I had read many post about which tyre grip is better than the other .... ....
my 2 cent is get a better rotor, brake pad/shoe and flush your brake oil 20~30k interval then use any common tyre will do subject to your pocket money.
Most people "buang" at corner/wet road is not due to tyre grip but their common sense or the lack of it. Any reputable tyre brand is good enough. Use any common tyre with better brake system is better than fighting over which tyre to be use with spongy brake system.
Unless you drive 100km/h over the speed limit, any commercial tyre will do.
