I have posted full info in the wheel & tire section, but I think this type of info is just so important to us enthusiasts that I wanted to post the link here for more viewing.

Hopefully this thread will help people better understand the "it depends" answer when they ask about rubbing. It's all about tire shape.

Shape is definitely a factor, but all these tires have fairly similar geometry. It's not like one has a super square edge relative to the others. This is just the difference in actual width. The tread widths are different as well. Again, a minor variation in a given size can be expected, but for a 255 to be 13mm wider than a 275 is pretty surprising.

Thanks for posting this, it is quite informing.

Agreed.

However, not all 255s (or 275s for that matter) are created equal. From what I remember, P-Zeros have an angled shoulder making them less likely to rub given the spacer or fender application.
