SLK 230K R170 tyres

Hello, I have a VFL 230K since March 2000. the vehicle has very little Km (60K) and more than 10J old tires, which I would like to replace now. My questions would be: * Does anyone have experience with all-year tires on this car? * Which tires would you recommend? It is especially about adhesion in wet weather, since the car – without ESP – already has quite difficult properties in wet weather.
