I have been buying these tires since 2008. I have a 2005 Toyota Corolla. With normal driving, I am completely satisfied. Good price in relation to their performance and grip. Because I drive a lot of kilometers, I change them approximately every 3 years or 70,000 km. Yes, they handle these kilometers with absolute safety (information from the official representative).

For their price, these branded tires have very good performance without wearing out quickly... I wear them on a company car that covers a lot of kilometers (Golf VII 1.6 TDI).
No comparison to the Continentals I had before, which had unacceptable behavior and wore out quickly..

Extremely flexible tires everywhere. Whether in fast driving or in everyday life, in dry or wet conditions, they never bothered me. I never had any issues with them, except for maintaining the correct pressure. They are also quiet and have a good price. I have used them twice on a VW Golf 7.5 DSG. I changed them at 45,000 km and put the same ones back on. My sister now has the car, but I predict that they will last much longer than the first set did for me.

So far I have driven 32000 kilometers with these specific tires.
Initially, in terms of fuel consumption, they perform well compared to the previous tires I had, they also reach temperature easily so that they can quickly deliver maximum performance.
In terms of wear, I believe they wear out faster than normal, although I change them every 40 to 45 thousand kilometers or every 5 years.
They have good grip on wet roads, although it could be better, but in no case will they betray you at normal speeds like the old Viking tires did to me.
Where it falls short as a tire and I wouldn't buy it again is the grip on dry and poor quality road surfaces. The tire easily loses grip if you accelerate and the ABS frequently activates during sudden braking.

Good evening
I was not completely satisfied with the goodyear tires
They were used on a fiat stilo and a volvo c30
In terms of grip, they perform well although we don't "chase" cars..normal speeds, so no significant difference compared to previous tires of another brand
In wet conditions, at normal speeds, there are no surprises so there is no particular opinion
What was noticed in both cars is related to comfort because they are hard and they bounce on potholes compared to previous tires from other companies
Especially in the stilo, which had pirelli tires, the difference is significant
Another thing is that they don't generate enough heat, for example on a trip with speeds of 120-150 from Athens to Patras when I got out and touched them, they were lukewarm to cold (winter day with 8 degrees)
Speed rating and dimensions are the same as the previous ones and on both cars
I have driven approximately 7,000 km with each set

I put them on 19/02/2021 because the mechanic from the tire shop recommended them to me and I really don't regret it at all (and I didn't know about them before to know their characteristics and comments from other buyers, etc.)
They are quiet and from the grip that I tested with sudden braking, etc., they are very good.
I will come back later once I test/drive them even more to add whatever else is needed, but so far I am fully satisfied with my choice and I would recommend them to others.
*edit1(23/02/2021): I forgot to mention that the tires are on a 2005 Skoda Octavia Tour and the car behaves very well on the road

I changed my factory Kumho tires on my Seat Ibiza and they are better in every aspect, especially in terms of rolling quality, absorption, and silence. They have great grip where you need it, and I didn't have any issues even in wet conditions. Highly recommended!

Mediocre tire in all aspects. I do not recommend it if someone wants to exert a little more pressure. It performs better in dry conditions than in wet ones.

Tremendously good grip for their price, very quiet, a step above all the mama kumho ecowing tires that my Ibiza had.
I haven't tried them yet in wet conditions, nor have I had them for a long enough time to see any wear, but the comparisons on the internet say that they perform excellently in both of these aspects.
