Tire test results with a set of tread compounds containing conventional carbon blacks, experimental ultra-high surface area I structure blacks at low dosages as well as silica indicate that ultrahigh structure blacks may be advantageously used in combination with silica. Correlations with laboratory test data are good with regard to rolling resistance but fail in the case of abrasion. Wet skid correlation seems possible but needs further work. In a second part the new generation inversion blacks are discussed with regard to analytical properties and reinforcement mechanism. It is shown that their characteristic in-rubber properties, i.e. low tan δ 60°C without changes in tan δ 0°C compared to conventional blacks, translate into a low tire rolling resistance without effects on wet skid properties and wear.
