Hey Jim!
How goes it? I had the LTX on our F350 and had over 4/32" remaining tread at 43,000 miles. I wanted more tread for the AZ trip his winter so I replaced the orignal tire with the same new ones, I figure if I trade the truck this summer I'll recoup some of the expense on trade and get the benefit of new tread for winter driving.
I run the fronts at 65 psi and the backs at 80 psi when towing. If I think of it, when not towing I run the rears at 65 psi. The original tires had no uneven wear or other problems.
Dave
