Guys, I want to try Achilles ATR Sports. Any feedback on this cheap Made In Indonesia tyre?

Pls stay away from ATR Sport.
Its very unpredictable - once about 50% used, totally looses grip AND by 30% atleast there is tendency for it to explode. It does not have any sort of metal mesh from the mid to the side - my neighbour had used one on his altis and the bloody thing just popped at 30kmh. Thank god he was safe
Tyre review : Achilles ATR Sports 195/50/15
Car : Proton Satria 4G93. Tuned suspension, EVO Twinpots, aggressive alignment settings.
Mileage : 2000km
Dry Grip (7/10)Good. Not as good as as the premium ultra high performance tyres (AD07, RE001), but as a budget alternative, it doesn't embarrass itself.
Wet Grip (8/10)Very good in rather deep pooling water up to 120km/h, gets nervous beyond 130km/h. Grip on normal wet roads is commendable and progressive.
Ride and noise (7/10)Fairly good ride characteristics due to the soft sidewall (32psi), but somewhat noisy.
Handling Feel / lLateral grip Feel (6.5/10)
Rather soft sidewall and due to its very deep thread blocks, there is a lot of thread squirm leading to slightly numb initial response. Lateral grip is decent (better than the same class Bridgestone MY01) but do note an odd handling characteristic noted below under subjective observation. This tyres requires higher than normal pressure (big difference in feel going up from 30 to 34psi)
Durability (?/10)Too soon to say. But the thread itself is 15% deeper than my last set Michelin PS3. infact at 8mm+ deep, deeper than any other tyre I've used short of my snow tyres
Subjective observationThe main concern that I have about this tyre is the breakaway characteristics. On a turn, the initial lateral bite and traction loss is quite sudden and not very progressive. In short, the tyre does not like quick changes in slip angle and it is not as progressive in feel like the better tyres (Michelin PS3). However that said, once the tyre settles on itself, there is a fair bit of lateral grip to be had. This characteristic might catch people out, as the initial understeer may cause an inexperience driver to abruptly correct (or importantly over correct) for the understeer before the tyre can regain its composure. That said, if the driver can account for this and minimize big slip angle changes, you would be rewarded with good lateral grip previously unknown for this price range. Whether this is due to the deep thread or compound is not known. Will report back when the thread wears down.
The compound is relatively soft and is NOT a high temperature tyre. I did a stint at 200+ at "a private test track" and the tyre got very hot and very soft. Doubt one can run this tyre at Sepang for 3-4 laps before it melting and loosing grip. My car is 980kg... on a heavier car, this would be magnified. But in fairness, none of the tyres in this price range (under $200) will work at track conditions (my Silverstone Evol 8 had thread separation, rest melted after 5 laps). Yet to take this to the circuit.
There will be the constant worry about the high number of reported cases of the ATR experiencing catastrophic failure. However, normally, such a failure would be a result of loss of air. The ATRs do not seem to have a strong sidewall carcass so on loss of air, the tyre will collapse and the wheel will cut through the sidewall. The simple fact is, if you run a tyre with no air, the tyre will fail. Lack of air pressure will also increase the tyres operating temperature, sometimes to the point of failure. I've had tyres down to 15psi and the tyre looks normal. So check your tyre pressure regularly.
PS. I do know the rating means very little for now until I post my reviews of the other tyres I've used, but take it with a grain of salt as your car and your driving characteristics would not be the same.
Competing Tyres (used before, overall average, ranked top to bottem.)
Yokohama Parada Spec II
Achilles ATR SportKumho KU31
Silverstone Evol 8
Bridgestone MY01
It is quite close between the Parada S2 and the ATR. The Parada has higher limits more progressive and predictable in the dry, while the ATR is much better in the wet. The ATR has a symmetrical thread pattern vs. the asymmetrical Parada which places it well in terms of durability.
