well, the ideal conditions are of anyone's guess. and for the record i did them on straight road/stock car condition with pretty much stock tire pressure.
unless Proton messed up on what's ideal for the tire, then that's another story entirely.
and controlled conditions would refer to what? on a dyno ramp? imho public roads (especially in Malaysia) aren't controlled conditions at all.

Point being, ratings are there as a guideline, not a definitive indication of how the tires can do.
in fact not too long ago i've had a debate on TWI on the tire forums which ended in mostly an agree to disagree fashion (many notable points i must say).

although yes the tires obviously didn't fail/explode and i'm still alive today posting this very post.

davidke20 no you don't have to prove anything; in fact my post was merely to poke fun of how tire ratings can be very misleading (even from Yokohama or any other major brands)
Driving safely is more important after all, right? (yes i know, not convincing coming from me and all)

i mean, 360 TWI is supposed to be damn long lasting right? Well this is my CC5 after 11k km

granted, many users did report that their cc5 are very capable of 30-50k ++ km's.
in fact i had just met a customer at nestum 's place that replaced his set of cc5 after over 50k-60k km of primarily long distance highway usage.

and while it may seem unconvincing of myself to say that i don't particularly worship Yokohama (or any brand in particular), i happen to get most of my tires being Yokohama considering who i deal with for the most part. I get good pricing and most of the time in comparison of similar models of the tires nestum carries are not as attractive maybe because of pricing difference as he carries Yokohama more and maybe he get better dealer pricing with higher sales volume (the shop sign boards is a give away, no?)

Had i deal with other tire shops, i probably would be using other brands and you'd probably call me out for worshiping other brands and quite honestly i just find that very annoying. (which i get that vibe all the time in a particular thread unfortunately)

hell, i wanted to give a shot to BS RE-11A but to my dismay even Singapore distro do not carry them and the ones floating in SG market are all grey import (yes i've called Singapore Bridgestone directly)

What about Dunlop/BF goodrich? I know Dunlop's being carried by a particular motorsport shop in Sunway (need i say more? lol)
And BF goodrich is kinda non existent here.
(if you guys have lobang though do let me know)

Then there's Hankook RS-3
I've heard GREAT reviews from it and most feedback that it's even gripper on dry than the Yokohama AD08R

however, it's generally more expensive than the AD08R, and it last only half as much mileage/track days in comparison. (technically double the cost if you need 2 sets of tires for the same mileage/amount of track days)
even some of my inspira friends mentioned roughly "Korean tire more expensive than Japanese tire? wan meh?!" (i know, country/branding stereotyping isn't good, but hey it's not like i'm not being given the same treatment as we speak right?)

so where do i turn to in the end by process of elimination? There you have it.

Motorsport in Malaysia is still in a very sad state ever since i've begin to get involved in it, and until today i still don't see the light at the end of the tunnel
