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.
