Great tires.
I love these tires. They look great on my truck, they are quiet going down the road and they are super stout. Have bought them a couple of times.

Great tire. Excellent price. Good for fleet replacements when tire purchases can become expensive

Very sturdy and rugged. Truck drives so smooth and very grounded. Highly recommend them. Performance overall is awesome.

Do not recommend vibrate and loud!
Very disappointed with these. Bought a set for a 2022 F250 and a 2023 F250. Cooper is a great brand and MADE IN USA is a plus. Always try to buy domestic if it's possible. I have had phenomenal results with the Cooper At3 XLT tires very smooth and quiet.Ordered the Stronghold AT for a slightly different look and a bit more aggressive tread. These ride and sound like a BIAS Ply Mud Tire. They are horrible and vibrate my teeth at certain speeds. I have contacted Cooper hoping they will do the right thing and let me exchange these for AT3's.

Best tire ever
I absolutely love these tires. They are great in snow, awesome traction in rain or slush. Look amazing, balanced out real nice. I have about 5k on them. I m definitely buying another set when these are done.

Terrible service from Goodyear service center
The tires were shipped in a timely manner and exactly what I wanted. The issue was the recommended service center Goodyear Auto Service - De Witt, New York. They refused to install the tire huge inconveniences. Amazon did refund the installation charge.

Great Tires!
I got four of these. Delivery was fast using standard and the product did not disappoint. My pickup looks like a whole different pickup with these beasts on. Super hunky grips :)
