I'm using branded tires. I have used both Dunlop Geomax MX51 and Bridgestone M604. I get them from Chinatown in Bangkok and usually they are about 4kthb for a pair (front+back). Very happy with these two, both of them give very good traction when new. If I have to choose one, Bridgestone is slightly better. Mainly because of the front tire performance after it wears down, Dunlop tends to start to push when it wears down and you cannot trust the front end 100%. You can compensate this by lowering the tire pressure, but then the danger is getting a pinch puncture (which happened to me before).
