Are you looking for tire size? I am not sure what it is but they usually just go by diameter and width and the sidewall is what it is. I know newer tires have aspect ratios for the width to the sidewall. You're probably looking at something like 16 x7.00 but don't quote me on that. Just an example of the size. If you're wondering about whitewalls. I guess you could have ordered them but not likely anyone ever did.
