Put on as a super single on a Ram 3500
Size: 33X12.50R15LT 108R
Great traction given I only have 2WD, no incab humming or dog tracking sounds, and for as much as I run the truck tires have held up spectacularly with very little shown wear

Great tire
Size: LT295/75R16 128/125R
I’d have to say the best AT tire I’ve ever purchased. Put these on a 04 2500HD because the BFG were wearing out too fast. Got 10k on them and the still look new. Quite ride as well.

Great tires!
Size: 33X12.50R15LT 108R
The pictures with the lift and the white letter tires are the after, the picture with it low is the before. I love how deep the tread is and I love that the tires aren’t too loud on the highway. They are surprisingly grippy in the rain, I have to really get on it to break the tires loose even on wet pavement, really surprised me. I love the white letters, my only complaint is that when I went to scrub the blue off of the white letters it wanted to take the white off too, never had that blue stuff so hard to get off before. But overall great tires love them. ... show more

BAD ASS!
Size: 33X12.50R15LT 108R
33X12.50X15 Going to step up to the Stt Pro's when there available the AT3 XLT's are bad ass too! nice side bite and jagged syping by far better tires than Les Schwab could sell you!

Awesome ride both on and off road!
Size: 33X12.50R15LT 108R
I replaced my Cooper Discoverer STT's with a set of these and couldn't have made a better choice. I spend most of my time driving on asphalt or concrete roads and only about 15% off road so I needed some tires that would allow me to actually listen to the radio while driving. These tires not only provide me with a better and much more quiet ride, but they don't have to be re-balanced every 500 miles like the STT's. Well worth the money and I will buy these again. ... show more
