I went searching around but didn't really find the information. Is there a way to change the tire size in the software to correct for different size tires? I'm still running OEM sized tires, but I've been shopping for new tires and was maybe thinking of going to a 225/45-17 for reduced weight.
P.S. I got 69K miles from my original tires. Still had a tiny bit tread left before the wear bars, but the edges were worn down badly. I ran my tires at 49-51 psi all the time.
