Make sure your suspension bushings/ball joints are fresh and also put on new bilstein heavy duty shocks on all 4 corners.....after you do that then ANY brand of new tires will ride like a dream. Picking a "brand" of tires won't make much difference if the fundamentals are not taken care of first. And I mean ALL of the bushings, not just the easy to get to ones. Front sway bar bushings, lower control arm bushings, guide rod bushings, rear subframe mounts, differential mount, etc.

With tires, the higher the aspect ratio, the taller the tire and the more cushion you'll get, in my experience and my customer's experience. Yup, it's not stock, but if you bump up the aspect ratio, then the ride will be noticeably more comfy.
