Size of tires: 245/59 R 20, 102H DOT serial #: [XXX] The 2021 Honda Pilot came equipped with the tires in this discussion. At 30,000 mile check up at dealership, we were informed the 3 tires with this DOT number had dry rot and needed replacing. A fourth tire with a different number is in excellent shape. These tires are NOT on a recall list. Many of the Continental tires of this type have been recalled. Obviously since 3/4 tires are falling apart, it is not environmental or from road conditions or driving. These tires should be included in a recall. They are not safe and should last much longer than 30,000 miles of wear. We are going to have to replace them as soon as possible so they are not available for inspection. If they had failed, we could have crashed. There were no warning messages or lamps. I noticed they looked odd but it was just confirmed last week during the service visit that they had dry rot and needed replacing.
