    grinding noise and rough ride only when in 4A

    I got my other pair of Pirelli's, and now have identical tires on all 4 corners. The rough ride is gone, and I didn't see the "reduced torque" message yet. As it seems, the difference in circumference between a Pirelli and a Hankook is larger than the difference between Hankooks with 20% and 80%...

    And there is the catch. Having tires of the nominal same size doesn't mean the circumference is identical. The difference between the Pirelli's I put on the rear and the Hankooks I had on the front axle is obviously enough to put unusual strain on the drivetrain. Now I am going to throw out the...

My problem, as I thought I would have explained quite clearly, is the exact opposite. Even if I appreciate that you try to...

    grinding noise and rough ride only when in 4A

    Hey guys, I have a grinding noise from the drivetrain together with a juddery ride when I switch in 4A (2020 Platinum). It started just before the last winter. Therefore, never used 4A all winter. Since the problem is present in 4A but it's all smooth in 2A, I don't think it is related to the...
