Tire pressure monitoring systems
how accurate are they? worth the 300 price tag? Yes I do realize one answer reflects the other.

We have had Pressure Pro sensors on all 14 tires for going on ten years. Accuracy? They can be off by 4-5 PSI from actual, but that does not matter since you are looking for change.
Before heading out on a trip I check all tires with a good gauge, then look at the PP numbers so I know what they should be showing. Then I can run through the PP every time I stop to watch for potential problems. I run the duals on my fiver (8 tires on 2 axles) at 65 PSI cold, the PP shows 60-61 at that point. So I know that is the correct pressure when I check the PP.
Best thing about it is not having to crawl around in the grass/mud/gravel/whatever to check pressures on a rainy morning!
