It's not the top speed, it's the tire construction. An H-rated tire will have better construction than a T-rated tire. H-rated tires (and above) generally have additional cap plies that reduce the tire's failure rate in service. H-rated tires in general will offer better structural integrity. Many people only buy H-rated tires and above, for the safety aspect, and I think that's a good policy in general. Especially if your car originally came with H-rated tires, and there are GOOD H-rated tires available for your car, it's a no-brainer to me.
With the possible exception of the new (and relatively untested Continental), the Michelin will be your best choice of those...but they're all good tires with proven track records.
Agree - I have been a slow learner but after a lifetime of experience and vast reading/research on the subject I now believe the majority of drivers would be better served by using an H-rated tire. It is all about the internal construction which allows for the higher speed rating - not the speed rating itself.
The superior construction means you seldom will experience the internal belts slipping in the tire and that means less problems with vibration and even outright failure. If you are lucky these problems usually will not show up until the lower rated (e.g. S-rated) tire is a couple of years old but when you consider the life of the tire it is worth paying a bit more for the better tire IMO.
This is even more important if many of your miles are at interstate highway speeds vs. less than say around 65mph around town.
