i have used some of the budget segment china tires.. they are cheap.. i generally use these for abuse purpose, drifting and etc. i can say that some of these tires look like a popular make tire but the similarities stop there. These tires are ok ok on the dry, on the wet the character of the tire is unpredictable. not alot of feed back of the grip breakaway moment. so on the wet the grip is more like a switch instead of being progressive.

the upside of these tires is the compound is hardy, it can take alot of abuse and you get alot of life from em. hope this helps

i have friends on Giti, its pretty decent. the Sport S2
