Hi! Yesterday I mounted winter bikes, the same tyre size as the summer tyres (245/20 and 275/20). I noticed during the first ride today (about 100 km) that the winter tyres are louder than the summer tyres and the steering behaviour is very individual. One gets an unsafe feeling when overtaking and forced gear type. The summer tyres have cold 2.5 bar inside, the winter tyres I pumped up to 2.7 bar and they reach during the ride about 3.1 to 3.2 bar. I still had at no m my vehicles a similar behavior (but I still didn’t have a 2 ton shell with 530 hp). Is it due to the tyre pressure or not yet worn-out release agent? Thank you!
