Finally can update on this thread since my tires are almost up for a change. Overall, I'm quite happy with the tires for the price I paid and its performance. The noise level is still surprisingly good even when worn out, outperformed even my previous set of PS3. One of the tires (front right) has some tearing on the outer thread. Im pretty sure I have never driven fast on stones, otherwise all four tires will have the same cuts. Other than that, I really have zero complaint about them.

My cousin who had the same tires (after I recommended them) didnt fare as well as mine did. Im not sure whether its his driving style, allignment/toe problem, but both his front tires are bolded on the outer thread. Im pretty used to soft tires wearing out its outer thread faster but not this serious.

Im kinda inclined to try another set after the good experience but I will survey the market to see if there are any better deals. Saw Toyo TR1 and to be honest, the design simply scream "I'll be loud".
