Save your cash for now, you can keep your ps4 down to the thread wear indicator line. Despite being a tyre manufacturer, michelin is a strong advocate against changing tyres prematurely (albeit they standby this claim on their own tyres, not other brands). Your claim that it still grips rather well in wet despite quite worn down stands proof of their formula and engineering of their compounds.

On the other hand, i feel like the lower price point of the fk510 can change in the foreseeable future. The lower price point is likely falken's way of penetrating the market and create some buzz among the car community. Some months ago, i observe the pricing of the fk510 in singapore is going up. Either could be due to too high demand, or really, the "promotion" period is going to end. But i could be wrong.

Another alternative econo-performance tyre would be the hankook v12evo2. I'm using it now. Compared to the ps4, you would likely observe some improvement towards rolling refinement, but lose out a bit when comes to performance at limit. But still, the performance is still way better than the factory fitted toyo t1s.

You guys are talking about the price on Mudah? That seller jack up the price. I bought my rears from a different seller. RM670 vs RM720 by the mudah seller.

Weekend North South Highway, roads were damp. Performance is good.

110km/h I don't hear the tyre noise, hear more wind noise.

So far I'm happy.

Went to my usual tyre shop. My rears were gone, well worn and one side had damage -- this is not a fault with the tyre, but external damage that can happen to any tyre. My fronts were still good, shoulder wear due to poor alignment previously but not severe. I could continue using it, but I had to change the rear.

Thought about taking Falken FK510 again and just replace the rear pair, but backside itchy and I have been driving more spirited lately. So decided to go for PS4 for all 4 corners.

PS4 costs ~40% more than the FK510 for all 4 corners. Immediately, I noticed that the PS4 is more responsive in the dry, the FK510 is not slow, but the PS4 is just more responsive to steering input. And, on the same road, same tyre pressure, PS4 feels harsher -- I believe this is due to stiffer sidewalls.

Bear in mind I came from P7 RFT -> FK510 -> PS4. The FK510 was a definite improvement from the P7 in all ways and especially NVH because its not a RFT. The PS4 first impression is quicker/more direct steering response relative to the FK510.

Is the PS4 worth 40% more? I don't know, need to drive in the wet to confirm.
But based on dry performance alone, my answer is no, especially if you ferry people using your car, the FK510, despite "less" responsive, is not poor, and its not as stiff as the PS4.

I still think FK510 is a very good tyre for the price. But I wonder how does Sime Tyre Continental MC6 compares to the FK510.
