[A timely winter repeat from December 15, 2013]

My friend Al reminded me that in cold weather, it’s a good idea to check car tires since the cold will contract air pressure and tires can flatten out.  So, wisely I did.  And sure enough – my front two tires were low. Really low.  It was night.  Freezing cold.  So I drove to a gas station where they have one of those air pumps where you have to pop in 75 cents. I unscrewed the valve caps, had my air gauge at the ready and dropped 3 quarters. The machine kicked in and I applied the hose to the tire valve. Nothing happened.  The hose and valve were frozen.

Now this is not an issue that I’ve dealt with before so I went into the gas station where a lone clerk sat behind a thick glass partition. I explained the problem. “Valve’s frozen,” he said.  Hoookayyy. . .  “Stick the hose up your exhaust for a few minutes while the motor’s running and . . . . [he grabbed a lighter from the shelf and passed it under the window] warm your tire valves.”  “Bring back the lighter,”  he added. 

I went out and slid the hose a couple feet up the exhaust.  And let it sit for a few minutes.  And warm.  Then I fired the lighter and warmed the tire valves.  After a couple minutes, I took a breath, dropped in another 75 cents and applied the hose to the tire valve.  “PFFFFTT.”  It worked like a charm.  Whew!  The tire inflated and I brought the lighter back.  I thanked the clerk (offered him a tip – he declined).  “I used to drive a semi” he said.  “Used to happen all the time.  It’s one of those little tricks you learn.” 

Now you all know the trick.  🙂
