Has anyone here done some real testing on the following tires:
 

I'm wondering what sort of experience people have had on the cheaper tires out there both on the street and on the track.

I haven't been able to find a lot of useful / applicable review online so I figure maybe the forums are a good start.

Achilles ATR Sport
Sumitomo HTR-Z III
Sumo Akina ST-09

I have a good bit of street experience on the ATR Sport's but haven't had much chance to push them or give them a good test. I also haven't been able to gauge how they wear over time.

Please share your experience.
