Tire sizes ST235/85 R16 and 7.50-16LT are very similar. One difference to consider is the rim they'll ride on. The 235/85 R16 tire will fit 16 inch rims that are 6, 6-1/2, 7, and 7-1/2 inches wide. While a 7.50-16LT will only fit a 16 inch rim that is 6 inches wide.

If you want to know if you can use the 7.50-16LT, like the Kenda # AM10430, with your current rims you can measure them. Wheels are measured from bead seat to bead seat. Check out the video of the rim I've linked around the 1:00 mark to see it measured for a visual. If you have 6 inch wide wheels these Kenda tires will work great for you. They have a maximum capacity of 3,197 pounds at 91 psi.

The Provider # TTWPRG235R16 you mentioned has a maximum capacity of 4,080 pounds at 110 psi. If your rims are between 6-1/2 to 7-/2 inches wide these are the better option.

If your wheel is different than either of these widths let me know and I'll make other recommendations for you.
