Tom.

I apologize for my ignorance here, but in your comment with the top picture you say “I position mine to rotate in the direction of the wheel.” Are we looking at the driver side or passenger side in the picture? I installed the fx system, and I want to make sure I have everything pointing and going the right direction. Just for the record my guess is passenger, and I’m betting red at the casino later.

Thank you,

Dave

Dave,

Now you are getting way too technical for us. Actually the only reason to even think about re-orienting the valve stems is so the sensors for a TPMS can be screwed on the steer and tag wheels.

Which way the valve stems point relative to the tire rotation is a question that can only be resolved with extensive testing to determine if fuel consumption changes, and if it does, will the valve stem orientation have to be a certain way for the best mileage.

Yes Dave, that was the passenger side.

Jon can send you the technical date, it’s stored on his flip phone.
