OK, thanks. We have the same truck, but different years. Mine came with the exploding Firestone Wilderness tires. When they started delaminating, I took in the printed-out newsgroup threads on the issue to a dealer here (Earnhardt Ford) and they just laughed it off and said "it was only customers talking" and did nothing.The tires were later recalled by Ford after enough people died due to the problem (which was especially bad here due to the heat). I replaced those before the recall, with Michelins really excellent tires), but kept the bad tires around until the recall. Ford reimbursed me.
