Assuming that your right between those two sizes, it's 8.3

I just bought two from Triumph for my '11 Roadster to use on my next tire change. IMG_3491.JPG IMG_3490.JPG

There's a "shoulder" just before the O ring that is slightly wider than the threads.
 
The T-valve stem on the FOBO website says they will fit 8.3 - 11.3 mm holes. It looks like they have a cone shaped plug allowing them to fit most rims so I expect they would fit the rocket rims.
I bought these. The T does not physically fit on the Roadster wheel because of the rim design. It will fit in the hole but not the rim.

Dang, that is too bad. I have a touring. Does anyone know if the same issue will be experienced on the Touring rims causing not enough clearance for the T-stem and the TPMS mounted on it?

Sorry, just the rear wheel doesn’t work. The front works great and is very convenient.
