I have a 2006 Prius with the standard rims. A few years ago I read an article about changing tire sizes. I can seem to find that article, which cautions against going over a certain size due to excessive speedometer error and tire rubbing. I wasn't in the market for tires then, but I am now and can't seem to locate that thread. I found others, but they don't address the rubbing issue. Can anyone lend some guidance here?
