If you'd like me to figure it for you, I'll need to know your rear tire size.

Re: which spedo gear do I use

that must be a typo, there's no such size. If you meant 245/50R16, then you can use a 38 tooth driven if you have a 15 tooth drive, or a 43 tooth driven if you have a 17 tooth drive. If you have an 18 or 19 tooth drive, you'll need to change it.
