Can be either. Alloy rims are usually used w/o tubes, while some steel rims, paricularly older ones may use tubes.
If it is tubeless then patch the tire on the inside. If it has a tube patch the tube.
A tire that is designed to seal on a rim without a tube inside.
Usually, but not always, and it is rarely done. A tube would not conform to the inside arc of some types of tubeless tires, and on others might be overheated by friction and fail.
if the tube is radial too
i have ran a tube for 4 years due to slow leak in rim ..no problem I am now going to replace tire and replace tube at same time and will smooth out inside of tire to be free of rough marks
The inside volume of the tire has not changed, so the pressure will not change.
If inside and outside same pressure that means there is no pressure. The added pressure is what blows the tire up like a balloon and holds the weight of the car up.
Depends on which tube it is you're talking about. If it's the one inside the tire I bet you'll find the answer at www.bicycletutor con.
Before modern tires, automotive tires used a different method for holding the air pressure inside a tire. The inner tube is a piece of rubber shaped like the inside of the tire. The tube has a stem and valve into which air can be pumped. The inner tube is placed inside the tire, the tire is fitted onto the vehicle rim, the stem is pulled through the hole in the vehicle rim then compressed air is forced into the inner tube. That method was used for many years and is still used in bicycle and most motorcycle tires. Today, truck, automobile and many motorcycle tires are "tubeless", meaning that the tire uses a thin coating of sealant material on the inside of the tire surface. The tire seals against the rim, which is designed to fit tight against the tubeless tire.An inner tube is the tube inside a protective outer tire that is generally used to hold air and keep the entire tire inflated to a proper level. They are very fragile in many cases and therefore need some sort of outer protection in order not to become easily punctured. If one does become damaged, it may be possible to repair the inner tube with an inexpensive patch. Also get mor information in detail at Tyreonwheels
To find the size of the rim of your car tires, you look on the side of the tire. It should be printed on the side of the tire, or on the inside of the door of the car.
they hit the walls/side of the tyre and that builds pressure
The center of a tire is called the rim, its what holds the air inside and the car standing ;D
