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

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 :)
