Conversely, I have 85 series tires on my dually and it rides like a buckboard. It seriously has 6 more inches of sidewall than the BMW and I feel every damn crack/hole in the road.
Right? By @Bewy ’s logic my ‘71 Ford with 35’s should ride like a cloud, I mean it’s got 2.5x the sidewall as my Duster. You'd think a tire with a 10" sidewall would absorb everything right? That's a lot of air!
It’s almost like the suspension is more important than the sidewall height with regard to ride quality! And we haven't even talked about tire construction or load ratings yet.
