1t adds to the circumference & so to the diameter, so perhaps, yes..
what is the difference? 1/2 inch.. the pitch between chain pin centers.
the chainring tooth has to be cut thinner for a 10 speed chain,
so ever-so slightly less surface to share the wear load of the chain..
you can add one of bike Friday's big chainguard discs to a triple
adding a spacer outside the outer chainring..
I have a chainguard outside the outer chain ring on a touring bike,
and a chain minder to catch over-shifts on the inside..
So ... no missed FD shifts.
