Nexen N Blue ECO 185/50 R15 Smart roadster 20,000 miles May 4, 2025
Cracks after 5 years. Grip in dry and wet conditions is okay, but not good. The inexpensive purchase is offset by rapid cracking. A friend of mine had small cracks appear all around his Nexen tire after just 3 years. Therefore, I don't recommend it.

Leao Nova Force 185/50 R15 Toyota Yaris 4,000 miles March 28, 2024
Tyres are better than i expected. They are quiet and comfortable, strong sidewalls (i bought XL), They have good decent grip in the dry.

bad points:
In 4,000 miles they are at 5mm. they were all 8/9mm new - and im not a harsh driver.
in the wet, sometimes i can feel it slide over and i have to make more of an effort to steer correctly. The road feedback is naff, you cant really feel much.

I’d rate them a 5 overall. cheap, comfortable, quiet. Its no gold star but they are better than i expected.

Nokian Hakka Green2 185/50 R15 Skoda 10,000 miles November 2, 2021
I've had the Nokian Hakka Green2's for 2 seasons now, I drive on a mix of city, country roads and motorway The tyres are not really budget and not really premium, it sits somewhere in between. The grip is really good, now I just have a Fabia so I don't take it on track days or drive aggressive with it. But at times I've taken corners at a fairly high speed and notice that there's still a lot of grip left, very predictable. In the wet it really shines, lots of grip and economic despite the higher resistance of water. The comfort level is not what i wanted it to be. I'm not really sure if it's the car or the tyres, but I think its very noisy at low levels of speed, so from 10-50 km/h. When the speed goes over 50 km/h, the noise doesnt increase, so it actually feels more quiet at higher speed, from 60-110 km/h. The tyres are very consistent and dont give much surprises, which as we know are the mark for good tyres. For me, I just want comfort and economic (not low budget) tyres, because I mostly go on long drives, so next time I'll try a different set of tyres, thats why I put a 5 on the (would buy again) option.

Goodyear Eagle NCT5 185/50 R15 Mazda Mazda2 24,000 miles June 18, 2019
The best of these wheels was the lifespan, in Bogota (Colombia) the holes are a nightmare but these wheels supported them very well for about 3 years, they are very resistants, but... I always felt uncomfortable because they didn't have a good wet grip nither dry grip.

Delinte DH2 185/50 R15 Honda Civic EG 8,700 miles December 11, 2016
The Tyres are good on dry conditions. Even on high Speeds (190 Km/h) the feel save. Only on Wet Roads they get a little slippy but not critical. After 14.000 KM the had around 5,5mm Profile. They carry me and my Family through Bad Roads in Turkey and i can surely say theay are good tyres for cheap Price!
