The wider your tires, the more prone they are to "tram tracking" on roads where ruts have begun. I've never felt this on concrete, but asphalt roads will have ruts from heavy trucks, especially in warmer climates. There's a ridge formed between the duely tires from the big trucks. I try to stay in the left lane as they are much less pronounced, but sometimes John Law doesn't like that and you're asking for a citation.
