Toyota Tundra Forum

Hello All,I have a 2005 Toyota Tundra regular cab 4x2. I checked the tire pressure the other day on the truck and drove the truck to work and when I left I found one of my tires flat. Needless to say, I discovered that the tire had a slow leak from the valve stem probably caused by checking it with a gage or filling it from the air chuck. Eventually the valve seated and no longer leaked. The question(s). Can the valve stem be repaired/replaced without removing the tire from the wheel? Is this common with this type of system? In the old days you could remove the valve stem. Can these be removed and perhaps tightened? I appreciate any info on this as I am monitoring my dash pressure indicator and hoping it stays off. I also understand that this light can come on if the spare is low as well. Thanks !

If it was leaking from the core like the one below try having it replaced.
It may have just had some dirt in it.

Yes...the schrader valve is leaking and it doesn't always fully seat after checking tire pressure with a gage or filling with air from an air chuck. I was wondering if they had the same innards as a regular schrader valve. They used to have the valve cap that had a side with 2 slots used for inserting into the valve body that you could tighten or remove the guts. I am wondering if the valves on TPMS sensors have the same configuration? Thanks again.

TPMS stems are the same mainly they are nickle/chrome plated instead of brass ,use caution when reinstalling as they must be torqued to 4-6 inch pounds. Any more torque and you risk stripping out the stem $$$.
