These tires are much more "lively" that the Goodyears I had on previously. This is very predominant when driving on a concrete road surface with "draining tracks" cut into it. Here the car swerves from side to side and seems out of control.
The tire is made from a material that appears very different from traditional tires. Sidewalls are very thin. I have damaged 1 tire sidewall beyond repair just by driving on a slightly rocky area, and I have had 2 punctures/flats in just 3 month. First ones in close to 40 years. This makes me believe that these tires are not particular robust.
