How did we end up with such crazy tire sizing?

The diameter is in inches.
The width is in mm.

I figure that both should either be in inches or mm. Is there any rational why these two measurement units are used?

none at all. just one of those stupid things as far as i know... and then add in that the sidewide height is based on the width and the number

im not sure you have to ask the company.. example 245 is the width in mm, 35 is the % of the width that will give you the thickest of the tires, 19 is size in inch of the wheel.. I don't get it either...lol..

that's an easy one. It wouldn't sound right to say "I've got 559mm's on my escalade" in a rap song. I thought everyone knew that lol

Yo. Listen up. I'm going six-sixties.

And on a more serous note: wheel diameter and width are in inches. What if like tires, the width was is mm? Then people would not have to ask: Will 255 tires fit my 255 wheels?
