Assuming you are still on stock wheels, you WILL be fine. I ran 32s on my 4x2 for months before I ever put my lift on and it drove fine. It shouldn't rub at all....and the 4.10 gear will help pull it better than my 3.73 did for my tires....good luck man!
I had those HT's on my '99 XL Sport. Believe it or not, I actually really liked them! I think they were the same size as yours. I remember seeing your truck in Manch-vegas. Mine lasted 50k miles strong, I actually traded the truck w/ the original tires on it! That pretty well amazed me! I didn't expect that out of POS stock Firestones..
