Extension tire Valve problem on

[Tncatfanforever]

On my 2018 Georgetown I cant get inside tire valve extension to take air. I can take pressure with gauge so it flows out but will not accept air. Am I doing something wrong?

The extension may be loose.

Can I tighten it without removing the tire

The mechanic did it on my Forester. You have to reach in between the tires. I would just take it to a garage that does motorhomes.

[Hi Rider]

I also am interested in any responses to your issue. Every valve extension on my 2016 Forester 2401W MBS ultimately failed. The extensions would not respond to gauges when checking air pressure. Some would not take air. All now removed and that is after a flat that ruined a tire at 15,000 miles and a second flat at 24000 miles that also ruined a tire. Just put on six new tires and adding a TPMS system.

If you have any plastic extensions, throw them away.Steel valve stems and extensions are recommended for TPMS. Check out https://www.shinyrv.com/
