Valve stem size for F14's

gomer_110 · 01-26-2019, 09:40 AM

Does anyone know what the proper bolton valve stem size is for the Forgestar F14 wheels? I always assumed this was something that was standardized on a single size but I guess not.

I'd just measure the wheel myself but I can't find anything that's clear on if it's the through hole or the boss around it that the measurement refers to.

Thanks in advance.

Some steel aftermarket valve stems will come with 2 different sizes of rubber grommets. You needing the larger size? Check with either NAPA or Advanced Auto.

The the diameters are 11mm, 15mm, and 19.2mm. The 19.2 is for truck type rims.

Fairly sure you’ve done some research, but this could be a good reference for others. https://tirerack.com/tires/tiretech/...sp?techid=208&

I recently bought this for a set of OEM Infiniti wheels, comes with 2 grommets.

The ones from Amazon is the same ones I got from Advanced Auto for my PowerWagon.

Small hole, a (.453) standard rubber valve stem will pull in.
The holes on my F14 19x12’s are a tad over (.410) & I’ve pulled the small ones in with no problems.....testing purposes

jchammond · 01-27-2019, 03:08 AM

These are the new ones that came in my F14’s...the rubber piece that inserts in hole is about (.425)

What is the question?

A. What size non-tpms valve stem fits?

B. What size rubber grommet goes on the TPMS?

Question was when I go on a site like summitracing.com which bolt on valve stems do I need to order to fit the wheels? I always thought there were only two sizes; one for passenger vehicles and one for off road equipment like farm tractors. I was clearly mistaken with all the different size options I saw.

TPMS had nothing to do with the question.

I've been trying to find out the same thing (also have F14s). I want the 326power Valve Stem Caps and they told me they should fit without any issues. Guess I'll order and find out.

All caps are the same size. It's where the valve goes through the rim that is in different sizes.

For the benefit of others, these are the ones I ordered:
Gorilla Outer Mount Valve Stems

Just installed them and they seemed to fit just right. Getting the tires mounted tomorrow so I'll see then if they truly were the right ones.

Are the replacement TPMS seals 0.425?
