TPMS leak - Service kit

[CHILLIBAJJI]

I got Tsportline 18" wheels and Costco mounted Xice snow winter tires. I did get TPMS's from a fellow member here.
One tire is leaking - about 4-5 PSI overnight. Costco is saying it's a TPMS problem not a tire problem. They say TPMS is leaking and needs a "Service pack".
He is saying taking to dealer.. but I don't know if Tesla Service center will do anything to Tsportline wheels and Costco tires... and member bought TPMS.. they might blame any or all of it..

Do you guys have any recommendation?

will this work?

Tesla TPMS Service Kit

This TPMS service kit for your Tesla Tire Pressure Monitoring Sensor includes new hardware, a seal, a cap and a needle valve. Each kit has enough for one sensor. These high quality components are made in France. Fits Gen 1 and Gen 2 TPMS sensors in the Model S, X and 3.

or just buy a new TPMS and have Costco replace it?

No reason to go to the dealer, a service kit should work just fine. Tire Rack can also sell you one for the Bluetooth Tesla sensors, (Will be "Dill" branded) but it's not listed on their public website. (The link you provided doesn't look like it's for the new BT sensors - do not buy that one! It omits Model Y compatibility, because all Model Ys are Bluetooth)

Did you ask where the leak is coming from? If it's the valve core, any valve core should work. If it's the rubber TPMS gasket inside the wheel, it was probably installed wrong and possibly damaged if it's brand new and leaking. No reason for a leak on new wheels and new TPMS sensors...

Thank you.

I got these .. but they are $24 each.... Black Valve Stem - Fits OEM Bluetooth Tesla TPMS

I have a feeling that it was installed wrong. but there is nothing I can prove. Costco kept saying, nothing wrong with tire... and it's leaking 5 psi a day. pnly one tire out of 4.

Yikes, $24 is steep, but definitely what you needed. I think Tire Rack was well under $10 for each. Small price to pay either way.

 

[CHILLIBAJJI]

yeah.. need to be safe.. and don't want to try diff things.

You probably just need a valve core. Not a big deal. Spray some soapy liquid on it and see if it bubbles. You can just unscrew them and put a new one in.

Why didn't you get the whole package from the TSportline?

 

[CHILLIBAJJI]

the wheels were on sale for 1000... not the package. the combination I wanted, 18" with X-ICE wasn't on sale..
