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.

Have a 2024 Yukon Denali XL, no air suspension and the option 22 inch wheels with 275/60R22 tires. Overall I think think it rides very well. As mentioned I think the magnetic ride control seems offer a good ride. I have not compared my vehicle to something with smaller wheels, but I will way the vehicle ane seats are up much higher than my 2005 Yukon Denali XL, so it is easier to enter and exit the vehicle using the running boards, never use them on my 2005.

So depending on how tall your wife is, you should try getting in and out of a number vehicls with different tire/wheel combinations, fixed vs retractable running boards and with and without air suspension. I beleive the air suspension can lower for entry and exit, I just do not know if this can be configured automaticaly and how quickly the air suspension can deflate and inflate.

Yes, it can lower; and yes, you can configure it to lower or not. It takes @ 5-10 seconds to lower completely.

If you truly want the plushest ride known to man, look at a 2017 to 2019 Buick Lacrosse. We test drove one a few months back and it was the nicest riding car I've ever been in! It's a shame GM killed it. You can find them relatively affordable with lower miles still. If I wasn't so stingy, I'd run out and drop 20k on one with less than 30k miles and have tons of smiles per mile on road trips. The trunk is huge as well.

Aspect 'ratio' is not as important, as how much sidewall beef between the contact patch and the wheel.
275/60R20 (33.00" tall) has 6.5" of sidewall.
Both 255/75R18 (33.06" tall) and 275/70R18 (33.16" tall) have 7.5" of sidewall.

More sidewall, protecting lighter wheels, less unsprung weight too.
Whatever gave you the cockamamie idea that that'd jeopardize the warranty?
You'd improve the vehicle's longevity / durability - the steering and suspension will thank you, even the MagnaRide,
to give up things you both want to give up anyway.

Try to pick the lightest 18" wheels for best results.

Not all of them come with that tire size. These trucks were made for towing and I find that they ride best with a load on. Put 50-75 pounds in the back and she'll settle down. A full tank of fuel weighs about 156 pounds.
