Overdrive options

So, when you go to a tire store, you order your tires by o.d. size? If I went to my local tire store to order a 26.5" tire, they would tell me they would have trouble finding a rim that big. I think most people understood what I was saying.

When you are talking about RPM n gear ratios, you need the outside diameter of the tire, nor the inside. There are 24" to 30"+ outside diameter 15" tires. Saying you have 15" tires is useless in this thread. No one would understand how a 15" tire relates to RPM, it gives absolutely no reference.

Also… No mopar I’ve ever heard of cane with a 3.25 gear.
3.23 is a common ratio though.

I corrected my earlier post ,pertaining to the ratio. I really appreciate all the help .I'm learning a lot from this
