Speedo correction for larger tires?
When is it necessary to get a speedo correction for larger tires? I went from a 265/75 to a 285/75 both 16 inch. Would the height even change?

My truck has the old style speedo so I'm thinking that it is not re-programmable. My MPG has recently went down a little, so If I understand some of the posts correctly then the tires may be the reason.
You may be able to reprogram it yourself. I know you can do it on a 97 F-250 using the ignition and the odometer button. Check on dieselstop.com I am sure there is info there.
