What's your RLX tire air pressure?
What's your RLX tire air pressure at?
I set mine at 36F/34R but it feel bumpy(not too comfortable) but MPG is not bad.
Have anyone tried 32- or different setting that make the ride more comfortable?

Most of you are likely aware of this, but it is something to consider - The cold tire pressure that you inflate your tires to is not always the tire pressure you are driving on as tire air pressure can fluctuate during different driving scenarios. For example, a long highway trip will heat up the tires enough that the tire air pressure may increase by at least 2 - 4 PSI. Conversely, if you live up in the frozen north as I do, leaving your nice warm garage and driving your car in 30 degree below zero temperatures will cause a drop in tire pressure of at least 4 or 5 PSI.
Just another factor to consider if you find the tires too firm or too soft, so check your TPMS numbers on the MID in the middle of your driving trip to see where you are really at.

Put what the door jam sticker says at cold temp.....yall have them too high and causing bumpy ride....

It is just the opposite of what you said......more air = bumpy stiff ride....less air... smooth....The door jam # is recommended for maximum comfort.. if you cram 5 heavy adults and luggage that may warrant more air but remember when those tires warm up and PSI increases as well and well we are back where we started.....OVER INFLATED TIRES!!!!

How 'bout lets level the playing field and understand which are tires size everyone is using...18's or 19's...that will reflect different inflation pressures.
When you inflate your tires, are you using a hand gauge or are you using the MID TPMS to set your pressure?
If you don't use the TPMS during the tire servicing, you'll never be able to accurately know what your pressures are unless you stop and check them. By using the TPMS to service the tires, you can see the different fluctuations on the fly...

i went to the dealership on thursday to find out why the car ride is so bumpy. i tried different air pressures and the ride really hasn't gotten much better. i know what it say's on the door sticker i have even tried that. I ended up putting nitrofill from the dealership and i have to admit the ride has gotten somewhat better. The only thing i dont understand would be the dealer putting the air presssure at 32 all around when the door sticker states otherwise.

But the real problem is that the suspension/bushing calibration is not very good. You can move psi all over the "normal" range but it is still not luxury in its ride. I got out of the RLX and went home in my Advance MDX and the ride was much better in the MDX.

Nothing yet I driven from Acura rides as well as my 2007 Acura MDX Sport........nuff said.....Oh and the larger the tires.....the harsher the ride.....NOT too many bought the 19" low profile tires for the 2007 MDX that was an upgrade option due to this exact reason.....RUFF RIDE......BIGGER TIRES ARE NOT ALWAYS BETTER.....

As I was catching up on my reading last night, I noticed that with 19" wheels the manual called for a very Old School setting of 35/33.
I guess they're afraid that a change in a PAWS setting will introduce some oversteer.
Of course, the car was delivered with 32 all the way around.
I'll change to 35/33 today and see what difference it makes.

The door jam states 36/36 for the SH.

Great info. My brand new SH came with 38 all around, but there was slightly more in the fronts- they got to 40 in front and 39 in rear after driving. I just lowered them to the 36 all around stated on the door. We'll see if it improves the ride

Ive tried all sorts of tire pressure settings over the past two years in an effort to subdue some of the effects of the faulty suspension design in the 2014 PAWS.
what Ive finally settled to is a 33F/32R cold. This usually ends up maxing out at a 37F/35R or 38F/36R (depending on cold or hot westher) once the tires heat up and the steering feel / suspension for me is at its optimal response at these pressure settings. The driving mechanics and steering feel have a laser accurate confidence yet comfortable, and the energy transfer to the chassis from bad road conditions is slightly subdued.
It's the best I can get until I get rid of this thing :|

My comments from 2013, I was driving an RLX P-AWS FWD car.
With the Sport Hybrid that I got in October 2014, I went with 35 or 36 at all four corners.
That's what the manufacturer recommends, and I believe I understand it.
If the dealer moves it down without thinking about it, I'll put it back up there because there is a difference that even a stupid old man like me can notice.

