I have 24,*** miles on my Trail Grapplers and they are about cooked..... BFG KO2s are going on next.
On my three rigs I have run the following in addition to the Trails:
Duratracs
General Grappler AT2s
Terra Grapplers
Yokohama ?
Kumho KL78s
BFG Semi Rugged Trails....
Of those the most impressive on wear were the Generals, but they are on a lighter 2001 Tundra and they have about 50K on them and still have good tread left. The Duratracs were the best all around tire I had in load range E.
The Terra Grapplers were the least impressive in damn near everything and I pulled them off my F250 with only 20K on them and they are stacked on my driveway rotting away. Never hated a tire more.
The second set of Nittos wouldn't have been my choice for this truck and will be replaced soon.
