In many countries, the law requires that tires must be specified, and fitted, to exceed the maximum speed of the vehicle they are mounted on, with regards to their speed rating code (except for "temporary-use" spare tires).
I see it as a safety factor - the speed ratings of most common tires (S or T, 180 or 190 km/h) are far beyond what most people will ever drive at. If this one is only rated to 130km/h, that decreases the safety factor.
During passing it's easy to push above 80 mph (the quoted rated speed for these tires) and for many freeways 80-85 is just the flow of traffic. Either way I'd rather not operate near the failure point of anything while driving long distances.
People may push to 90 or 100 for very short, infrequent periods. Even a 2002 station wagon is perfectly capable of doing that - you wouldn't expect the tires to just fail at any speed the car is capable of attaining.
In Poland the legal motorway speed limit is 90mph(which means there is a lot of traffic moving at 100-110mph). In neighboring Germany you can drive much faster than that. An 80mph tyre would be useless.
Even in the metro ATL area which is notorious for thinking the speed limit is a suggestion, the vast majority of traffic is moving under 85 MPH.
