PP2 I think no more as my friend cannot find, so I recommend him Kumho PS31. So far to him it is ok...:driver:

PS4 not in Michelin MY website yet, but then like Conti website don't have CC6 but market have already.....lol:biggrin:
PS31 is UHP category? Now I think it is too difficult to source good tyres for sizes smaller than 15".

Hahaha, perhaps the website is not updated regularly.

Some models I heard bulge too, should be the older Ecsta KU31, after they switch production to Vietnam if not mistaken.
Extreme models like KU36 and V720 are used by many track kakis.....:driver:

Don't know, for Korean tires I would only want to try Hankook, the rest still a no for me. Just like Indonesia tire brands, I'm only fine to try GT Radial but not the others.

That tyre not for daily drive loh......:smokin:
If during wet, grip is totally gone? I saw before an Impreza WRX STI on road with R888 all fours...

How about Achilles?

So far based on what I read the only extreme tire/close to semi slick that is still decent in the wet is the Yokohama AD08.

Achilles I also don't really trust.

I think is when it is just wet not raining, but then extreme grips best with certain temperature. In rain they are cold so less grip....:smokin:

Most Achilles also not that good feedback.....

Then I guess max category is the limit to have good grip during wet? Actually, I'm still not too sure what tyre is categorized in max category. Heard before many from UHP, extreme but rarely max.

I thought ATR Sport have good feedback.

Yeah UHP & Max category often overlapping/mixed together during comparison tests, like some say PS3 is Max but I think it's still UHP. One clear example of max category tire is the Michelin PSS coz it's rarely included in comparisons with the rest like PS3, F1, P Zero, Sportmaxx, CSC5 etc. To me I I don't really bother too much between max/UHP, as long as minimum classified in UHP category then that's my target to use, more than enough for my normal sedan and normal driving.

I've seen a few cases of ATR Sport 1 & 2 after usage of say only around 60-70% and the treads already have like some separating layers showing, so not looking good despite treads still relatively thick enough to use at least another 1-2 yrs.

So, to conclude it, one can say that max is like a high end version of UHP tyres? Like perhaps Yokohama A-Drive R1 for UHP VS S-Drive for Max.

Sounds like ATR Sport's problem lies on the rubber compound/material used. I'm surprised that you are not showing much support your local tyre industry. :biggrin:

S.Drive is also still firmly in UHP, not yet Max category.

Yeah maybe, I don't know.

I'm a very objective and straight forward person! I support anything that's good especially those which are value for money, and I'm not hesitant to say something is bad even though it comes from my own country! I support GT Radial though coz I've used them before and fine with it. I also support those branded tires but made in Indonesia coz I know they're just as good, maybe even more durable considering how bad the road conditions are over there.

Actually F1 Asy2 and above, P Zero, Sportmaxx, CSC5 above are all in Max already. Yup, PS3 sometimes in UHP sometimes in Max, so somewhere in between....lol
Even like RE-003 sometimes UHP, sometimes Max....

Yup, they came out with max for high end UHP, those that really measure up to dry and wet performance.
Yoko A-Drive R1 is HP only, S-Drive is UHP, Advan V105 is Max

It is good being objective and not biased. Perhaps that is why you can do well in Malaysia. So far I have only heard of two Indonesian brand which is GT Radial and Achilles.

Never heard of Advan V105 before. Then where does Parada Spec 2 lies? Looks like these max tyres that you listed are not very commonly mentioned over here. Most tyres that people discuss here are either UHP or Extreme.

So, I guess to ensure good grip in all conditions on the road, the best one can go for will be max category?

Normally tyres without grooves are considered as above max already isn't it? Like R1R?

Achilles and GT Radial are represented here better so you know about them. There are other names like Accelera, Forceum, Neuton.
Most top tyres in every tyre manufacturer are Max performance category. Some have until UHP only then Extreme already so all depends.
Parada Spec 2 should be HP or UHP, but wet grip not too good.

Extreme need more rubber contact for extreme dry traction that is why it fares poorly in wet....:driver:

I just remembered one more. Corsa. Accelera I only got to know it recently from my relative's 275/30/19 on his 350Z. Forceum and Neuton, never heard before.

Do we have any extreme or semi slick tyres from our local brands like Silverstone, Sime Tyre?

I think wet grip depends on grooves to channel away water isn't it? Parada Spec 2 only has 1 groove... If so, then tyres like R1R certainly fares very poor in wet...
