Negative Positive
Title: Don't Buy
Review: These valve caps (and others like them) will result in leakage that simultaneously create pressure problems while displaying visual false positives.Tire Pressure caps are a great idea but are not as sensitive as factory Tire Pressure Monitoring Systems and will eventually cause avoidable problems (as described by other reviewers here).In short Tire Pressure Caps, as currently designed and conceived, are NOT ready for prime time. Save your money and your piece of mind.