Otherwise, you run the risk in some maneuvers of radically increasing the front tyre patches, which means snap oversteer in a car that would usually understeer.
With the weight of the batteries and the two electric motors in the rear of the Sport Hybrid, it's a different matter.
Now...if you want to induce oversteer, and you're prepared for it, then, sure, run lower than recommended pressures on the nose of a P-AWS car. The electronics might catch it most of the time, but if you turn off the safety electronics, it can be fun. :-)
There's a video around here somewhere of Jeff Palmer in 2013, taking a P-AWS RLX through an autocross course and trying to show us how it's better than a 5 Series BMW.
It might be fun to dig that up again.

The P-AWS car has a different weight distribution. You want heavier air pressure on the nose to lessen the effects of weight transfer on the front tyre patches.

I think that I know what you mean.
If the dealer moves the pressure down, then to me the Sport Hybrid seems to wallow when I'm driving along. The sidewalls are too squishy for the weight of the car, and the rear end isn't doing it's job in a corner.
So it's pretty obvious when I pick up the car that the pressures are wrong, and I just fix it when I get home. The next time I go in, I'll mention to them not to change the pressures. :-)

Interestingly enough, I just picked up my PAWS from the service center after an oil change including tire rotation/balance and an alignment that I requested (steering was starting to pull to the right). They set my cold tire pressure to 33F/33R and dare I say it almost felt like I was driving the SH! The tires finally settled to a 37F/36R after driving a bit and things just felt more compliant. Hitting bumps etc seemed to transfer far less energy to the chassis creating a much more confident driving experience. The symmetry in the steering feel and forward movement of the car also felt sooo much tighter. I know the alignment had a play in this as the before/after readings they provided me on camber/toe/etc showed the front-end was off by a good bit. But I have to wonder if the 2014 PAWS using the same suspension as the SH works better in terms of dealing with less than perfect road conditions when using the same PSI distribution as the SH (same PSI across all 4 tires). Even if this does effect things like over/understeering, I dont really drive my RLX that hard where those conditions come up often. So I'm willing to sacrafice that easily for a more compliant and confident driving experience similar to the SH.
I am very sensitive to tire pressure settings and can instantly tell when things are off and how it effects the steering and handling.

I can drive people crazy with sensitive. :-)
About being able to "feel" VCM:
George: "Okay, we're on three cylinders."
Service: "You can feel that?"
George: "Yes. Can't you?"
Service: "Well, no, not really, but the computer says you're right."
About the DCT 7 roughness at moderate acceleration:
George: "Okay, see, it's having trouble there."
Service: "You can feel that?"
George: "Well, sure, can't you?
Service: "Not really, sir...."
LOL....

Ha! I've felt the same way in similar scenarios. The A/C moan issue was one of those.
I just came back from a weekend road-trip down to Moultrie, GA and I am almost 100% convinced that the Default OEM PSI settings recommended by Acura on the 2014-2015 RLX with the front / rear offset of (2) PSI (35F/33R) was a bad call. I need to drive the car some more this week around town through some areas I know very well where the suspension really gets worked before I make any final calls, but I'm pretty close to saying that my 2014 PAWS feels like a very different car now with these new PSI settings (and the alignment) in place, whereby I am using the same PSI across all 4 tires instead of the offset. In addition to this, with the reduced overall weight of the PAWS versus the SH, I think the setting of 33 versus 36 helps offset the reduced weight of the PAWS, resulting in a similar weight / tire pressure ratio of the SH. Thus the end result: the suspension in the PAWS behaving much more like the SH.
I want to make sure there is no placebo effect going on here, so I'll report back later this week. But I'll end in saying that my road-trip this weekend was the first time I really enjoyed driving my RLX in a very long time...

Should I drop to 28 psi running 17" snow tires from the stock 19"s at 36 psi?
From discount tire: "Another valuable resource is tire load/inflation tables. Your local Discount Tire should have a copy. Not only will this document tell you the correct tire pressure for stock sizes, but it will provide the information on optional plus sizes as well. A good example would be the findings on a Honda Civic with the stock size 185/65R-14. The recommended air pressure is 28 psi. Plus one size is 195/55R-15 with a recommended air pressure of 32 psi. Plus two size is 205/45R-16 with a recommended air pressure of 36 psi. Note how the air pressure increases with plus sizing to meet the load carrying capacity for the car"
