Now I'm really getting confused. So,a 7.50-17 is a tire that:

7.50" width (sitting on the ground, measured horizontally one side to the other at widest point)

fits a 17" wheel.

So a 7.00-17 tire should be a tire that:

7.00" width (half inch narrower than the 7.5")

fits a 17" wheel.

I would think that the height would be the same on each tire. Or does the tire height vary depending upon its width? Most of the literature I see on bias ply tires don't reference the tire's heigth, just its width and rim size.

Am I mis-interpreting the numbers?
