2019 3500 Tradesman duel Rears tire pressure

[Wadejesu]

How in the hell do you check/change tire pressure on the rear? Both valves with extensions are on the inside and face each other , what a pain.

I’d take it back to the dealer and tell them to “index” the wheels. They should know what that means but guessing they won’t. The valve stems on dual wheels should be in opposing positions. They need to rotate the outside dual to place the stems opposite of each other.

Get one of these.

You need dual foot gauges and chucks.

I think I have solved the problem,

Honestly on my dually, I had the extensions on the inner rears for a year or two. Found I never added air anyway. Was worried the extensions were going to cause a failure, so I removed them. Again havent added air for two years. Once every couple of years I remove the tires for a good cleaning, and add air if needed.

Steven, Funny you mentioned that because that's exactly what I did, Thru away the cheap plastic extensions and put real caps on the stems. If I ever replace tires I'll replace TPMS with Metal stems.

The factory extensions are perfectly safe for long-term use. They are designed so that the center pin in the Schrader valve is only depressed when you are adding or releasing air. The rest of the time the air seal is maintained inside the valve, exactly as if a little rubber cap was screwed on in place of the extension. I've been using these valve extensions for 50 years. Never had a problem.
