Trailer TPS Sensor Question Rim Size

bruceb58 · May 10

Buying a new trailer that has 16" rims vs my old trailer that has 14" rims. My understanding is that the 14" rims have a 0.453" valve stem hole and the new trailer 16" rims will have 0.625" size valve stem hole.

What do I need to do to transfer the TPMS sensors to the new rims?

You start with finding out what size tire valve the new rims actually uses, instead of guessing/assuming/using some ai bot to tell you.

Then, if they truly do use a different size, you drive out to the nearest lake with at least 10 square miles of surface area, throw all those TPMS sensors as far as you can into that lake, then drive back to town, buy new tpms sensors that fit those 16" rims.

Wow...thanks for the help! Just getting prepared!

Hope you have a better day...maybe tell someone's mother Happy Mother's Day!

I did find the solution.

Need to buy these to adapt.

Thanks for the info but wow, these are pricey! $100 apiece. A full set of smaller ones can be had for less that the cost of one of these. Gotta be a cheaper option out there but I have yet to find it. I don't want to use grommets as I can see leaking in my future.

Now that I am looking at it, I might be able to just get the valve stem and modify the sensor to fit. Looks like I can just modify the hole a bit to adapt.
