What tire size should I get to go from 14 rims to 16 rims for my '99 Honda Civic Dx?

Stock size is P185/65R14 but I would like to go up two rim sizes. I would like to know what would be the best tire size be so that it doesn't affect my speedometer/ odometer drastically. I live in Southern California so if you could recommend which would be best that would be great!

Just the difference in the rim size will mess up the speedometer.

You can find this exact information on tirerack.com. Simply enter the information about your Honda and you will see the recommended tire and wheel size options in a 15 or 16 inch tire and rim combo.

Why?

Everyone else goes to 17" for this rig - 205/40R17 XL84 inflated to 42 psi front and rear.
