It was time for new tyres (tires) - Michelin Pilot Sport 4. I decided it was also time for new rims as well, and found some 17" BBS wheels from a Carrera which had been used perhaps once or twice. Period correct for the 986 S. (I know some convert to 18", but 17" offer a smoother ride and better handling).
Also installed a new Alpine/Focal music system to replace the original Becker CDR220. What a difference!
