Trouble airing back up? TPMS info inside!

[JAYB1RD]

On my first trip offroad with the H3 I had a problem bringing the tires back up to the proper pressure for the drive home. It's because the TPMS valve stem is so short, that the average gas station that has the angled air chuck can't fully seat onto the valve. So there I was, stuck in the middle of Michigan with only 20psi in my tires and no way to pump them back up! Fortunately for me, the gas station down the road amazingly had one of the straight air chucks, and I was able to fill the tires. Once I got home though, I put a couple valve stem extensions in my grab bag of parts that rides in the back of the H3 on trips like that. My friend who was with me at the time has since come up with an even better solution.

Longer valve stems is his idea. GM p/n 15136883 or 15114379 will work with the H3s TPMS system, but the stem is about 1/4" longer so the angled air chuck can be used. Each of those numbers is the same part, but his system has two different prices listed for them. So get a quote on both before you buy. GMpartsdirect.com has them both listed at $30.50, which is where I will order mine from soon.

p/n 15122618 is the stock valve, just FYI.

Enjoy! Feel free to ask any questions.
