New tread patterns, both front and rear, provide more consistent wear characteristics and increased contact patch, along with better water drainage. The Angel GT’s profile was modified for a less rounded shape, which results in a contact patch that’s six percent shorter and 15 percent wider than the ST. In conjunction with new compounds, the shorter contact patch means less heat buildup and less movement of rubber over the pavement for less wear. On the other hand, the increase in contact width allows the GT to distribute weight over a larger area for more even wear. A new rayon-based construction works with a dualcompound rear and single compound front design (the front and rear shoulder compounds are 100 percent silica for excellent wet and dry grip) to provide better rigidity and more responsive handling while still offering good bump absorption characteristics.
