5. Confirm maximum rim thickness at valve clamping area:
•
Is it 0.156” (4MM)?
•
[Normally not a problem with a 0.453” diameter valve hole] –
•
If greater, then use the strap mount sensor.
•
If less, then continue.
6. Confirm depth of the drop-center well near the valve hole:
•
Is it 0.67” (17.3MM) below the humps of the bead seats?
•
If shallower/deeper, then consider using the strap mount sensor.
•
If OK, then continue.
7. Confirm width of the flat base of the drop-center well:
•
Is it at least 0.85” (22MM)?
•
If less, then installation of either the valve or strap mount sensor may not be possible.
•
If OK, then continue.
8. Confirm relative position of the valve grommet-sealing surface of the valve hole of
the adjacent side or top edge of the drop-center well:
•
Is valve hole recessed 0.25” (6MM)?
•
If recessed considerably more, then use the strap mount sensor.
•
If essentially flush or less, then continue.
