Larger Tire, Bigger Sprocket?

I don't know if one would notice the difference with the tire diameter

The stock wheel w/ tire measures 22.33" (18" wheel plus tire sidewall height of 110mm, or 4.33 inches)
Stock gearing is 14/50 or .28
With a 120mm sidewall (4.72"), the tire measures 22.72", a difference of .39 inches, or 1.75% over stock
To figure out the new gearing ratio for the new tire, I subtracted 1.75% from the stock ratio for a final gearing of .275.
A sprocket combo of 14/51 gives me just that, but a combo of 13/48 gives me .271 and the tiniest bit more low end with no problem regarding clearance, but I may have to lose a link in my chain.
So kids, what to do? Gimme some direction, I'm a ship without a rudder...boohoo ...SC
