Quick question, that confuses me.

Are the tire sizes different between the Sidewinders and the H-Spokes?
The difference between the front rims only is 10.4 lbs, and with tires the difference is still 10.4 lbs, which makes sense.
When you get to the rears, the difference in rims only is 9.2 lbs, but with the tires, the difference jumps to 13.8 lbs.

I know I'm nitpicking and might even be looking at something wrong, but it just caught my eye. :)
