Difference between 225/50 and 225/55 tires

[1990MustangLX50]

Would the speedo be affected enough to matter when going to a 50 sidewall tire??

thanks

225/55/16's are the stock size and are 25.7" in diamter


225/50/16's are 24.9" in diameter

It's a 3.6% difference, so when your speedo says 60MPH, you are really going 57.9MPH
