Why? Does the OP intend to drive his Sonata at sustained speeds of over 100 MPH?
Speed ratings are not necessarily one dimensional things where you only worry about the rated top mph. My car references an H-rated tire or above for good reason...an S or T-rated tire will usually not have the handling and/or load characteristics that make the vehicle handle in the manner it's designed. While a Sonata isn't a Corvette, it isn't a Trabant either and I wouldn't have the expectation that I wouldn't feel the difference in ways that matter to both me and the vehicle.
I think Nick had it right with his comment about the RT43 ( and his dislike for that tire ) when he said it made the car go from riding like a baked potato to a twice-baked potato. It's a similar concept if you go from a H or V-rated tire to an S-rated tire just because you're not going to drive over 100 mph....and that's your only criteria.
My wife's previous minivan, a Mazda MPV, came form the factory with "H" rated tires. Those tires had a very harsh ride. When those tires needed to be replaced, I had "S" rated tires installed. Not only did the van ride better, it did everything better...better wet traction, better snow traction, less road noise, better tread wear...putting exactly the same speed rated tires on for replacement tires is not always the best idea...
I wouldn't necessarily disagree...especially if the vehicle and/or your driving style can't tell the difference. However, you can get better riding tires by jumping categories and not speed ratings. I had an H-rated "high performance" tire...the category under UHP...that rode like rocks but switched to "grand touring" tires with the same H rating that rode significantly better with no real loss of performance that I could determine. In my experience, the idea of lowering speed ratings to effect a change in ride quality in most cases would be better served by the tire category vs. the speed rating. There are some really crappy S and T-rated all season tires out there in terms of ride and performance but "grand touring" tires as a class tend to have a good mix of performance and comfort. Speed rating isn't the defining component.
