I punched that number into the tire size calculator against 225/50/16. The speedometer reading will be 3.6% too slow. The speedometer will read 60mph when you are actually going 62.1mph.
I guess this can be a good thing since your odometer will show that you've been driving less miles.
But yeah...it's all preference. Just feeding more information to help you make the choice.
