General TPMS sensor question
 

I recently bought a set of wheels and tires (off a 2013 Jeep Wrangler Unlimited) for my 08 Grand Cherokeefor a good price. I feel like I got a good deal because the TPMS sensors were removed. Is there a way I can tell, visually, if the TPMS sensors are still installed?

No most newer vehicles tpms comes with rubber valve stems. Althought the tpms valve stem does look a little different, there is no way to know for sure without looking inside.

The newer rubber stem tire pressure sensors can be easily identified by the 1/4" of non-threaded brass shoulder leading into the rubber sleeve.

No you can't tell unless you pop the bead on the tires. All the newer cars some with the rubber type tpms sensors but you can't see the sensor bolted to the stem in the tire with out removal sorry

Read my post above you. They can be visually identified from the exterior.

Just because it has a tpms valve stem does not mean the sensor itself is still attached. Only way to know without breaking down the tire to see, is a tpms scan tool.

Although highly unlikely, that is possible.

Not really. If your already putting new wheels and tires on your brand new vehicle why waste a few hundred $$$ on perfectly reusable parts.

In my 10+ years at a very high volume tire shop, I have never installed new wheels, tires and all new tpms on a new vehicle.

You're contradicting yourself here!

If you want to reuse good parts, you would most likely reuse the stem along with the sensor, and put a standard stem in the wheels you're selling.

No I'm not. Snap in (pull through) valve stems can not be reused. Plus they cost $1, average cost of a tpms sensor is $85 - $100.
