I'm sure this subject has been beat to death on here, but I'm trying to figure out definitively if speedo recalibration is possible. With my new shoes I'm off about 7% at highway speeds and I'm trying to figure out a solution. Please don't state the obvious in that I should have factory size wheels and tires, who does that nowadays? I like the wheels and tires I bought and it's just one more issue I have to deal with. I install stuff that won't fit out of the box all the time and figure it out somehow. I've read all I can find on the subject and have many conflicting findings. Dealer can do it, deal can't/won't do it. Hypertech has a product to do it, but maybe not for Nissan. Independent shop scan tools can only access PID, not rewritable rom files. Has to be a way of doing it and I refuse to believe I am the only poor sucker that have run across this. Anyone have any input on this dilemma?

Try this:

There are other ways, usually a local speedo shop can make some adjustments or change out a wheel speed sensor but probably not enough to fix a 1" rear tire deficit.

I'm intrigued, I'll look into that a bit further thank you................-Curtis
