Factory load index rating for Liberty

Looking for this info via google and forums , I can’t seen to find any numbers.
I see info on the lettering “C” or “E” regarding sidewall ply but not the actual load carrying capacity.

For example one set of tires would be 107T and another place offers the same tire but a few bucks more for 111T.

What is the factory spec load range rating so I can calculate from there with towing needs.
Thanks

The spare on mine is a 104 load index. From the DOT date of 3903 I'm pretty sure it's original.

Here's a link to Tire Rack about load index:

OEM 225/75R16 Goodyear Wrangler ST are 104S rated.

Thanks guys ! That is exactly what I wanted to know. So 107/111 are both higher then factory. I needed a starting point and 104 is it
Again. Thank you !
