During the first few days of driving them, they had excellent driving behavior, as they say, suction cups. However, as time went by, they lost their grip, resulting in them not holding at all within a year! They don't wear out easily, but that is also their downside, even though the scooter is used daily. In short, they are tires for one year, after this period, they slip a lot, very much. I would never buy them again!
