I had 10-ply Duratracs on an F-150 and loved them. Put a set of 10-ply on my 1st F-250 and couldn't get them off quickly enough. They were WAY squirrley with 0 load, just the truck, towing nothing, with nothing of note in the bed.
I had that issue with a set of Flaken AT's on my 06 Tundra. That truck did NOT like those tires! lol. I brought them back the same day and had them switched out to some Yokohama Geolander's. Which is a great tire btw...
