Usually the tire pressure does increase as they heat up with friction. However, this is very small amount and is much reduced with the newer design of tires. I would estimate the tires only heat up a couple of degrees. They may also heat up due to the heat of the highway on summer days.

No...tires heat up a LOT when you drive, because of heat caused by friction. The air pressure goes up 1 psi per 10 degrees temperature increase. What has changed with radial tires, is their handling doesn't radically change with air pressure like it did with bias-ply tires.
physical
The inflation of a tire is considered a physical property, as it relates to the tire's volume and pressure. It is not a chemical change, as the composition of the tire material remains the same.
No, a tire losing air is a physical phenomenon caused by air molecules escaping through tiny holes or leaks in the tire. This is not a chemical reaction because it does not involve a change in the chemical composition of the tire or the air.
When air is pumped into a tire at a constant temperature, the pressure increases because the volume of the tire decreases as more air is added. This causes the air molecules to be more tightly packed together, resulting in higher pressure within the tire.
physical change. the rubber is still rubber and the air is still air, so NO chemical change has occured
An inflated tire is generally heavier than a flat tire due to the air pressure inside it. The air adds weight, so when a tire is fully inflated, it contains more mass compared to when it is flat. However, the difference in weight is relatively small, as the air inside the tire is not very dense.
Any tire inflated with a gas (air or nitrogen ) is a pneumatic tire.
Any tire inflated with a gas (air or nitrogen ) is a pneumatic tire.
Inflating a tire with air is a physical change because it is not changing the tire chemically. It is only changing the physical appearance of the tire.
yes, but it is dependent on how hot the air was when the tier was first inflated.
Depends on how you look at it. Tire + lots of pressurized air inside will weigh a tad more than tire with only a little air inside. But the actual tire casing will weigh the same whether it's inflated or not.
Air pressure is a measure of how much air is in a tire, or how much it is inflated. Air pressures are written on apanel on driver door frame and on tire sidewall. they are very important to tire wear.
When a tire is properly inflated it will be level to the ground. Over inflated and the middle of the tire has the most pressure on the ground. Under inflated and the sides of the tire have the most pressure on the ground.
The same as a tire that has not been inflated.
A bike pump works by using a handle to push air into the tire through a valve. When the handle is pushed down, it compresses the air and forces it into the tire, inflating it. The valve on the tire allows air in but not out, so the tire stays inflated.
To put air in a tire without using a gauge, you can visually inspect the tire to see if it looks low on air, then use a manual pump to add air until it looks properly inflated.
A pneumatic tyre (or in North America tire), is a tire which is inflated by air. This is in contrast to a solid rubber tire which some wheelchairs might use.
