That sort of strategy can get you in trouble. Tire pressures should not be adjusted for comfort. It's important that correct pressures be used both for safety in traction, braking, handling but also for safety in tire reliability.
One of the reasons for TPMS being mandated was the Firestone/Ford fiasco that was partly created by underinflated tires on Ford SUV's. Firestone blamed Ford for recommending underinflation and Ford blamed Firestone for defective tires.

Low tire pressures create heat, internal tire wear, excessive tread wear, unpredictable handling, poor braking. Tires can suddenly fail. It's safer, in fact, to slightly overinflate than to slightly underinflate.
Ride comfort comes from spring rates, damping, chassis design, seat design, and from tire design as well.
Unless you know what you're doing and have the capability to be able to determine proper tire pressures for the type of driving you mainly do then don't take it upon yourself to simply reduce pressures for the sake of a smoother ride. Proper tire pressures are intended to keep the tread flat on the road surface for traction and to produce even wear across the tread surface. It is also dependent on the load they have to carry and the speeds driven.
