Hello, have a question about 18 inch summer tires. Would like to exchange my 16 inch rims with Michelin Primacy this year for 18 inch (245/40 R 18). Is there a cheaper alternative to the Michelins in terms of durability? They are already very durable (and very expensive). I attach more importance to comfort and long-distance fitness as well as sportiness. Oh yes, the car is a Volvo S80. Would I look forward to a few infos.
