What would happen if automobile tires had no treads on them?

What would happen if automobile tyres had no treads on them?

On dry, firm roads, pretty much nothing. Treads are there to deal with water and soft surfaces. Modern treads are also designed to help avoid hydroplaning on very wet roadway, without treads a car would very easily hydroplane (completely losing contact with the roadway when there is even just a little water over the roadway, causing the car to 'float' with no traction whatsoever).

How you could improve tire treads?

Buying new tires would be the best way to improve tire tread.

What would happen if all the air in all the tires in the world was released at once?

There would be a lot of flat tires.

Do treaded tires offer better braking in aircraft?

The more surface area of the tyre that is in contact with the road, the more friction (stopping power) you generate. the reason you have treads on tyres is so water/dirt/snow can flow into the tread gaps. without treads, the water would have nowhere to go and the tyre would never actually touch the ground (hydroplaning). To answer your question, adding treads offers little benefit in dry conditions, only when it is wet/snowy/dusty on the runway.

Why should you fill automobile tires with air not with water?

Water is way too heavy to put in tires, plus in the winter it will settle and freeze so your tires will be off balance. Also about the winter part, if you completely filled your tires with water and let the water freeze, the tires would explode, since water expands when it freezes.

What would happen if you put Nascar tires on a regular car?

When it rains or snows, you will have NO traction.

Do rubber tires decompose?

Given enough time yes, they will decompose. It would take thousands of years for this to happen.

Does friction increase or decrease when tires are worn out?

Depends on what you're thinking about. On a hard, even surface a tire w/o treads can generate more friction than a tire with treads, as it will have a bigger engaged surface area. OTOH a tire with little/no treads will be prone to hydroplaning, which is very low friction.Then if you're talking about a soft surface a smooth tire will have less friction than a treaded tire. On a soft surface the treads can bite in which offerc more engagement than a smooth tire that might just slide on the top.If you were to look at the rolling resistance of the wheel as a whole, then a worn out tire will roll lighter than a treaded tire. A big part of rolling resistance is the energy lost in deforming the tire as it rolls along. As there's less rubber in a worn tire it will deform more easily, offering lower rolling resistance.Depends on road conditions.On a firm, dry surface a smooth tire will have more friction than a treaded tire. That's why race cars tend to have smooth tires AKA slicks.The reason why treaded tires are generally required for road use is that slick tires do very poorly in rain. When you drive through a puddle, water gets squished between the contact patch and the road, and w/o the tread pattern allowing water to escape, the tire is lifted off the road and hydroplaning occurs.Slick tires also do very poorly on softer Surfaces where treads would have dug in and found grip.

What could be making a humming sound coming from your eighteen inch rims loudest at twenty mph and the wheels are on tight and the tire seems not to be hitting anything?

The tires themselves may be the cause of your concern. If the tires have deep treads on them they will make some a strange humming sound. I would still advise having a mechanic check it out just to be on the safe side.

How would one install non slip stair treads?

There is a video on the DIY (Do It Yourself) website which explains how one would install non slip stair treads. There are many steps to follow but they are explained clearly in the video.
