Okay i going to be getting rid of my 205/60/15 's and upgrading to prob around a 215/35/18 or something comparable. I am sorry if this is a stupid question but i don't know how to calculate which is a bigger overall diamater and by how much. If someone could give me a formula for future use that would be awesome.
