Changing my Rims/Tires calibration/speedometer

[coleb423]

I heard that if i switch from my 18's to my 20's the calibration will be out of line. For example, The spedometer will be off, etc

Is this true? Please give me your input.

The rim size does not affect it as long as the tire height is the same or close to the same.
Thats why I am running 265/40/22's because they are the same height as the stock 18's

Click on links at top of page and you will find a tire size calculator.

I dont think they're the same size but thanks for you giving me a better understanding!

To be clear, the sidewall height cannot be the exact same size as the one you are replacing. The overall diameter of both the tires and wheels have to remain the same.

Like the guys have stated, so long as you get the right tires, the speedo will be fine.

~30.6" is the magic number I believe.

There is a module u can use to calibrate your speedometer because of the new tire size. Not sure if anyone has installed it here.

It is available via the mightycarmods online shop, they also have a diy video
