I have a 2005 Audi A6 and need new tires. I have Pirelli now but they dont handle the water well. I am looking for smooth tires and the dealer tells me to use continental at 800 or michellin at 1440. I have heard michellin is more expensive for the brand and makes more road noise. I have heard good things about the continental even though it is cheaper. My car is a 19. Any suggestions.
