Tire pressure on RG3 ?
What tire pressure are you all running on the new RG3 trike with the new low profile tires on it? How does it affect the TPMS on the trike?
I was looking at one the dealer had and it had 38 in the front and 28 in the rears. On the Freewheeler I have been running 36 in the front and 22 in the rears it came with 26 in the rears but lowering them to 22 improved the ride. Just wondering how its working on the new RG3.
I don't have a RG3 - have an Ultra that I converted to a trike by adding a CSC kit. I am running 38 in the front and 24 in the rear.Originally Posted by Kneesinbreeze
No effect on the TPMS
They are essentually the same machine, so if you were happy with the 36/22 on the Free, I'd say go the same on the new ride. Let us know what you think on the new RG3 air pressure change.

If the HD TPMS is like most automotive ones the light should not trigger until the tires read 25% or more lower than what the placard affixed to the bike calls for
(or what the owners manual states)
I would not hesitate to lower the front and rear

My CVO with the low profile tires I run 36 front and 22 rear, the low pressure light is on all the time and usually the notice will pop up on the screen asking if you want directions to the nearest service station, just hit NO and carry on.

Curious -which tires are registering as low? Have you reset the codes to see if the light goes away?
I was riding one day and my front showed 40. So, I let some of the air out. Soon after, the light came on - so, I out a little more air in. Light would still come on every now and then. So, I reset the codes on the bike.
Resetting worked for a short time - but I got the light again. After some research, I pulled the main fuse for a few minutes and let the bike computer completely reset itself. Since then, I have not had any problems.
Pulling a main fuse or disconnecting a battery will only give a temporary reset of modules and an ECM, codes ( particularly historic codes that have not been repaired and then cleared) will surely come back
There are many folks reporting this all over the net, at best this is a band aid on a broken leg

I respect your opinion Sir - however this is not the results that I was able to obtain.
I properly aired the tire - checked with a manual gauge, cleared the code and then pulled the main.
Perhaps the poster would consider my response and see what results he gets. I am careful about posting any sorts of technical suggestions unless I have used them and found success.
I agree your problem has NOT reared its ugly head again but it will
Pulling the main fuse does not clear codes period, ( the code is in the background) if a good scanner was available it could check right away for pending codes, that will be where the code is hiding) it is like control alt delete on your computer, it clears a problem temporarily, the fault is still there lurking until you correct the fault and properly clear the historic code
Do not be fooled by internet chatter, it is bad JUJU

While you may be correct Sir - as mentioned, I believe I cleared the fault by properly inflating the tire. To verify the inflation, I used the gauge to be sure the tire pressure was correct.
I then used the bike's system to clear the code but noticed the light was still on. It was then that I pulled the main to let the system reset.
Maybe it will come back - I did this in mid-July and when I out the bike away in late October, all was fine. I plan to hopefully uncover the bike sometime in April -and will happily let you know if the light comes back on.
Still, I think for the OP, it may be worth a try.
I am correct and so are you, pulling the main fuse as you have done ,will clear codes, ( a soft delete) but when the BCM sees the code again ( and it will) the light will be back on

Your technical knowledge by far, exceeds mine. Still, I am curious as to if I properly inflated the tires to correct the matter, why then would the code come back on.
Having said that, if my tires become under inflated, I absolutely expect to see that code again. After all, isn't that the design.
My wife accidently left our trunk light on in early 2022 - killed the battery. When that happened, I got the low voltage code. I corrected that by turning the light off and charging the battery. I also cleared the code by using the bike's system/
That code has not reappeared. If I for some reason lose voltage, I do expect to see that code again too.
My guess is being a historic code may be a factor, did the code have an H?

Donald, it would be good to know from the MOCO what percent low will trigger the TPMS, I would also like to know what the voltage signal from the sensors is
The monitors go in sleep mode after a period of time to save the battery, so after sitting overnight they need to wake up to send data to the BCM, this could be a fly in the ointment IMO and could be a false negative, you may check this out on your next ride, check your pressures with a know n good gauge, then ride a few miles and report your findings.
I know of some systems that need what we call a roll off test to wake them up, it also wakes up the ABS systems ( you will note ( if you have traction control and ABS) the lights will flash until you are in gear and rolling

Yes Sir, it did. That is why I pulled the fuse
Don, it's always showing the rears are low, I don't bother to clear the codes as I know they will come right back. I'm good if I run 24 in the rears but liking the feel and ride of 21-22, I just ignore the light.

Historic codes are a real PITA, they depend on too many duty cycles to stay gone and reappear, this can drive a tech crazy
Your system seems to be working as designed, I do not like all this fancy stuff we are forced with, the old days were so much easier
When you get a TPMS light on, how low are your rear tires reading?

I have never gotten a light because of the rear tires; it was due to the front. I believe I mentioned this before - on a trip, I noticed my front was about 41 or so. Thinking that was a little high, I took some of the air out. As I continued the ride, it seemed that all was OK.
It was later that the front gave me the light. So, I aired it back up. That worked for a short time but then the light returned for the rest of the trip home.
After getting home, I again lowered the pressure and then again increased it to 37. Recalling, I normally start at 36 or 36 - then when on highway trips, the bike may get to 39 or 40.
My rear tires are set at 22. On the highway or longer trips, they usually get to 24. For my rear tires, since I have an Ultra that has a CSC conversion, my dealer installed two Harley TPMS sensors in the rear, and he set the sensors for me. I have never had a problem with the rear.
Gary - thanks. As I understand, no light at 24 but you do get as light at 22.
Curious - have you always run 22 and did you get a light during that time? As mentioned, my bike rears usually start at 22 - but they usually go up to 24 when travelling. I do not get as light when I start (other than the initial light when starting the bike).
Your dealer can adjust those setting for the TPMS. I know this because that's exactly what they did when they installed the two TPMS sensors on my trike.
While you are good at the light being on, I might still suggest that you try this. Clear the codes first, once cleared, pull the main fuse and wait about 5 minutes. Once you reinstall the fuse, you will have to ride the bike for a few minutes - it takes a little time to register the tire pressure.
If it works, great. If it doesn't, well, you lost about 10 minutes total. You decide what is best for you. When my trike was converted, I had that light on for about 5 months. Like many, I got to where I could ignore it - but hated it. My dealer said he could fix it but wanted to make it a winter project (this was the first time he had added TPMS to a converted trike.
I completely understood his reasoning. We agreed - they would try - but no promises. Now that mine is done and word has spread, he had done serval more. On top of that, CSC was notified that this was the fix - and now they can tell new (Harley) customers. that such is possible.
Good luck - it you try it, please let us know if it works.
