slow leak in tire

[Aernan]

My driver side rear tire leaks down slowly (2 days to go flat). This is a new problem it didn't do it for the first month or so.

I tried the soapy water trick and found the union between the valve stem and the CTIS kneeling valve was leaking. Looking at the TM it shows an o-ring there so I ordered and installed one. Retest with soapy water and I see no bubbles. After repair it's still going flat after a few days.

I looked at the whole sidewall and large portions of the tread for a puncture but have not found one.

Here are the things I think it may still be.
0. actual hole in the tire
1. rim seal to tire
2. rim seal internal
3. valve stem to rim
4. valve step to kneeling valve - still a problem but slow leak?
5. kneeling to ctis hose - I did disconnect it there and did not replace the seal.
6. CTIS valve itself
7. shrader valve on body of CTIS valve - has cap so I doubt it.

Any ideas?

Run over the tread with soapy water, if good, likely the rim o ring.

Take off banjo bolt. Put plastic bag scrunched down over banjo assembly and rubber band down over hose tight. If air is leaking thru the valve the bag will expand.

That's genius. I will certainly give that a shot.

Do I need fresh washers/seals when I put the bolt back in?

 

[Suprman]

No the old one should still be ok. They all leak slightly.

When I put the o-ring on I put it over the valve stem. Looking at the TM I can't tell if it goes inside the squat valve effectively at the end of the valve stem. I think I will remove it again and see if it's even possible to install that way and also clean the squat valve.

I hate those kneeling valves I remove them usually.

Not much of an issue if your CTIS works.

Tried open close squat valvevalve. After closing it took a while for the air to stop. I'm assuming it's dirty or tired spring. Didn't have time for tare down tonight.

not sure but might not be speaking just for myself..... but really hope soon you figure out how to upload to this board instead for posting pics thru tapatalk. Some great info you have posted is going to end up useless for others right when they could really use it cause changes to Tapatalk or your account there, will assuredly happen, making all you pics disappear in here.

PS... it looks like if you can just upload/attach using the links you have been using inside your post. Just in a post your writing click the icon that looks like photo album image of a tree.... click on [From URL] ... cut paste in your URL and whala....... pic uploads to here. Used one of your URL's to do below attach

I can't upload from desktop unless the image is at a URL already. I could setup photobucket or something. Is there any way to direct upload?

So it looks like someone used that valve as a step. I bent it back. Next day tire had more air but still low. Chances are good it's a leaky valve.

 

[Suprman]

Eliminate that thing.

???????????? totally confused..... your photo's show up here on the board as a URL...... So do whatever your doing then after posting .... edit the post and use the URL that taptalk supplied to upload/attach properly into the post. This is exactly what I did.. used the url found inside your own post to upload the picture)

otherwise as suprman says (though he was refering to something else) get rid of that thing (Taptalk)

My Ipad seems to work fairly well by starting at the SS website and going to manage pictures, then taking one and downloading it. So far I've just done pictures and have had a hard time getting at the "done" button, but it usually works.

To recap. I can upload from tapatalk just fine and I guess after upload I could edit by importing from URL that tapatalk posts the photo to. Is there any way to just directly upload from my laptop? I found the button but the confirm after picking photo never appears.

you can:
. scroll down below the post area and on bottom right corner click box [Go Advanced]
. scroll down below it's post area and click on left side [Manage Attachments]
. This will take you to a more formal version of adding pics from a url or from your hard drive.

Thanks for the explanation. I've never viewed from anything but tapatalk. Didn't realize tapatalk linked photos instead of embedding them.

I replaced the guts of the CTIS valve last night.
