Does anyone spit into their tire valve stem after airing up or checking tire PSI?
My dad used to do this for some reason. I was airing up my tires when that thought popped into my head.

i rub some spit over the top of the stem , if it bubbles the valve stem leaks.
Only if the tire is losing air and I don't see any nails protruding into the tire.
Yep, my dad taught me that when I was a kid. Usually end up spitting too much, gets kinda gross. But it works!
The last set of tires I had installed awhile back, the guy did this only he had a jaw full of Redman! Now every time I check the pressure I want to throw up.

And you don't spit into the valve stem... you get a little spit on your finger and place it on the stem to check for bubbles. Be sure to "flick" the stem before installing the cap to remove excess spit so that it doesn't freeze and cause a leak.
wirelessF probably can omit that procedure.....
Old as the hills.
But a good quick check for leakers at this area.
I squirt a bit of WD40 in them before putting the cap on. Makes me feel good so things don't dry out.

I do check the valve stem first with a bit of spit when I have a slow leak, but the only time I've actually had a valve leak it was audible so I didn't need to.- Status
