Qualified tire management makes a further contribution to economy. This is also shown in the so-called pull point, the point in time when the tire is replaced with a new tire. A tread depth of at least 1.6 millimeters is required by law, but Continental has discovered that, once removed, tires still have an average tread depth of 3.7 millimeters. “A clear cost reduction potential lies here,” says Wilanek, “qualified tire management allows the tire usage costs to be reduced.”
