.....well, the tire is under the ADVAN range......moreover I have used bs Potenza re002, Michelin ps3 before......so without changing the way I drive......I probably can gauge the diff between the tires better......

It cant be worse than PS3 because that is what I used previously. This is better than PS3 in terms of handling. Really dislike how the PS3 keep understeering although noise and wet performance is good.

same here, was using PS3 and Primacy prior to this. I actually prefer Advan Fleva.

The saddest thing is the follow up took a month for us to get a respond from them. So the next step is that I will both take it to KPDNKK Consumer Tribunal. Next time we need to change the tires for our cars, no Yokohama for us.

Well if you read the reviews on those tires, especially the V12E2 & the new FK510, they're also considered very quiet, matching or even beating those so called mid-range comfort tires. The V12E2 was tested for only 67db by Car & Driver Magazine which is very quiet, plus it's also considered to have a softer sidewall (a forummer here who has used both V701 & V12E2 even said the V12E2 is softer!) so it's still pretty comfortable. So I'd highly recommend at least the V12E2 for comfort without sacrificing performance and yet all at a very affordable price, cheaper still than the V701. FYI I'm also using this tire for my wife's and son's cars and very happy with them.

Nope hasn't been asking around yet coz haven't need to buy yet too. 

still very difficult to find in market.been surveying this brand and model too.
