I have 2 2018 Silverados.
One is a Double cab with 20" Goodyear SRA's . Not that bad of a tire but not that great either. Especially in the snow. If I get 35,000 miles out of them I'll be happy. I never run my tires until they are shot , they always have some tread left on them( 5/32"- 6/32" or more)
The other truck is a Crew Cab 6.5' ft bed with 22" Bridgestone Dueler AT RHS . These are pretty good tires all around I think . Better than the Goodyears. Decent in the snow and ride good on the highway. Maybe a tiny bit noisier than the Goodyears but not a lot.
I really can't tell the difference between the two trucks as far as the ride. Both trucks are Z85's.
Your results may vary. I live in Minnesota and we have had 2 ft of snow in the last two weeks.
I had 20" Bridgestone Alenza HL's on my last truck and I didn't think they were that bad either. But the Dueler AT RHS's are better.
