Gritdog,If you look at the weight of all LT tires in the 225/75r16 size they all have a weight rating around 2500 lbs.The Toyos are 3195 lb weight rating.
That’s because the Toyos you are referencing are a different class of tire, a Commercial Tire.
They are designated with the letter C after the size but not to be confused with load range C.
But Toyo is not the only one that makes them. They are not unique to Toyo. You are just not comparing apples to apples by claiming Toyo is rated higher.
Tires load indexes are the same for a particular size and load class. I’m not actually aware of any differences. Yes you can get several different load ratings in the same size tire for many particular tire sizes. You could have a Pmetric/XL IE C load. Car tires, LT D and or E maybe F IE truck tires, and in a few sizes like the ones in question, there are commerical tires. Extra heavy duty for the euro style cargo vans like sprinters.
But you’ll never find an apples to apples tire comparison with different load ratings between brand or model name of tire.
