Tpms
Thinking about buying a tpms 507rv. Tired of not knowing what is going on. Any comments on the 507 or any other model. I believe it is a good system but never used one? As always thanks for the great ...

Comparing Crossfire to valve extenders is like comparing manual transmission with automatic.
It is hard to find really good description, but in case of blow-out Crossfire will close good tire after small pressure drop.
Question is what will the central indicator show, the slightly drooped pressure of good tire, or 0 pressure of bad tire.
Either way you will have some pressure drop indication.
I am strong believer in back-up systems and visual indicator sure makes good back up
Hmmm, let's see now. An inner dually valve extender is typically a hose screwed onto the valve stem that extends to the outer wheel where the tire can be filled more easily. A Crossfire on the other hand, has two hoses, one connected to each valve stem in the pair, extending to a central fill point where both tires can be filled at once from a single valve. Yep, that sounds a lot safer to me than one hose. ;)
Unless your TPMS monitor trigger point is set so close that it will detect the small pressure drop before the check valve closes, you won't necessarily have any idea that a tire has failed until it completely blows, potentially causing significant damage. At a local truck shop where I've had work done for years, the tire guys see it happen often enough that they have a large box full of discarded Crossfire units.
