I was thinking today about how terrible the system for tire sizing is. There is no good reason to use section width and aspect ratio instead of overall diameter and section width when labeling tires. Also, it is a mix of metric and Imperial units. I've heard the argument that it makes plus one sizing easier because you can go one step down in aspect ratio as you step up an inch in tire size. However, it is even easier using a system of overall diameter and section width. Light Truck High Floatation tires already use this common sense system. Even if you wanted to keep metric units for O.D. and width it would be better than what we have now. Do you agree or disagree? Anyone know why we use the system we do today?
