I have been running my Cooper Discoverer AT3 XLT's for a few thousand miles now and have been extremely impressed. They handle the snow and ice of a Wisconsin winter with ease, clear well, and look fantastic to boot. Plus they're priced awesome as well. Overall a solid tire choice and I definitely recommend them!

Very quiet tire and was adequate in wet and snow, but with less than 30K miles and decent tread left, they hydroplane in light rain. I hit a light rain storm at 75 MPH last week and almost lost it. My only choice was to crawl in the right lane at 45 MPH to get through it. I certainly wouldn't recommend them.

I have been running these tires probably now for a little over 10 years give or take a little bit th

I'm happy with the purchase. Tires look good on truck and the ride is smoother. Hardly any noise to speak of! The tires are taller than stock and I can feel a slight wobble so I purchased a stabilizer. The outer edge of tire has a nice aggressive look.

I think these days people use these big tires for looks and do not actually need the tires to perform. They dont have the experience to realize what type of performance they are receiving from their tires. Having said that, I will say that maybe these tires are made for sand or light gravel. However, I live in an area where there is much snow, ice, mud, rocks and water. These tires do not displace fluid well and even pick up gravel and toss it onto my windshield, undercarriage and wheel wells. So after saving all summer for new tires, I feel now I need to purchase different winter tires for safety. They do great on the highway.

Best tires for the price

Absolutely love these tires. They have great tread pattern and durable wear. Great looking all terrain. Much quieter than my last set of BFGs. Ride is much smoother on the road and have had no issues off road. If you want a quality set of all terrain tires, these are the option for you

About Us
Anthem Off-Road was founded in late 2013 and started shipping product in mid-2014. All of our wheels are designed with feedback from a dedicated group of thousands of truck and Jeep owners.

All wheels, tires, and suspension parts ship for free within the Contiguous U.S. Shipping to other locations will be calculated at check-out. We are able to ship worldwide. With the size and complexity of shipping wheels and tires, always allow 2-3 weeks for our normal packaging and shipping process. If shipping outside of the Contiguous U.S. the transit time will be longer. Wheel only shipments typically are sent via UPS. Full wheel & tire packages are typically sent via an LTL trucking company. In either case, your order is insured against damage and you will receive a tracking number.

All wheels and tires carry a full manufacturer's warranty, please ask for additional information. The buyer is responsible for return shipping and a restocking fee (at the manufacturer's discretion) if returning without a warranty claim or a defect/quality issue. Any returns or cancellations after placing an order will carry up to a 30% restocking fee from the respective manufacturer (this includes wheels or tires shipped in from the manufacturer to our warehouse to prepare your order). Wheel or tire change requests made while the order is in progress may also carry a restocking fee based on where the order is in processing. Wheels cannot be returned to the manufacturer after tires have been mounted; nor tires returned after they have been driven on. If you have any concerns about fitment, returns, warranty claims, etc, simply share those concerns with our team of experts and we will work to find the best solution with you! SDWC is directly responsible and manages wheel and tire sales.
