Had my BB checked out $$$$
Hi, high pressure tires and valve cores leaking after you check your pressure or add air is a frequent problem. When I need to check or add air I always have a can of silicone spray with me. After I take a tire pressure reading if the valve core starts leaking, I spray some silicone on the end of the tire chuck from my air compressor hose and then put it on the valve stem with the leaking valve core and put a shot of air mixed with silicone in. This lubricates the valve seal and it stops leaking, then if the tire was a little lowI can add air and the valve core will seal afterI am done adding air. Silicone is good for rubber seals inside the valve cores and doing thisI haven't replaced a valve core on my 1985 PT40 in allmost 10 years, andmy tires hold their air
pressure very well, I have 2 tires that over the winter might loose up to 10 psi.The valve core seals just need a little lubrication. Wayne

Get some metal valve caps with rubber seals inside. Check the seals regularly to ensure that they are still there and not damaged.
2. Get a valve wrench and a bunch of the valve cores. Replace the leakers.
I found a vendor on the Internet that seemed to have "good quality" valve cores (they were described as "high temperature" ) and some metal valve caps. They were packaged in bags of 100, but weren't terribly expensive. I bought a bag of each.
I've probably gone through a twenty or more of the valve cores over the past couple of years -- and it's handy when a dropped valve cap disappears far under the coach to just get another one out of the tool box.
Be especially careful of the pass-through valve caps (the ones where you can put air in through the cap). They're usually a recipe for leaks. (Previous owner had them on all tires. I suppose he used 'em because they were also an extension which on my coach is a plus for the steer axle.)
