Inside dually extender won't indicate anything on pressure gauge.

I just had 6 new tires installed on our 2000 Fleetwood Pace Arrow which has 245/70/19.5 tires. When I got home, I was curious to see what the air pressure was and if it needed adjustment. The fronts were at 90 and the rear outside was also at 90, but I couldn't get any indication from the inner tire valve extenders - nothing. Has this happened to anyone else, or am I missing something?

Hi DMS110,
Welcome to iRV2. Not much you can do except:
1. take it back and have the tire dealer fix the problem
2. get your old clothes on and figure out how to make sure the extender(s) are tight on the valve stem

Wrong ext. or insides are flat. The ext. must have a rod to depress the valve or the valve must be removed from the stem on the rim.
Take it back to the dealer.

Yup, this happened to me. I wasn't getting a reading so I attempted to change out the valve stem and wondered why no air escaped as I was unscrewing it. It turned out that the inside dual was completely flat with a hole about the size of a quarter in the sidewall. Just giving it a cursory look, I couldn't tell.

That was a long time ago and now it would be the first thing I would check if I didn't get a reading from the gauge.


eta: I didn't catch that it is on both sides this is happening, right? Then it obviously isn't a flat on both sides. Can you unscrew the extender and take a reading or can you get to the valve that way? Seems like both extenders can't be bad, though.

Well, I just went outside and tried again, after taking the $5 Slime tire pressure gauge apart and not finding anything wrong with it. I had to hold the extender with one hand and push really hard on the tire gauge with the other - presto, it worked on both rear inside tires. I had read other posts about inside tires being flat and hoped they weren't after just having the tire place mount and install them. Thanks for your replies!
