I am on my '01 Sport Trac. Not the same vehicle at all, but I wouldn't recommend it. Load Range D will tow whatever you can safely tow anyway if that's why you're considering it. I got them for durability off road as a trial. I will be getting LR D with the next set. I had to air down to 32 psi because at 34-36 it was jarring and I have a long gravel driveway. At 32, it's fine but the tires have started wearing a lot faster.
Not recommended.
