Warranty for defective tyres?

Hello everyone! First of all I’m new here in the forum and need a sash! It’s about a guarantee for unusable summer tires. I bought the car 2 weeks ago. Test drive I did then on winter tires, because the car had no summer tires. The dealer promised me to make good used summer tires on it. So far so good. Said, done. The matures were totally in the ass, but also different (on the front axle). I noticed it. only when I picked up the car from the dealer. I immediately called the dealer and complained. ( Different tyres in front, vibration while driving, the right door didn’t close, by ZV. The dealer agreed to put other tyres on it and replace the door lock. Now he put new tyres on it (used ). At first I didn’t notice anything, except that the tyres were a bit louder, like with my old car. (I drove first week nic It’s a lot and almost only in the city center. In time the noise level has increased a bit ( or a lot ). Even if you drive in the city, you can hear it clearly. Now I have looked at the tires closely today. Shock! The tires are totally porous and according to DOT number: Front B.j. 2001, back 2006 ( but are also porous )! Either I was blind when I bought ( have still looked at them ) or the tires have disassembled after 2 weeks. And 11 years are of course also hammer! claim on tyre change ( warranty ) or the dealer sends me into the desert! Here are a few more pictures!
