I would never go below an H-rated...but its safe to say if you don't go above 120+, then H-rated is fine. The reason I leave about an 8-10 mph gap, is certain tire require you to add a certain amount of air in the car's tire if your going at higher speeds. All they indicate is the max speed of 130, but that means if your car has the highest recommended amount of air (in PSI) in it. for that reason, on the stock PSI, I would keep a 10 mph distance.
