Nokian Tyres Developed Deep Cracks Despite Low Mileage

I purchased Nokian tires in 2019, but they developed deep cracks on the sidewalls and surfaces with minimal mileage. This poses a serious safety risk to passengers' lives. When I contacted the company about the issue, they directed me to the dealer where I bought them to open a service request. However, the dealer is located in a different city, and I don't have the invoice. All four tires are affected, and I'm struggling to get assistance from the dealer. These issues need to be known. The company should stand behind the tires they sell; these cracks occurred for no apparent reason.
