Review on Dunlop Direzza DZ102 205/45 R17 88W summer by Micha Gozdalik ᠌

I took a new set of 1-1.5 years, everything was fine, after the car got up for a year, and last summer, when I started driving again, one fine evening, 2 wheels went flat at once in turn at speed! I thought it was a coincidence, it was no longer possible to determine the cause by the flat tires, and later, when I dismantled the remaining 2 wheels, I saw deep cracks from the inside all over the cord! How could this happen?
