Thank you to everyone for the replies and info.
Before this goes any further I need to make a correction to my first post. Heather recommended the 245/70R-19.5” Toyo M608 load range H rated at 4940 lbs. I mistakenly put down 265/R-19.5” when it should have been 245/70R.
Big Toe, to your answer a question no I don’t think my rear axle is immune to failure. But I do think with my current set up the tires are likely the weakest part of the equation. Thank you for bringing up the other points. That is exactly what I was talking about and asking about. I don’t want to create more problems by trying to solve one problem.
Thanks,
