date is March 2011. I don’t know exactly about it either. In any case, he now threatens with a lawyer or I pay him 75€ pro rata as a replacement. Had also stated that I am a private seller and no withdrawal is possible. What should I do best?? Let it come to me or give him 75€? Would be great if someone could help me.
