Advancetrac? differant size tires

2013 Gt, I looking at buying a set of staggered set AMR wheels from American muscle with 255/40-19 and 285/35-19, the rears are 26.9" and the fronts are 27.17, will this effect my Advancetrac/Stability Control??

Probably not, but your speedometer will suffer. Either have a dealer adjust your PCM or purchase a tuner to do so yourself.

I compared to the original tire size and its -1.5 percent, so i guess that means my speedo will be off about 1 mph at 67mph

If you have a Bama tuner we can correct that for you. If you don't, I'm sure you won't even notice that small of a difference!

I hope this helps. Let me know if you have any questions or need some assistance!
