Hi all. Just did the ol' spin the tire and watch the drive axle to find out my rear ratio. Never done this before. Easy enough. What has me confused is the result. I got 1.5 to 1. Now I know this can't be correct. I'm assuming it is because only one tire was off the ground....maybe. Really have no idea.

Any thoughts here. Just curious what I'm doing wrong.

 

Thanks

So let me answer my own question for someone else who may get to this point. After a VERY brief internet search I realized with any open rear axle, which I guess I have, I need to rotate the tire twice. Or double my figures to get 3 to 1.

 

If I'm wrong please advise. Thanks for your patience.

You are correct.

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!
