Did research and although none of the 'tests' actually featured these tyres I based my choice on the reviews and had them fitted just a few days before the recent snowfall - and so glad I did. Other cars, even 4 wheel drives, were stuck on the local hills but I sailed past with no problem. Massive improvement in traction on snow & ice - highly recommended.Can't comment on wear yet, but for the price an excellent buy.
There was Continental on my car and at first I hesitated too much about petlas/starmaxx. But it is half price of famous labels, and Ithink it is worth to try. It is very comfortable,silent and grips very well. There is no need to give to much money. The accuracy of tire tests are controversial. Who pays more, win the test. I highly recommend.
Last winter I used on my Megane4 HB. Tried them on snowy/icy mountain roads and had never problem about gripping. I can prefer these tires.
