Thanks Gary. Sounds like I'm going to have to run dedicated summer/winter wheels if I go staggered. Can someone please explain what the big deal is with staggered wheels when they only extend the outside edge by 3mm? I know, bigger contact patch for grip. But performance aside, is there any other reason?
