I have 205-50-16. I've been driving with them for a while now. I'd buy different ones, but don't wanna spend money on buying tires to replace tires that are still good. Although I do hate how these tires don't look as low profile. I didn't know anything about the measurements when I bought these tires, thats why I was too stupid to realize I was getting the wrong size. So my speedo is reading slower then what I am really going correct?? Or no?
