Hello, I will get the next weeks summer tyres 275/35 20 inches on original 5 segment spoke rim 9.5×20″ for my Audi RS6 4F. I bought the RS6 2 months ago with winter tires, so I have no experience which summer tires are suitable. Which summer tire (factory) is recommended? Quietness/roll resistance/wear? Have had performance increased to 655 hp and V-Max suspension up to 340 km/h. The tyre should therefore be approved over 300 km/h. Thank you Thomas
