After 4 years, the factory-installed ContiSportContact on my C-Max needed to be replaced. I studied a ton of rubber testing, including international ones, before making a purchase. I made the decision to use this specific rubber because it had won every feasible test over the previous two years (the model had only been created in 2022). In the city, there was only one set available. The fact that the 205/55 R16 91H was built in the Czech Republic instantly alerted me to the fact because of the sidewalls' softness (which makes it appear as though a plastic bag is being rubbed against it when a finger is applied). placed on alloy wheels and attached to the vehicle. In addition, two weeks of enjoyment have followed. Everything is as comfortable, predictable, and responsive as good rubber should be (my runs cover 95% of a very nice track, so the sidewall's softness wasn't particularly frightful). I entirely lost track of the existence of the rut throughout the course of these two weeks. It hasn't even been a month since I hit a pothole at 80 km/h on an unfamiliar night track, causing a 1-cm gap in the sidewall area. I halted a hundred meters away. The car came from the manufacturer with only a repair kit and no spare wheel. tow vehicle. fitted tires. The sidewall is completely torn up, and the keel is too large. The tire can't be fixed. The alloy wheel itself has no dents or scratches. Such rubber is not offered in the city (because it is too young and prime season). We'll have to wait a week while we order from Hong Kong. Great tires, but not for our roads, is the conclusion. Nokian Hakka Blue was required; at least it is readily available. By the start of the second season, I discovered that one tire had developed a crack along the tread grooves after (perhaps improper) winter storage. I preferred to purchase a brand-new one—the second one. Two tires from the beginning were nearly worn out to the marker by the third season (after 30 thousand runs).
