The process goes something like this: 10 minutes to completely vacuum the interior and dust down plastic surfaces 40 minutes to completely wash and dry exterior 20 minutes to wipe down door sills, door jams, hinge areas, boot surrounds, engine bay 10 minutes to clean interior and exterior glass 10 minutes to wipe down all wheels and tire shine So all up it can take me around 1.5 hours to completely clean my car. It sometimes takes less, sometimes takes more. It all depends on how dirty it gets. The interior doesn't get too dirty, but the door sills get quite dirty. In the Summer months, my fortnightly waxing adds a good 3 hours to my cleaning process. I love keeping my car clean though. That said, the interior surprisingly stays pretty clean with the windows down. It's not like a dust storm going through the car or anything. It's just habit for me. The moment I start the car, my immediate first thing to do is put the front windows all the way down. Anyways watersmj, to keep a response to the original question so as to not deviate from the topic much, try looking into tires designed as a touring tire. Those are usually aimed towards comfort which also results in lower road noise.
