I find my ride a little bumpy with Geminis, but acceptable as it can be without air suspension. I've had 2 BMW X5s with air suspension, and 2 without, and my MY rides much like my X5s without. IMO, the combination of the Continential tires and their 104 rating, plus the standard coil suspension are really the culprits regarding ride quality in the MY with Geminis. Will the suspension break in a little? I'm not sure about that, but I've experienced night-and-day difference between Continential and other brands such as Vredenstein and Michelin when it comes to ride quality, and I expect the same when I swap these out.
I miss air suspension more than anything, and it almost drove me to an MX, but I am not interested in falcon wing doors. If air suspension is ever added to the MY, I will strongly consider ordering one and trading this one in.
