I ran milestars before. The chinese milestar.
Their tires are great for tracking. They're infused with way more silicone than regular tires, as a result they are more sticky, durable, and can handle much higher PSI. They're talking about 60-70k mile range, but I would believe ~50k miles for regular use. Still not bad.
Their grip is out of this world (I'm not kidding), and they are rated V for speed (150 mph, which you won't easily reach). Ride quality is softer, tires are lightweight, and they stick to the hand, almost as if it was pure silicone; stopping power in the rain is great.
No visible cracking or tearing in the 2,5 years I've been running them. Wear was minimal at ~22k miles.
Of chinese tires it's said that they run best in the rain, and once they start wearing, they run better on dry roads than brand tires, due to their rain grooves narrowing out (basically becoming slick tires).
They only have a few cons (cons some other chinese tires might have as well):
1- They have very thin sidewalls, making the ride very soft, and rob some power from the engine causing lousy gas mileage. They need about 10PSI more than regular tires, or inflated to their max PSI (45) to have a 'similar' gas mileage (less than 10% lower MPG) and ride quality than brand tires (say 'Goodyear' or 'Michelin' or so). The higher profile tire, the lower MPG and PSI these tires support. The stock ST tire size from them supports up to 45PSI.
2- They don't have a steel belt in them, but more like cloth/fiber, which makes them more susceptible for punctures.
3- Over time the rain grooves narrow out, and will cause more hydroplaning. Especially for a car as light as the ST, and especially if you're looking to widen the tire width! (It wasn't too long when hatchbacks were equipped with much narrower 175/65's or 175/70's).
If you have more than enough power, but need better cornering, I would say give these a try!
