Hey everyone,
I'm looking at tires and I found some that come in 2 sizes that say they "fit my ride". I'm a little confused about the sizes.

Front= 110/70-17 4.16  or 110/70-17 4.25 (I get this 4.16 and 4.25 is a width choice)

What is this?
Rear=130/70-17 7/32 or 130/70-17 9/32 (what do these 7/32 and 9/32 fractions indicate?)

EDIT *EDIT*
Never mind, those are the tread depth #'s. That was surprisingly hard for me to find for some reason.
Thanks
