If the volume doubled, its pressure halved and vice versa, when the temperature is held constant.Īs well as the volume/temperature relationship, Gay-Lussac extended the work and experiments, from a century earlier, of the inventor Guillaume Amontons to show that, in a fixed volume of gas, pressure was directly proportional to absolute temperature. He found that the pressure of a gas had an inverse relationship to its volume.

Robert Boyle had been carrying out experiments with air, which he proposed was full of particles connected by tiny invisible springs. The first piece of the ideal gas puzzle came in the 17th century. He was working on the relationship between the volume and temperature of a gas, building on work carried out several decades earlier by the inventor and mathematician Jacques Charles who had shown that volume and temperature were proportional – heat a gas and its volume will increase and vice versa, as long as the pressure remains constant. It is also a fundamental component of the ideal gas laws, first written down in the early 19th century by the French natural philosopher Joseph Louis Gay-Lussac. It is an intuitive idea that bubbles of air will expand if you heat them, as long as the pressure remains constant. All this time, the pressure of the air inside those bubbles has stayed the same (you know that because cakes don't usually explode when you slice them after cooking). It is obvious what has happened – the air bubbles that you have carefully folded into the mixture during the preparation and the little bubbles of carbon dioxide created by the baking powder have expanded as they are heated in the oven, taking the rest of the cake with it. When you put it in the oven, it starts off at a particular volume and then, an hour later, it has risen to perhaps double its size. As the vehicle is driven, the tires heat up and the pressure rises, which makes it more difficult to set them to the correct cold-tire pressure.T hink of a cake. Measure the pressure with the tires cold, before they’ve been driven more than a mile or two.If your car has a limited-service (aka a space saver) spare, also check that it’s inflated to the pressure specified on the placard-usually 60 psi. Don’t go by the 'maximum inflation pressure' imprinted on the tire. This is printed on a placard in the car, either on a doorjamb, the fuel-filler door, or on the inside of the glove box lid. Set the tires to the automaker’s recommended tire pressure.A good tire-pressure gauge is available for as little as $5 to $15 at auto parts stores. At least once a month, use a tire gauge to check the pressure in all four tires and the spare.This effect can be exaggerated on a soft surface, such as a dirt road or gravel driveway. Modern tires bulge slightly, making them look a little underinflated, even when they’re not. Don’t judge the pressure by eyeballing a tire.Don’t ignore vibration: Have the vehicle serviced at once. It could also signify internal tire damage or a suspension problem. Tire vibration may be a sign a wheel is misaligned, unbalanced, or bent. These signal potential weak spots that could lead to tire failure. If you see a bulge or blister on the sidewall, replace the tire at once. If you can see Abe’s head using the penny, the tread is too worn and the tires need to be replaced right away. If you can see the top of George’s head, about 4/32nd-inch, then it is time to shop. Insert the quarter into a tire groove with Washington’s head toward the tire (shown below). Alternatively, you can use a quarter and penny as treadwear indicators.Inexpensive tread-wear gauges are available at auto-parts and tire stores. When the tread wears down to these bars, it’s time for new tires. Most modern tires have tread-wear indicator bars running across the tread, which signal the minimum allowable tread depth of 2/32-inch.

This can be caused by improper inflation, misaligned wheels, damaged tires, or problems with suspension parts.

If you find any of the following conditions, the tires should be taken to a shop for professional evaluation and likely replacement: It takes just a minute to walk around your car, looking for warning signs. Visually inspect your tires on a regular basis-ideally weekly.
