Saw this on the FarRider site this morning. Looking at the tyres size availability the ST1100 is still catered for though only in the standard tyre and not the GT spec.

The Bridgestone BATTLAX SPORT TOURING T31 (T31) is the flagship model for the sport touring category. This tire maintains the stability and wear life performance of its predecessor, the BATTLAX SPORT TOURING T30EVO (T30EVO), while also offering improved wet performance and riding comfort. The T31 decreases braking distances on wet roads and delivers higher cornering grip to contribute safety trip in unpredictable weather.
The new T31 tire’s tread pattern features increased groove ratios on the shoulder of the tire to allow for better water displacement and improved wet performance. The middle of the tire has a reduced groove ratio to contribute to increased block rigidity for shorter braking distance under wet conditions.
