Stupid question, but I need to know. I have upgraded to the 6th gen 18's on my 5th gen maxima. I left the factory rubber (245/45/18) on the 18's. Now, I know there is a 2.5-3% of***e in my speedometer. Am I correct in saying that there is the same of***e in my odometer (it is also off 2.5-3%)? I wasn't sure how that was calculated by the computer. If someone can let me know I would appreciate it. Thanks in advance!

Yep, I had used that before. I know that my speedometer is off 2-3%. My question is does that mean the odometer is off that same 2-3%? Anyone know?

 

I would say Yes.
