Hello, I changed to new Nokian Weatherproof tires after just under 100,000km with a set of Goodyear Vector 4 Seasons before last winter. Now I have after only about 4000km 2 problems. 1: Are my front tyres inside strongly driven off and 2: Are the rear tyres between 45-55Kmh very loud. Can you help me what the causes can be and whether I can use the tires so further? Thanks and greetings Stegii
