I almost reported you as a spammer since most of your posts were not even a single complete sentence. I looked deeper and you appear to be a person or a really terrible AI, so I did not report your post. Please write out details on what your question is and why you are asking, otherwise most of the members here will not respond. (sorry to be a jerk)

You need to look at rolling circumference.
I would advise going to a tire manufactures website and looking up the sizes that interest you to see what their rolling circumference is. I like the Titan tire website as it has a large offering of tires, good data, and is easy to navigate.

Not sure if this information is what your looking for, but its damn hard to read between the lines of your question when there are no words to read between.
