I put these tires on my 2019 gmc sierra at4. I noticed a huge improvement towing with stability. The was no squirm in the back end and the truck felt much more planted on the road.
The downside of these tires are that they are stiff which actually effects your suspension tuning. You may notice the tires lose contact with the road momentarily at times over bumps.
I bought the same tires, 275/65r20 - been great all winter here in Alberta
Great tires, I have great luck with Cooper!
Got the same in stock tire size. I really like them. I think they're good tires and they've been wearing well on my mixed highway and city driving with occasional towing.
I put Cooper Discoverer Enduramax on it after purchasing last August. I love them. Quiet, smooth, have been great all around in rain, snow, ice, etc.
I like my cooper discoverer at3 4s a lot.
I have those coopers on the front of my jeep xj for a few years now. They are great.
I got 50,000 on a set of these and never rotated them. They were howling pretty bad because of it, and totally my fault. I went in to replace them and the tire shop said I had plenty of tread to go farther, I just couldn't stand the howl anymore.
I bought coopers about 3 years ago for my Silverado 1500. I will be honest this isn't an apples to apples comparison, I bought 4 ply (first mistake) AT3 4s's. They are cracking between the tread blocks on all 4 tires. Cooper won't warranty them saying it's just cosmetic, but they are deep cracks that go all the way around the tires between tread blocks on the inside and outside. I don't use chemicals or tire shine, and they are always kept at the appropriate pressures. They also lose chunks of tread every time i take them on the gravel roads in the mountains. I'm not happy with them at all, so my recommendation is to go with the K03's.
Just bought 4 new cooper pro control tires. Been driving for a week and they are a bit loud and have a slight shake or vibration. Already took the car in to double check balance and they said it is fine. I am still getting the vibration.
