in the US & UK civics come with 185/70R14 tyres (615mm)
195/55R15=596mm (-19mm from 185/17R14 - 3.09% too small)
205/65R15=648mm (+33mm from 185/17R14 - 5.37% too large)
why would you advise tyre sizes which are not the right size for the application?
on a 15 inch rims the 2005 civic would have to use:
all of these sizes would be less than 1% larger or smaller than the OEM tyre and therefore have no effect on the speedometer.
