Hello, I ask this question in the Porsche Forum because technical questions are discussed in detail here. I have heard the following story over several corners over the weekend: An acquaintance has crashed on the highway, he had a tyre pitcher. He drove a large American jeep with winter tires. Since he had borrowed the car, he did not know that it was equipped with winter tires. The police now blamed him for not having to drive winter tires in the heat. Is this why it is a safety risk to ride winter tyres in the summer? Do winter tyres dissolve at high temperatures and burst more easily than summer tyres? Many greetings
