Two tires that fall on each side of the extremes of section width (for example) might cause a rub issue with one where the other one clears...always been the case... |
No one follows any standard. You don't have to take my word for it, show up to your local tire shop to see the truth. Even the exact same size from the same company will have much different dimensions if you compare their Summer tire to their Winter tire, to their All Season tire.
There is no standardization.
