Hello, I observe an interesting phenomenon: the car tends to wobble / jump with the summer tires. The history. I bought the car last year. The winter tires were already raised (205/55/R16 from Pirelli). In the spring of this year I got the 235/45/R17 Conti SportContact3. Since then the car is a bit wobbly on the road. Up to 110-120 km/h it hoops over every unevenness, as if the shock absorbers were not in order. the door doesn’t close too gently, the whole car swings for a while as if it were standing on 4 springs instead of tyres. The tyre pressure is 2.6 bar. Manufacturer recommendation (both Audi and Conti) 2.3 bar (empty) to 2.6 (fully loaded). Ok, I mostly drive empty, but nevertheless, it won’t be at the 0.3 bar. I have read only good things about the tyres everywhere so far, both in test reports and in the A4 subforum. Could someone explain what this is all about? Gruss, l inch
