I recently had Nitto Terra Grappler g2 275/60r20 installed on my '14 Denali. I too had concerns that the Denali ride and interior sound would suffer with an aggressive tire. I have put about 60 miles since installation. The Nittos are not as quiet as the OEM Goodyears but are much quieter than i would have thought they would be. The ride is similar to the Goodyears at this point in time. I'm not sure if either of these attributes will change as the Nittos age. The Nitto's look much better on the Denali rims than the Goodyears. As others have said, it is difficult to have an aggressive tread and quiet in a AT tire. Best of luck with your decision.
