Tires Kumho or Cooper
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.
The V730s are bulletproof and I was able to get about 150 runs out of them before they heatcycled out.
If you're in arizona and it's not going to rain then go for the v730 all day. The v730 likes heat way better, and you'll get more runs out of a set.
Kumho V730s.
cooper tires are great, firestones will ride like shit (i have all season firestones ._.)
I bought cheap Kumhos once. Short life span and too slippery to drive on even though they still had some tread.
My KUMHO tires on my new KIA EV9 are totally bald after 16,000 miles. I suggest that KIA stop using KUMHO tires on their EV9 - why spoil an awesome car with useless tires.
