Default 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!!!

The person who told you that has it wrong... In metric tire size the first number is the width and the second is a ratio of that and depends on the rim size..

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

you are absolutely correct...i fat fingered my question...my bad....

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...

A 325/75r17 is
36.19x12.8r17
That's pretty close to 37s
