Tires Cooper or MRF

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 also got it when I was on my trip (3k kms on altroz racer r3). I stopped for alignment and found bubble. The tyre shop referred me to MRF district office. MRF office told me to contact car dealer for letter you just mentioned. While i just communicating for letter, told me.. not needed.. he just checked tyre tread depth, gave me a letter which tells tyre shop to install new tyre, got back to tyre shop, got it installed. Continued trip. Total time : 2 hours.

Mine was mrf and did not have a good experience. Within 1 month 4k km run tire burst in a simple pot hole with 33 psi air pressure

I've had nothing but problems with the road+trail AT tires. They have been rebalanced 6 times in the last 7 months. I've seen a lot of similar reviews saying the same thing. They replaced 2 under their warranty but the original 2 and new set are still coming out of balance.
