You are in the Acura MDX
What is this discussion about?
Acura MDX, SUV

I have just spoken to an Acura technician who told me that adding a few pounds of air pressure does NOT stiffen the suspension, but rather makes you "think" it has because it will ride a little rougher. Riding rougher will actually make the suspension work harder as it will have more vibrations to filter out.
That "well-known old procedure" is a myth.
Check with Acura yourself.

Don't know why a knowleable mechanic will say the latter, if it is well known that when you provide more feedback to the shock's valve system, it will act as if you are going faster, and which shocks are tuned to become stiffer as the vehicle speed increases.. The more road feedback the stiffer the shocks become.. Again we are not talking about large psi increases, so you are not really increasing vibrations but lower frequency feedback to the shocks valving system, or in the case of the ADS, increase feedback to the sensors that gives input to the ADS system.
Shocks don't have a constant damp by design. If you are familiar with shocks, you will find that weak shocks or shocks with weak damping capabilities will make the car wobble, which is the usual problem with worned shocks or shocks with variable settings.
When you increase your damping factor, you will reduce your wobbling on uneven roads..
Even for towing purposes, you increase your psi to avoid overheating your tires (flexing issue) and to increase the damping capabilities of your shocks and to have more control during towing..
I am not telling this only from past experience. I am mentioning this because I like my MDX firmer when I am in the highway at around 70 mph, and it becomes very obvious how the handling changes when you put 36 psi vs. 32 psi. Just a couple of psi in your tires make a big difference..
It is not my intention to contradict anybody, I am just posting what I, and many people, do to improve handling or to improve driving conditions..

Thanks for the info. I am going to check into this a little more as this is very interesting information. Today I checked the tire pressure info on the dashboard and it read 35 lbs. for each tire. I just had service done at the dealer a couple weeks ago and that is what they put in.
We have to remember, though, that as we increase speed, the heat from the tire increases the air pressure. How much I don't know as I've never checked the pressure at different speeds. Might be interesting.
On most roads, I can't tell the difference between the Sport and Comfort settings, or at most a very small difference. But my MDX only has about 7600 miles on it. As time goes on, I suspect that I will eventually notice more of a difference.

I also own a 08 RL & 11 MDX. Both are excellent riding and no problems as of today. The mdx has more bells and whistles but both vehicles are better than my former 2007 Lexus RL. Espcially with the rear and side visibility. We have own nothing but toyotas or Acuras. In today's world I'll again buy an acura if I live another 7 years.
Good luck to all and stay safe.

Hi Cloviskid. I agree with you as I also purchased the Advance system and my wife and I drove 7500 miles from Ca, across country, through Zion, and over the badlands and the Acura did a wonderful job making our trip pleasurable. My wife retired this year, (Im 69) and we are driving again across the country and visit wit our son and his family in Rockford Illinois and then tour up north coming home. This is the best Acura I have owned and I intend to keep both of our vehicles for a long time.
Good luck to all and stay safe.

"..Check with Acura yourself..."
And encounter yet another IDIOT like you did...no thanks.
"..Does not stiffen the suspension.."
Correct, it only "stiffens" the tire sidewall. And yes, with a a higher tire inflation level, "stiffened sidewall" the MDX will ride a little rougher.
"..suspension work harder.."
Isn't that the point..?
