why the tar squeezes out of the street cracks in warm weather?

It expands and contracts from the heat and with the cold.

It is not dry heat . Lot of sultryness and salt too .Humidity high.

It's a chemical reaction between the materials used in country roads and natural raindrops.  The drops gather together (congeal) and become frogs.  Where I grew up it was suburban city concrete sidewalks and worms.

When heat radiates off the earth it causes the air right above the ground to heat up and then refract ( bend ) light so that light coming from the sky gets sent to our eyes like it was coming off the ground.  Drive down a highway in the summer.  Look off in the distance and it will appear that there is water on the ground.  This phenomenom (sp?) also happens in the dessert and can trick one into believing water is just a few hundred yards away.

If you tint it, it adds to the heat being absorbed to the glass.  Dark things absorb more light, light colors reflect more.  So the window should then start becoming hotter than before and hence why you should start seeing it crack now.  Also is the window facing east, it would explain the time of day it is cracking.  Now the window will not only heat to a high temperature, it will do it faster from the however cold it will have gotten overnight.

The tires have nothing to do with it, between the dirt and moisture on the outside of the tires and the metal belting inside the tires, the rubber won't insulate you.  However, since the frame of the car is metal and forms an unbroken 'cage' of sorts around you, most likely the electricity will flow through the metal around you and into the ground.  This assumes that the doors are shut and you don't touch the metal parts of the frame that you can reach from inside the car.  Then again, lightning is unpredictable and often behaves strangely, so almost anything is possible.

Tobacco tar isn't the same as what you put on your roof as a sealant (which is more likely to be "pitch", a petroleum by-product).  Tar is just a generic term for the sticky organic by-product of burning tobacco leaves that tends to remain in the lungs -- obviously not good for the health.

Woah!  Stay inside, try to have your car in an elevated area or a garage, and put sandbags near your doors if water leaks under them.  We're supposed to get crazy thunderstorms and hail this afternoon, with tons of rain, too.  Good luck!

When it is cold and dry outside, the friction of your car going through the air creates static on your car. When you get out, you provide the shortest path to ground and the static electricity goes through you. If you hold onto the metal on your door while you are getting out, you will not be shocked.

because the moistness causes friction

Maybe the layer that you leave on the road is so thin that it just blows away or turns into dust.  Then, it doesn't accumulate really since it floats around in the air just like all the other small pieces of dust.  It's probably not that much rubber anyway.

When you pump in the air the energy you're using to force it in makes the air warm. When you ride, this makes the air inside the tyres warmer still. All this warming makes the air expand - which is great, it makes the tyres firmer.\n\nWhen you leave the bike static in a cold place the air cools and contracts - so the tyres get softer. \n\nAlso, there is always a bit of leakage - so when you leave the bike for a while the tyres will have deflated a little.

Hot and cold air converging over an area of low presure.

Pitches r different due to different environmental conditions, atmosphere taking into account the humidity level,amount of rain.\nAnd moreover,it also depends on the amount of work done on it like rolling again and again!

With the air holes closed, there is a shortage of oxygen and the hydrocarbons in the gas do not burn completely. Some carbon is not burnt resulting in soot

It's not cold enough.

Because the soft ground and the trees hold more moisture than the concrete and steel that's found in the city.
