### ⭐⭐⭐⭐⭐ Perfect winter time tire got mine just in time.
*by A***R on January 26, 2026*

Great tire, not loud going down the highway either!

### ⭐⭐⭐⭐⭐ Love them so far. Hoping they last.
*by M***N on May 25, 2017*

Just bought these, mounted them on some pro comp wheels, and so far they're great. Ive been playing around with tire pressure to get even wear because I want them to last as long as possible. Max rating is 35, but to get more even wear, I'm sitting at 28-30 PSI. A few things I've noticed that some people might be interested in before buying, the tread is softer than I expected but I have a lighter vehicle so I hope they still last, they make a little bit of noise on the road but its not bad at all, they're definitely not your average all-terrain tire, the spacing between the tread is closer to a mud terrain but the center tread pattern looks a little more normal, handling for pavement isn't as good as my old BFGs but thats not what I got them for, and I've already had plenty of compliments. I haven't done any serious off-roading with them yet, but I do plan to, and then I will update this review. I have driven them a little in the sand and on a few dirt roads, they seem to be extremely grippy. Update: The wheels that I put them on were 15x8, which caused the tires to bulge a little and could lead to pre-mature wear in the center of the tread. Luckily I spotted this early, ordered some 15x10s and threw those on (8.5-11 recommended). The tires look much better on those and are now touching evenly across the tread. I'm also able to air them appropriately to around 34 PSI. I did take them out on the trail also, and they are awesome! The trails were a mix of sand and mud, and these things were un-stoppable. I purposefully stopped half way up a sand dune to see if I'd get stuck, and they just pulled me right up no problem.
