it will be great if u can share your tyre size and your car model.
For V12
Fuel Efficiency :C/E
Wet Grip: A
External Rolling Noise: 70 db/ 71 db/ 72 db

For PS4
Fuel Efficiency :C/E
Wet Grip: A
External Rolling Noise: 71 db

have you check on the euro rating? is it the same? I pull out all the rating on the model but different size will have different rating so i am not sure about your size.

It's quite a simple decision actually. Just answer this question: do you have the budget for PS4? If you do then no need to think much, by all means just go ahead with PS4 coz it's well proven on average as the best tire in the market now. If the answer is no, then go with the V12E2 coz that's the best value for money available now in Malaysia (unless later we can find the new Falken FK510). I'm using the V12E2 now on my wife's car and I'm very happy with them, excellent dry performance, good wet performance, and low noise level too which is quite a rare trait for this type of tires (UHP). I'm yet to try PS4 but compared to PS3 which I'm also using now, I can really say the V12E2 is every bit as good if not better on the dry and lower noise! PS3 is probably only better than the V12E2 on aquaplaning resistance. So I don't think you would go wrong with choosing the V12E2 either. FYI, in the latest test by Car & Driver magazine the V12E2 even managed to beat the highly regarded Goodyear F1A3!

In summary your decision lies on how much budget do you have?

Do you know where can I get a good price for hankook V12E2 in Shah Alam area?

Well to me the V12E2 is not noisy anymore and it's also tested by Car & Driver Magazine for only 66db noise level which is very low already (normally even comfort silent tires are tested around 67-69db). Anyway since you have budget for PS4 then just go ahead try that coz it's widely regarded as the best tire now. Note though that during that test by Car & Driver Magazine, the PS4S was more noisy than the V12E2!
