Hey Folks,
Slap me now, I know...
Anyway I have searched and seen the calculators etc, but I am trying to find out exactly which size of new gear to change the speedo reading. The 2wd that had the 14's with 3.73 rear end now has 30x9.5/15 and will eventually be shod with 235/75R15 when these wear out. I want to change my speedo to be as accurate as possible for the new 235's. I know that the 4x4's had 15 inch rims, would it be easier or even possible to just swap out that gear tooth with mine or is it easier to figure out and buy the new gear tooth that has been discussed in the tech section. Of which I am trying to figure out how to do that calculation anyway.
Any thoughts and assistance would be great.
