Tire pressure sensors

I got my new wheels on, with TPMS sensors and the system works! I'll post something a bit more detailed in the How-To section.

Awesome. Gonna order sensors. Now I have to find a place to get them installed as my usual place has a policy of not installing customer provided equipment.

Is there an ability through OrBit to manually adjust/set the threshold pressure that you want the TPMS system to set a flag? or are these values fixed and non-adjustable?

Now I am not sure exactly how it plays, as I think the system isn't static like that. I'm new enough to it, I am not sure what the "calibrate" button does with sensor TPMS, I initially used it to make the car find the new sensors, but I also learned it will find the new sensors anyways. So it may be that you just "calibrate" exactly as you do the "indirect" system, after you set your tire pressures.

But there are settings exposed in OrBIt, 225-232 "TYRE PRESSURE..." for each axle, for all combinations of "load" and "speed"...now I don't know what those are used for, that happens with the config sometimes we know what is there but what exactly in the car is reading that and "configuring" itself for that field, we don't know.

understood, this is something I am willing to investigate a bit deeper after the "summer" wheels and  new TPMS sensors arrive. 

With my upcoming experiment ("AKA"  running CC tire sizes on a standard dynamic suspension optioned S60): I.E.= moving up to a 50 series aspect ratio tire from a 45 series. 
I am doing this to try and reduce the amount of "aggravated assault" being inflicted on the underside of the S60's bumper covers. will the handling suffer from this experiment?.. yeah, probably to some extent but for me since the S60 is being positioned as a DD vehicle (and not a WW track car) it is worth a bit of tradeoff to minimize the scraping (that sound is like fingernails on a chalk board to me.. drives me nuts). This isn't my 1st rodeo with this type of experiment, I did the same thing to my MKV jetta for the same reason with good results. 

some back history on why I'm asking about the threshold:
for my old MKV jetta there was an available toggle to swap multiple wheel/tire sets through Vag-Com. I also found the TPMS flag threshold was adjustable between stored wheel sets. (I am hoping this will be the case with the S60 as well) This came in handy when the 50 series tires went on the jetta. following the factory sticker in the door jamb at the 35psi setting, the jetta felt like it was wallowing through corners. I found the car handled better when the cold tire pressure was set to 41psi, so I bumped up the minimum threshold flag to 38psi on that wheel/tire set (IIRC the factory flag was set for 30psi. by setting a 38psi trigger point, the dash warning would illuminate before the wallowy feeling made it's presence known). 
I have a feeling that a bump in the S60's base tire pressure will also be necessary to keep the wallowy feeling corner's in check due to the taller sidewalls of the 50 series tires. If it is possible to bump the S60's minimum threshold flag value, this is something I would like to implement especially for my wife's consideration (she is a point "A" to point "B" type of driver and might not notice/recognize the change in handling characteristics as the tire pressure starts to drop like I would).

See what you find man! I think given when you have set the pressures, you then tap the "calibrate" button on the Sensus menu you are good. I don't beleive the system cares what you set the pressures too, it only monitors for loss of pressure, and perhaps there is an upper limit for warning of "over pressure". The indirect system certainly has no clue what the tires pressures are, it is only monitoring for changes. 

Where are you driving and what are you scraping on. Do you mean those parking blocks and curbs...I rely on the park assist to save me from those, sport chassis is sure to scrape on them ;-)

Probably has a sloped driveway. When I had a S60R with the factory sport kit with winglets, I quite definitely had to be VERY careful about what kind of inclines and driveways I drove up. Backing down was always a little easier as was taking them at a slight angle, but there was a lot of scraping going on.

I'm a little lost. Between this thread and the one on swedespeed
So, my car has the iTPMS. No value showed, just ok and not-ok
But I don't have keyless entey (unfortunately)
Could I just activate dTPMS and it will work? Or I need the new sensors as well?

No, I may be getting old with deteriorating eye sight, but I am still good at avoiding hitting parking blocks and curbs     and No - "drive it like you stole it" /dukes of hazard antics behind the wheel either, although there is some "off road" driving into several of the state parks which are unpaved, but so far (knock on wood) none of them have been as bad as getting in/out of the neighborhood.

It's the way the neighborhoods are designed here for water runoff, transitioning across or off the main roads at bisected intersections is a very slow and appropriate approach angles affair for anything other than lifted vehicles. hitting them straight on even at slow speeds...still a rude awakening. my wife and I both angle into/out of the driveway with the S60 as it is also a bit steep, but its moderate compared to some of the intersections we have to cross to get back to the house.

I'm still waiting on the "summer" wheels to arrive, TPMS sensors arrived late Friday (thanks again for the heads up Power6). once I get everything installed, I will see if I need to bump up the cold tire pressure to compensate for the increased sidewall height. If I do have to bump the pressure to minimize a wallowing effect, I will try the "calibrate" option and a couple of the existing TPMS settings options for the "low load" /"high load" to test the theory it will change the pressure that will throw a tire pressure warning flag on the dash before the wallowy effect becomes noticeable.

My understanding is that- If yours is a US domestic market vehicle with Sensus (other world market vehicles may be different) , it will have to have a full set (quant.=4) of new TPMS sensors installed in the wheels, then you can activate the TPMS pressure value setting with OrBit and see actual pressures instead of just the (green)ok/not ok(yellow) icons.

When I had a low car I was acutely aware of go/no go intersections, driveways, parking lot entrances, etc. It’s part of why its so hard to find a body kit fitted S60R with the winglets intact. They took away so much approach angle that they tended to get ripped off most cars eventually.
