Well, if the compound is too soft, it also means that the tarmac is also like sort of tearing away the rubber compound as you go. :biggrin:

Sounds like a really good tyre. You are using them on all four wheels?
...
Hmm should not be torn away, but just chipping which is still not too bad, like my F1-D5 or PS3.
Yes it's an excellent tire in terms of performance. I'm using CSC5 at the front but the older version CSC3 at the rear which is also still a very good tire, just a bit lesser grip.

Time for CSC6 for next round......:biggrin:

You can rotate directional tyres left to right, but you have to pay more to un-mount them, flip them over, mount back then rotate....lol

Soft compound totally defers from air pressure loh! More air over inflate the tyres thereby less contact on the road. Less air under inflate center no contact will wear out shoulders....:driver:
Speaking about air pressure, I am still confused on what pressure should I pump onto my tyres. 185/60/14. Any recommended readings?

Air pressure usually I recommend 30 to 32psi for most sizes. The lower the profile actually need more air pressure. What does your car manual recommend? you can follow that too

Well, because my stock ones are 175/70/13 and now my current ones are 185/60/14, so I thought perhaps the stock rates may not be suitable?

Cannot, CSC6 only 19' above.
Sometimes I wonder why manufacturers do this by putting the minimum size to be this large. I mean, at 19" and above, they can't really be able to attract a lot of buyers.

Normally for daily use air pressure can range from 28 to 36psi.
I recommend 30psi because tyres being porous loses some air with time, so if use 28psi drop to 26psi is very low. From 30 drop to 28psi still ok....:driver:
As mentioned the lower the profile more air pressure. My 215/45R17 is around 33psi, my SUV 235/60R16 uses 30psi only.
Then again if the tyre sidewall is soft better increase slightly also.

They position the product as top class/premium product for high end market.

Change rims, lower the profile some more......lol:biggrin:
Naah no way! My car is not powerful nor big enough to use 19'! The max I'd consider for my car is 18', and even that must be lightweight ones or else I consider that a downgrade from my current 17' rims. If I have >500hp big car then I may consider 19' or else never! You may have noticed, I also don't easily follow trends of rims going bigger and bigger. I use things only if it's really useful/beneficial for me & my car and not those just for style/image but actually detrimental. Forms follow functions, not the other way around.

Just went to pump air at 32psi. I guess that is okay...

You forgot that he doesn't like very large rims for normal performance cars as he mentioned before several times. :biggrin:

Why? because premium model for top category only....:driver:
I guess that won't contribute to much sales.

You drive to station to pump 32psi, if tyres are warm you get 31psi cold, if hot probably 30psi cold only.....lol

I know bro. 6UE5t taste, trolling him only......hhahahahha

Their sales for small sizes comes from different models, that is why they have many models....You try getting Michelin PSS in 15".....hhahahahha:biggrin:

Huh? I think they are warm as I drove back from Kampar and pump at station near my house in Ipoh.

PSS also available in 15"? I thought that one is for large size.
