245/35 R20 Tires

Falken Azenis fk520 have been a great tire, noise level is not intrusive and they give a good return on fuel economy. These tires are very progressive and give good feed back. Having watched a back to back comparison with the Michelin PS4, the Falkens are punching way above their price range. If you want near PS4 performance at kumho prices, you won't go far wrong...will definitely try out the latest incarnation, Falken azenis R820 when the fk520's are done.

So far so good. These came in as OE in my audi s5. So I dont have experience with other tires in this car.

Still, the way I can turn my handles and not lose grip is impressive. I experienced minimal roll, I think the car also contributes a bit on this aspect.
When the tire is warmed up and is dry, I have much confidence to push.
I dont like to drive hard in the wet, so I cant say much on that part.

The wear is surprisingly not bad. Maybe its because I dont do track days.
I do push my tires/car time to time, launches and fast braking, driving in curvy mountain roads etc. But the treads seem quite ok at 16000km (~10000miles)

Comfort level, not so great, not so bad. But who would buy this tire expecting high comfort level right? At least its not destroying my butt, I am fine.

Would definitely buy again. But the price of these tires are quite through the roof in Korea at the moment. I really like these tires, but I will definitely try other brands for comparison as well.

Good tire for sure.

I've been driving these tires on my BMW 530d F11 2016 with 285/30-20 on the rears and 245/35-20 on the front.
Stage 1 tuned ~ 320hp & 650Nm.

For the starters, they are really good for daily driving.
My driving route is almost only highway and country road, yes I do some spirited/sporty driving time to time.
At very high speed you do feel that walls are bit soft, especially in the corners. Other then that, the overall grip is more than ok.
Been testing these on almost every conditions cold weather (except snow), summer, spring, fall and heavy rain weather.
The dry grip is good for commuting, as mentioned above they are bit soft at high speed.
The wet grip is one of the points were these tires suprise me for the price. Been on roadtrip in Norway were the weather was raining constantly and on the serpentine roads while playing with other cars, the grip is actally good.
The handling and feedback is good as long you don't drive them hard.

Noise and consumption:
Noise wise, they are not super loud, still comfortable but they have tendency to "hum" a bit when they are worn out.
Consumption: the rolling resistance is a highlight, for commuting they are perfect. Consumption numbers with these has been a pleasure.

The downside is wear/tread life.
That is the only one is thing about these tires that are big disappointment.
Manage to get out only ~ 35000km / 21700 miles and the rears are slick. And I only have them for 2 years. The front howevers have some life left, like 3-3,5mm maybe?
Since I have xDrive / AWD / 4WD, I have to replace all 4.
I do wheel alignment every 1-2 years depends on where I driving so I'm sure that the alignment is not the problem here. I do drive with 3 bars on the rears and 2.8 at the front since is a heavy car.

Maybe this is the price of buying a bit cheaper tires but Nankang according to my research use to have good tread life in general.
Because of tread life, I'm not sure if I will buy these again but I've been happy with these in general for what it cost.
