2014 LE with premium 16" alloy.
Wondering the same thing.
I think the car is already calibrated for 17" wheels. I have 3 whips and there is one of those speed signs just up the street. My Corolla is the only one that's off from the "your speed is".
I have no other proof but when I'm going approximately 25, it's says I'm doing 21-22. Something like that. Could be the other way around. It's been a while since I've driven out that way, but you get the idea. My other two whips are on the money.
I am upgrading my wheels to 18", but wondering if 19" will fit? any photos? thanks
