The last 3 months we had temps up to 108°F 3 days, and over 95 almost every day. Finally this week relief, temps in the 70's and high 40's at night. Most of the nation has had a summer about like this. This morning I thought of tire pressure on the two vehicles. Instead of the usual 34 it's 25 & 26 on all 8. Got busy and puffed'm right up again. Low tires eat up to 5% of your gas, buy 17 gallons but it burns like 16.
When it dips another 30 degrees, the same thing happens again, the air shrinks in the tire. In the spring the opposite happens, well we don't usually have to let air out though since all tires leak slowly, and faster at high pressure. Air expands and contracts with temperature. This simple rule is another of the scientific reasons we know global warming is not a hoax. As the global average temperature is increasing the atmosphere is expanding. (note I said global, not local, this would be the total of earths surface temp averaged for the year) Clouds cannot leave the atmosphere, they cannot rise above a certain atmospheric limit, yet Thunderstorms are reaching higher altitudes all around the world these last few years as the atmosphere has grown, or inflated. These taller storms contain more energy and destruction. So, check your tires and burn less gas, create less greenhouse gas.
The end of my public announcement, your welcome, send me part of your savings.
When I had my car serviced yesterday, I asked the mechanic to put 32 lbs. of pressure in each tire. I assume that he did.
ReplyDeleteWhit, good on you. Did you know the atmosphere is 1/1,000th the diameter of the earth, that's not really very much room for error.
