New wheels and speedometer
My 2013 GT currently has 18" factory rims. I want to upgrade to 19". I went out to one of those tire size calculators and entered my old size and the new size.
It said my speedometer will be off by 1.7%. Meaning if it says I'm going 60, I'm really going 61. If it says I'm going 100, I'm really going 102.
Do you think this is really a big deal? The speedometer is very hard to read anyway, so I'm not sure one mph makes a big difference. What is your experience?
2016 GT/CS. Automatic, convertible. So far 100% stock!
