I have 255/75-16 Widetrack Baja A/T's on my F-150, I have had them for 2 years and about 30k miles and really like them. Should still have about another 10k in them. I got them on a buy three get one free deal at a farm store, about $300 for the set.
Mine is the older style wiht diamond shaped tread, the newer tires have a different curvier style.
Due to the farm store sales I see a bunch of them around, my brother has them on his F-150 and my dad has the newer style (but in a 10 ply flavor) on his F-350, they are a great tire IMO.
They are made by Peerless, which like Dayton is part of Firestone.
