I once knew a web site where one could enter a stock tire size and a replacement size, and get an odometer and a speedometer conversion factor.  BTW, the difference is so slight for 185R14 vs 195R14 as to not be of practical significance.  But when folks go to the larger wheels and tires, it really matters.  mcneely
