New To Me 98 Tahoe, Green

[YukonGTmaster]

Or again yesterday.

How can it only leak or go flat so rarely? Penetrated object wiggling and sometimes sealing? Valve stem intermittent?

Might be worth getting a Shrader Valve tool in the end of the valve stems, and see if you can snug them up a bit. I run metal valve caps with o-rings on them.... until the tire shop throws them out, at tire change time, and puts green plastic ones on again.

I did that and went through them all. No leak downs since, but they only rarely leaked before, so I'm not sure it mattered. Left front goes down just a bit, but not much.

I can't believe I've had this thing for a year and a half.
