The S is the speed rating of the tire; S is rated at up to 112 mph. It's just an average tire basically, not really used for extended high speed driving. It doesn't mean it would explode if driven above that speed, it's just not made to be driven beyond 112 mph for extended periods. A new Z28 would come with a Z rated tire which is rated for 149+ mph.
