What does 205 mean for tire size?
It means that the part of the tire that is in contact with the road is 205mm wide.
Why the tractors have a broad tires?
Tractors have broad tires because there is more contact with the ground and less compaction. The bigger the tractor tire the narrower it is a 52" tire is narrow but we have a 32" tire that is 34" wide.
Why do tires have less friction when it rains?
Because the water on the ground acts like an oil diminishing the grip. And when the ground is wet the water molecules resides between the ground and tires so, the tire is not in total contact with the ground.
How does tire presser affect traction?
The tire pressure directly affects the surface area of the tire making contact with the road... an underinflated tire has a wider aspect ratio against the road. This reduces ground pressure, which means that the weight of the vehicle is distributed over a wider area of the surface being driven on than a properly inflated tire. While this is desirable for something like mud bogging, what it means on a regular roadway - especially in inclement weather - is reduced traction, skid control, and handling.
When a tire is under inflated what part of the tire grips the road?
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.
Why do you need tread on tires?
The "tread" is the part of the tire that is supposed to touch the ground. A tire with no tread would be a tire that is not supposed to touch the ground. You may be wondering why tires have a pattern of grooves (a.k.a., voids) in the tread. They're for bad weather. The grooves allow rain, and (if they're wider) mud and snow to squelch out from under the tire so that the tread can come into contact with something solid on which to get a grip.
How does friction act on a car?
According to wikipedia friction is defined as: "the force resisting the relative motion of two surfaces in contact or a surface in contact with a fluid (e.g. air)." Thus there are would be 2 locations friction would occur on a moving vehicle: (1) air resisting the motion of the vehicle; (2) friction between the tire and the ground. Two types of friction can occur between the tire and the ground, a) static friction, and b) kinetic friction. Static friction is when the tire maintains grip or traction on the road surface, whereas kinetic friction (as the name implies) is when the tire is moving relative to the ground. To illustrate static friction, consider for a moment a dot on the tire's surface. Your vehicle is moving forward (let's say it's moving very slowly), and your tire rotates so that the dot comes into contact with the ground at a certain point. Since a car tire compresses a bit on the road's surface, there's approximately 3-4 inches of tire flat against the road at any given time. As your car moves forward, the tire rotates, and once the dot touches the ground at a given point, the tire and the ground move at the same rate relative to the car. That is, the dot on the tire and the point on the ground remain in contact until the tire reaches the end of that 3-4" strip of contact, when it is pulled upward from the ground to rotate around top and back to the ground. An example of kinetic friction from the illustration above would be that the dot on the tire reaches a point on the ground, but the dot and point move away from one another. In real life this would be if you hit the brakes and skid, or if you hit the gas and burn out or spin your tires (e.g. in the snow or mud). The problem with kinetic friction is that it is weaker than static friction. Thus, when you hit the brakes, if your tires lock up (you'll hear the squealing tires against the road) you are now in kinetic friction and your car will slow down less (actually speed up) compared to when your tires were in static friction with the ground. That is why you pump your brakes... also why anti-lock braking systems (ABS) were developed.
What is tire tread width?
The width of the contact patch of the tire on the road.
What does it mean when you drive and you go over inclines and you can hear your car scrape the ground?
Bottoming out can be caused by many thingsLow tire pressureWrong sized tire for the vehicleBad shocksBroken springsOverloaded vehicle
How do you remove tire from 2005 ford escape you took off the lugs but the tire wont come off?
You have to safely jack the vehicle, so the tire is off the ground. Or hit the tire with a large hammer once it is off the ground.
Correct tire pressure for harley Davidson touring bike?
The tire pressure is dictated by the tire manufacturer. Look in the side walls of the tire or contact the tire manufacture.
