What size tire fits now and what 650 tire would you want to fit?
Well, you see, um, the 1x11 eliminates the redundancy in the 3x10 gearing, plus it also eliminates the very low end and the very high end of the 3x10, which isn't really desirable or necessary. But since you have no FD on the 1x11, you bypass the FD adjustment problems that you get once a year. Granted, that's not a very good reason, but I like simplicity and the 1x11 doesn't require that I think about what gear I'm using; only that I know to shift higher or lower.
Your question about the advantages of 3x10 over 1x11 is good, as is the question about tire size.
