How to Achieve Most Comfortable Ride?

[RockyDijohn]

When it comes to tires, I know there is a tradeoff between comfort v. performance. My wife's medical conditions require that we focus on her comfort.

I understand high-profile tires will help. What would be the highest aspect ratio to get for a Tahoe or Yukon? Do I run the risk of voiding the mfr warranty if I deviate from their stock 275/60R20SL tire (60% aspect ratio). I should not get the highest aspect ratio possible, should I?

And what about suspensions and drive trains? What should I choose to get the best possible comfort?

Pushing the height (and/or width) of the tires can lead to fender/wheel well liner clearance issues... But you could always go down in wheel size and increase the sidewall size and maintain the stock tire height. That would provide the most comfortable ride.

Incidentally, the limiting factor for going smaller in wheel size is brake clearance. I think it may be that 18" wheels are the smallest that will clear the stock brakes on the '21+...

I bought a new 2024 Tahoe Premier 4WD with the factory installed 20-inch wheels and tires, and the magnetic ride control shocks (no air suspension).

The vehicle is extremely smooth and comfortable. It is the first vehicle I’ve owned with the magnetic shocks and they are remarkable.

You may want to test-drive one with the magnetic shocks to see if they are what you’re looking for.
