325s vs. 37s

All,

I've heard that 325s typically measure a touch smaller than 37s (and we all know based on brand, all tires that are the "same size" do not measure the same).

Any thoughts on this--do they measure smaller?

Thanks!!!

For example 325 is 12.8 wide..

So if you have a 325/70r17
It is a.....................34.91x12.8r17
If you have a 325/70r16
You have a............33.91x12.8r16

Download the app on your smart phone so you can convert back and forth

what I meant was with 17" rims, what size metric gets you in between 35s and 37s.

I've heard 70 is the spot, but not sure...

How wide are you willing to go.
