Oh, new car owner? Then yes, nothing wrong with stock primacies. They are often misdeservedly ill spoken of, but in reality are good normal tires. Less grip will net more playfulness/fun at slower speeds. They have relatively stiff sidewalls, good/sharp steering feel, wear well and help fuel economy. I wouldn't get them for second set because they are overpriced, but if you get "free set" with new car, imho best choice to wear them down instead of changing tires right away. Mentioned MPS4 will have higher grip .. but that will also mean less playful car, more "tramlining", at least in daily driving.
