Largest tires on stock wheels, no lift, but with 129 Load index (4080lbs)

I know there are lots of posts about tires, but can't find this.
What are the largest tires on stock rims that would maintain a 129 load index (4080lbs) or better, and without mods to the suspension?
I see some 295/70R18 with 129 load index, but that is it. Looks like the larger 15x12.5 tires have a lower load capacity (and don't officially fit on the stock 8" tremor wheel).
I need the full load index as I will carry a slide-in truck camper.

I ran Nitto Ridge Grapplers on my '13 in a size of 295/70/18 which is what you're looking for.

I’ve been looking around and finding a lot of the same things. For me personally I’m probably just going to stick with the OEM Duratracs unless I jump up to a larger wheel to allow for 12.5” tires … knowing full well that will lower the rating.

I know there has been a lot of debate about the Duratracs, but I’ve got 34k on them and can’t knock them.

I have 15,500 on my Duratrac and there over 1/2 gone. Not impressed at all with them. Seem like everyone is going Nitto. what type of mileage on them?

Nitto or Toyo can’t go wrong with either. I’ve ran mud’s and at’s 50k
