18" Wheels Throw off Speedometer? Will going from 17" to 18" rims throw off the speedometer?
I'm going from 275/40/17 all around to 275/35/18 front and 295/35/18 rear

I do. ABS and Speedometer are fine. Exact sizes I have, too.

Here's the tire size calculator I use:

It looks like you're going to be just a little more than 1 MPH off at 65 MPH...not really a biggie...
