After Continental and Dulnop, I decided on Hankook because of the price and positive reviews. I can say that I regretted it. In the city on worn asphalt it is a disaster. In 2nd gear it slips when starting on dry ground, while braking the ABS is activated where Conti and Dunlop never were. I have now driven about 15000km with them and I am constantly thinking about how to replace them. Of course the price of new ones is what is delaying the implementation. The car they are on is an Audi A4 B8 2.0tdi 105kW. I am 47 years old and I do not mind driving recklessly, but this tire is not even for normal driving. It is not for driving on wet ground. In the city at traffic lights the car in front of me always runs away 50 meters because I am not allowed to start normally because the ESP is going wild. Hankook will not be on any of my vehicles anymore.

Swap the OEM Toyo R52A (215/50/R18) to Prime 4 (225/50/R18). The R52A has just been droved for 21k KM (2 years old -- 4.3mm left) but it has shown some hair cracks on.
- Grip: Similar to Toyo.
- Braking: Shorter than Toyo, but probably affected from wider tire contact area.
- Noise: Significantly reduced than Toyo
- Comfort: On par to more comfort on Hankook than Toyo.

Still unknown for the longevity and prime 4 capability on dealing water puddle in southeast Asia.

Excellent tyre. As a summer tyre I normally use them from end of March to mid-November since here in Central Europe we usually have Novembers with no freezing temperatures so a summer tyre can perform relatively acceptable down to 7-10 degC. These tyres gives confidence and peace of mind, good grip, very good comfort, low noise, short braking distances, very good handling. This November is colder than usual and under 4-5 degC the tyre begins to show weaknesses as the compound is getting harder in cold. Noise increases and looses a certain amount of grip that warns you it's time to change. Still, runs safe just you get the feeling of these are not the circumstances the have been designed for.
The only weak point is the wear. Two seasons (20.000+ kms) and more than half of the tread went away. So I expect 30-35 k kms as lifespan. My former Goodyear lasted longer.

Normally daily drive in an excellent grip and silent, wet road grip also excellent.
Just when wet road drainage not good, but still have grip on it.

I have 20.000 miles and I m close to limit of red tread 1.6 mm with tyre pressure above 33 PSI .

I never use the grip and silent tires on my Honda civic turbo.
At the good condition road,I only can heard the sound of engine and wings! That’s excellent
And I feel on the dry road, the tires also is grip

I felt that I ought to have felt bad about owning them right away. I was impressed with this set of tires after the break-in time. The tires on the front and back are both inflated to 33 PSI. They performed excellently in spite of the rainy and dry weather. Crisp cornering and little body roll. Smooth on a smooth asphalt, low frequency sounds on a rough one. The mileage increased little from 5.3L to 5.8L/100km for whatever reason. Without a doubt, I will suggest it to my friends.

First two years of using grip was good on wet and dry road. After 2 years grip on wet is very bad. Tires rapidly change quality after 20000 km which is not normal for me. Prior this tire I was using Pireli P7 which have much better performance after two years of using.

Recently had them fitted to replace my worn Toyo Proxes CR1s that came with the car. Handling on dry road was excellent and wet grip was whole lot better than the CR1s. First impressions with the tyres are impressive so far. Looking forward to see how it performs down the road

The tyres are good but to hard and uncomfortable to drive, you feel every bump on the road. Would not buy again.

Very happy with dry handling, not bad at wet handling. Around 10 degrees they become very hard and lose all their grip on the "cold" and wet. Other than that, 6 months on them, around 10 000 km, driving RWD with around 200 hp, living in Croatia (very dry and hot summers) I am very pleased with the price range and quality. I would by them again.

Purchased this vehicle interstate and drove back home through heavy rain and the cheap tyres fitted aquaplaned badly i needed a quality premium tyre and the hankook ventus prime 4 delivers a safe surefooted drive in all conditions
