I was looking at getting Yokohama dB tires but I have heard that it may give a 1% speedo error because they are not the correct 16 inch stock size. Any ideas on whether or not there is a speedo error for putting dB's on SE 16" rims?

I have 225 50 16's on mine and i think stock is 215 50 16's and it is definitely giving me a speedo error. I'm going slower than what the speedometer says.

 

225/60/16's get you 58.5 mph at a shown 60. This is by gps. My speedo used to be right on at 60 now its off some by gps......(auto) 1750=48 2500=70 3000=84 3500=96
these are with 225/60/16 toyo Fz4's
