Second set of these tires I’ve had on 2 different vehicles. Low road noise as long as you have a good alignment and rotate on schedule. They last longer than most A/T truck tires. Good traction on all surfaces and they look good. Just wish they put white lettering on the 20†tires.

Love these tires. They are not loud, have minimal to no vibration on the road and has enough grip to get me out of minor situations.I learned a long time ago that the heavier your vehicle is, the more frequent you should rotate your tires for longevity and even wear. Tire pressure matters too.

This is the second truck that we have put these tires on. The first was a chevy 1500, the current is a Ram 3500. They ride just a quiet and smooth on the 3500 as the 1500 which is super impressive. No vibration, little to no road noise, great in the rain, the last were great in the snow so we assume these will be as well. Another great tire from cooper, we won’t buy any other brand.

Better control, quieter, and more stable after 400 hundred miles of driving. Very Very good after that and very very attractive.

The stock tires on my truck wore perfectly and were whisper quiet but sucked in the mud and not so much in the snow either. I don't mud but I've been stuck in 2 inches of mud on a 1% grade. Dirt boat launches don't even think of it. These tires have been awesome. Sooo good in the snow. I thought my antilock brakes were messed up with the old tires. Just didn't have and traction.tires skidded making the antilocks work2wd in the places I needed 4x4. They were very quiet at first ( for an all terrain) but started to make a noise and loose balance as they wore. Ive had them since oct 2019 I have 35k on them still easily get another 20k. I rotated them every oil change about 7500 miles and balanced them twice. The reason I give them 4 stars is the noise and balance issue. They still ride nice but you can hear that tire slapping sound that you get with larger all or mud terrain tire after they wear.I treated my last tires the same and didn't have any balance issues. Its the price you pay for traction in adverse conditions. Honesty ill be buying another set when these go.

Very good traction in dry or wet snow........ wide tire is hard to balance....ore than one attempt requiring the tire to be deflated and turned 90 degrees and re-balance.
