I recently purchased a 2016 CVO limited. It comes standard with T.P.M.S. and my dealer put Nitrogen in the tires.

Last week, I got a low tire pressure warning, and checked the values. Rear was at 24lbs. Rode it home, and as expected while the tires heated up, the pressure came back to normal (Note: it was  cold night for Texas).

Day before yesterday, the alert came back on and stayed on. Pressure in the tires was at the recommended values, however it said that they pressure was low. So I dropped the bike off at the dealer and after purging the tires completely and reinflating with air the alert went away.

The tech called the motor company and was informed that Nitrogen is NOT recommended with the T.P.M.S. system.

I did not agree with that and it is contrary to what every tire and T.P.M.S. manufacture says about Nitrogen.

Has anyone had a similar problem like this with T.P.M.S.?

Welcome to the board.  Another long time forum member lives in Tracy (although he hasn't been active on here lately).  Lot of forum members in the central valley and bay area.

If it's coming from the MoCo....probably a good idea to question it.  All the RV and trucking industry use TPMS and a lot of them use Nitrogen and I haven't read anything on the RV forums about it being an issue.  I didn't have any problems in my 5th wheel.  I'm calling BS on this one.

The tire pressure reading is when your tires are cold.  So if it started out at 24 psi either the tire pressure was low or the TPMS (like all the Harley gauges) is just not that accurate nor reliable.

Are you taking your bike to Eagles Nest or Livermore?

Yes Mom, I still believe in Santa Claus.  Harley-Davidson said so.

JCZ is correct.  Someone is feeding you manuer. 

Sorry but you air contains many gases like nitrogen, oxygen, carbon dioxide and argon among many others.  Nitrogen is by far the largest component of the air.  (78% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide)  It is inert and has no effect on your tire pressure other than to keep it SLIGHTY more consistent.  Your tire pressure will change 1 or 2 psi for 10 degrees of temperature change.  24 psi in the rear is not safe.  Whatever was the cause, it was not nitrogen.

The guys are right, I have run nitrogen in my pickup truck for years with TPMS and no issues.  Someone at the dealer as usual is full of it.

Oh welcome to the site.

And now we have even more proof that dealership "technicians" are not only stupid but also think everyone else is as well.  Not that we really needed any more proof of course.

If the tire pressure monitoring system was still giving you a low reading even though a real gauge said otherwise, the fault lies strictly with the Harley system and has absolutely nothing to do with the makeup of the gases used to inflate the tire.  As noted by Greg, regular old atmospheric air contains about 78% nitrogen, and if that "technician" was aware of that fact he would know better than to blame the problem on nitrogen.  Must have dropped out of school before taking any science courses.

Btw, it sounds like the system sensor didn't reset automatically like it should have when the tire was re-inflated the first time.  I'd keep an eye on it by comparing readings from an accurate gauge to what the system says for awhile, and even try adding and removing air to make sure the sensor tracks right along with your higher and lower real pressures.

I've got three  relatively new vehicles and the big deal the Dealer does is fill them with Nitrogen because it reduces the affect the temperature has and maintains the pressure more consistently.  These vehicles have TPMS, no issues.  Your prob might be with the TPMS system.

Thanks for the info and apologize for the mix-up.

I was born and raised in Stockton.....so were a couple other members on this forum.  Being raised there, you know why we all leave there. 

So tell me......in the summer months is it hotter in Stockton or Texas?   Just one more reason we all leave Stockton.

Yes, I do. I have been back over the years to visit friends and family. I am very disappointed with what my home town has turned into.

My Grandfather was the recipient of a Homestead plot years ago. He sold part of it to make the Elkhorn Golf Course, and kept 40 acres. He gave my Dad, 1 acre, and after my Grandfather died, my Grandmother lived there until it became unmanageable for her, sold it, and for years it remained that way.

Now I go out on Davis Road heading toward Lodi, and look to my right and see this HUGE Brick wall between the Acre my Dad had and a giant subdivision beyond the wall.

Dad way undersold his place, and some Bay Area doctor dumped a ton of money in it and tripled the size. Looks great but takes the memories away.

I know off topic.

It seems the more technology HD adds, the more issues we encounter.

What brand of nitrogen did they use?  Perhaps they only work with Harley brand air or nitrogen?

[solutionsville]

Cat Eye, they use a machine to convert the AIR in the tires to Nitrogen. Purge the tires and then put back in the correct PSI.
