A worn tire reduces friction and tracktion, this could be dangerous in bad weather conditions.,

A2

A worn tyre would actually improve friction in dry conditions, because the surface area touching the road, will be greater without tread.

This why racing cars use 'slicks' in dry conditions.

The problems arise in wet weather. The thinnest film of water between the tyre and the road, will cause a sudden decrease in friction, 'aquaplaning'.

The tread is there purely for wet conditions.

How does a car tire get worn away by friction?

The heat from the friction of the tire rolling at a high speed on the street causes the rubber to slowly burn up.


Effect of friction on the motion of a vehicle in the context of tire surface?

the more worn-out the tyre the lesser the friction produced.newer tyres are better in stopping cars as they can produce greater friction. the worn-out tyre has a surface which is plainer than the new tyre. lesser surface irregularities leads to lesser friction.


How do tire treads work to increase or decrease friction?

Tire treads increase friction by providing more surface area for the tire to grip the road. The grooves in the treads help channel water away, preventing hydroplaning and maintaining traction. However, worn treads can decrease friction, leading to less grip and potentially dangerous driving conditions.

When the road on a tire has worn out so that the tire is bald the tire will have high or low friction on a dry road?

The tire has almost no traction and can blow out at any time. It will also hydroplane in very little water. A tire should be replaced when there is 2/32 tread left. A bald tire is an accident waiting to happen.


What are the different tire wear?

if it is worn down the middle it means the tire has to much air in it. if the two sides of the tire worn there is to little air. if it is worn at one side of the tire the tracking is out


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.


Why would the steering wheel wobble on 2009 Subaru impreza?

Tire out of balance, defective tire, bent wheel, loose wheel, worn steering parts, worn or loose wheel bearing, worn suspension parts.


Would a worn tire make a noise?

No, I've had many and if anything they are quieter.


Where would the tread of a tire be worn out if the tire were under-inflated?

Underinflated tires wear faster on the sides than the middle.


Why does your steering wheel shake?

Your automobile may have a tire out of balance or a worn part in the front end causing this "shimmy" effect .
