Speedo Discrepancy

I’m currently torn between either getting 16” wheels (-12) wrapped with 265/70/16 or 17” with 265/70/17’s on stock OR suspension, no level or lift.

Does anyone happen to know how far off going with the 17’s would make my speedo? Would 75’s make it off much also?

 

Put in whatever sizes you want to compare.

 

I personally found that going from stock 265/65r17 up a size to 265/70r17 made my Speedo more accurate. If I were you, I would download an app and measure current accuracy. I bet you find that your 1-2mph/kph off (low) at highway speeds.

 

You’re assuming that stock your Speedo is correct which more than likely it is not. You need to first check if it’s correct or off and make your calculations from there.
