The Goodyear Tracker 2 @ walmart. I ran a set of these on my current truck, after about 30,000 miles they really sucked. I got stuck in wet grass (unloading a piano at my house, pulled into the front yard) snow was kinda nerve racking, no traction. When it rained (most of the spring) i lost traction taking off from a stop and spun a lot. I am not talking about a power take-off, i mean 2000 rpm and a slow let-out on the clutch. i ran them until the belts slipped and i got them adjusted out at walmart for the liberators i have now. (ps this all happened before i worked there)

I doubt you can get them for your truck, but the douglas brand name is REALLY substandard. they are cheap, but total junk. i would not even put them on a car to sell!

Edit: if noise is not an issue, and you need good mud traction look into mickey thompson and super swampers. Mickeys do better on the road, but swampers are kinda the go to brand for mud traction
