HELP – brand new 505a valve stem leaking!! – please advise

DC5 · 09-11-2005, 04:49 PM

Can the valve stem (of the air pressure sensor) be tightened only from the outside of the wheel or does the tire have to be dismounted and the valve stem tightened from both sides of the wheel?

I was polishing (mothers billit polish) my new wheels before bolting them on when I checked air pressure. Here it is: 28, 24, 16 and ZERO.

I aired all four to 30, and monitored for a few hours. One is really leaking fast and a little soapy water showed the valve stem (on one of the wheels) to be the culprit.

I really don’t want to have to ship this wheel back to John at CCW and wait another 1-2 weeks because I will not be a happy camper!

Just curious from you 505a owners: , did your tires have ~30psi when they arrived shipped?

Thanks.

I can tell you that on the new ( '01+) TPS the outside nut is it - there isn't anything on the "inside" of the wheel.. the TPS has a rubber grommet on the valve stem, which fits through the traditional hole in the rim. The outside nut then tightens and seals it. I once had a slow leak and simply needed to tighten the nut. However, you'll need to ascertain that there isn't some debris or some other reason why the grommet isn't seating, and sealing properly, if tightening the nut doesn't solve the problem. Good luck.

That's the Ticket!!
