Regarding speedometer difference, are there any damages to AUTOMATIC transmission/the car itself if speedometer reads 2-3 mph slower than actual speed after upsizing rear tires?
Regarding speedometer difference - The typical allowable variation seems to be given as a % and I believe I've seen it as 2 to 3 %.
So if you're talking 2-3 mph difference at say 60 mph, that equates to 3.3-5% difference, which appears excessive.
Why not go to a wider rear wheel while maintain a closer matching diameter, by decreasing the profile ratio?
