AZENIS FK510

Came with a used Mazda MX-5. End of life after 8 years, tire edge between wall and grip is drying out, cracks. Still decent dry grip, really sketchy in the wet. Tracking, tiresome to drive in highway speed in the wet at end of tire life.

The grip of the tyres on wet and dry roads is quite good, and these properties do not diminish as the tyres wear out. However, due to being a soft tyre, its lifespan is shorter than other tyres.

Excelent in terms of braking, grip, handling, noise and comfort. Poor wear.

Had the Falken Azenis FK510 run flats come already installed when I bought my BMW 420i. They likely had 6-7mm tread, and I have had them replaced now as 3mm tread remaining and 13,000 miles done. At this low tread, they were slipping/sliding quite abit now especially doing 70mph on motorway so safest thing to do was get them replaced and I've gone for another brand of tyres. The Falkens were good tyres, and never gave any issues. Never experienced a flat tyre or puncture even when going quite hard over potholes or rough road surfaces. I'm not a spirited driver but have gone up to 80mph and felt confident in these tyres. Have driven in the cold and warm temperatures over the last few years, and these tyres felt reassuring without any worry of aqua planning or spinning out of control. Overall, definitely a good tyre in my experience.

My car came with S001 RFT. This was my first "warm sedan". The ride seemed too stiff. Handling was uncommunicative; like on the rails. After they wore out, I got PS4 (non-RTF) thinking the road feedback would improve. It did not. Mind you, I do not do race tracks. I am driving exclusively in the city and on highways. I want the steering wheel communicate the interaction of the car with the road. The car just felt numb on roundabouts. The car was "skipping" in turns that indicated a firm sidewall and stiff tread.
So I got thinking. And I decided that the culprit was the sidewall that was too firm. I wanted to have a flex in the sidewall or in the tread lugs when I was doing turn around a corner or in roundabouts, the front tyres would flex, and would then push the car in the opposite direction. So I found from reviews that the Hankook and Falken UUHP tyres had softer sidewalls which, in opinion of some people, made them similar to the touring tyres.
With that thought, when the PS4 wore out, I got Hankook Ventus S1 Evo3. I gave up on my snobbery against "lesser-branded" tyres. Indeed, the Hankook had softer sidewalls, and handling had that pliable feel that I was looking for. The tyre performed 90% of the PS4 while costing 2/3 of it. I was pleasantly surprised with the Hankook tyre. It lasted 32k km versus 30k km for PS4. I thought I would be getting it again.
When the Hankooks wore out, I could not get it in my favourite online store. But it was OK with me, as I wanted to try the other hero of the crowd: the Falken Azenis. I had a choice between the FK510 and FK520 model. First, I set my eyes on FK520, as this was a newer model (therefore, it was better ?). However, further thinking threw an idea at me that the older model FK510 could have a thicker sidewall unlike the more modern FK520 that apparently was made with the stronger but thinner sidewall materials. My Hankook was of the same ilk, and I did not quite like it. It was too sensitive to air pressure. It depended on airpressure for the ride not on the stiffness of the rubber in the sidewall. The FK510 seemed to be of the older generation that I liked. So... FK510 was much cheaper in my favourite store (which indicated it was several years old). It was half price of PS4. The final convincing fact came from the review of the Singaporean gentleman in here, who said that FK510 had a better dry grip than FK520, thus he recommended it. So, I was set on FK510.
I got the tyres, and I was happy I got them. I noticed straight away that it had that "pliable" feeling in handling that I was looking for. Now, the road provided a lot of feedback to me through the steering wheel. (I think it also has to do because of a lot of sipes in the lugs as is compared to the larger solid lugs in FK520). The feeling was better than that in the previous Hankooks. The tyres were 3 years old, but that was OK, as I did not feel shortchanged in terms of the grip. The tyres were made in Japan. Also, the tyre design had a pronounced rim protector that I liked a lot. So, it turned out the best tyre for me so far on this car.
