Feather edge tire wear: Tires are “feathered” when the tread ribs are worn lower/smoother on one side and higher/sharper on the other. This is often caused by a combination of improper alignment settings, such as excessive toe and caster.
Is feathering a problem for your tires?
To understand if feathering is a problem for your tires, it’s easier to feel it than see it. Feathering describes angled wear; the treads that are worn and rounded on one side and sharp on the opposite side. One common cause is bad wheel alignment. For example, feathering often occurs when the front wheels present toe-in alignment.
How does feathering occur?
Imagining how feathering occurs, think of 3 tires that are pointed in an exact parallel line with the length of the car. One tire that is skewed will bear the brunt of the other three who are moving in the same direction.
What does feathering mean on a car?
Feathering describes angled wear; the treads that are worn and rounded on one side and sharp on the opposite side. One common cause is bad wheel alignment. For example, feathering often occurs when the front wheels present toe-in alignment. Feathering could also be a sign of a more serious problem with the car’s suspension.
How do I fix feathering on my car’s tires?
Maintaining a proper alignment on your car’s tires is essential to prevent feathering. If you notice feathering early on, you can often fix it by correcting your car’s alignment. To accomplish this, you’ll need to see an auto technician.
Which tires wear faster?
Since most vehicles wear their front tires faster, within a few thousand miles, the front tires will be more worn than the backs so you won’t want to rotate them then.
Which tire wears faster front or rear?
In most cases, front tires wear faster out than the rear tires as they’re used for braking and steering. However, there are other factors that can determine which tires wear faster on a vehicle, including weight, vehicle usage, power system, and also whether or not the vehicle is AWD, FWD, RWD, or 4X4.
Why do rear tyres wear out faster?
It’s a predictable case of a front-wheel-drive vehicle. On the other hand, if you have a powerful rear-wheel-drive car, the rear tyre will be wearing out faster. This is because the drive or pulling wheels are on the back of the vehicle.
Which tires bear the most weight when braking?
The front tires also have to bear the majority of the vehicles weight when braking. This is because under breaking the weight of the vehicle moves towards the front and rests largely on the front tires.
What is rear tire wear?
High wear on the rear tires is typical, even expected on sports cars and high powered, high performance coupes and sedans. With all of the drivetrain forces being sent to just the rear wheels, the rear tires bear the burden of transferring that power to the pavement.
Why do tires balloon?
When a tire hits a sharp object in the road the force from the weight and speed of the vehicle is focused in the small area of contact. This compresses the tire enough that the inside of the sidewall is pinched and damaged causing a small hole in the inside tire liner layer.
Why do balloons move faster?
You force more molecules into the available space, so a unit area (say 1 cm^2) of the balloon’s surface will undergo increased bombardment by the gas molecules: this means the pressure on the surface increases……. Molecules move faster when they have more energy (which can be supplied as heat).
What are the advantages of inflated rubber tires?
Furthermore, inflated rubber tires also offer a lower rolling resistance (i.e. such tires minimize wasted energy as a tire rolls, which, in turn, decreases the required rolling effort), which is another plus in favor of inflated rubber tires. This is why rubber tires were able to be used in the past, before high speed automobiles were on the roads.
What is the most important factor in tire design?
When it comes to tire design, the most important factor is the ability of air to be compressed and adjust its volume with ease, unlike something made of a solid material.
Why do tires get dirty?
Tires bloom because antiozonant pushes its way to the outer edge of the rubber casing with time. As the element comes into contact with oxygen, it leaves a brown residue on the surface of the tire. Antiozonant is organic and helps tires last longer as it slows deterioration due to oxidation.
Why do new tires look dirty?
It is pretty normal if your new tires look dirty because of antiozonant. This is because antiozonant is an element added to the sidewalls of tires to prevent premature cracking and drying. Due to this element, the tire looks brown, which is also called blooming. To know more about it, read ahead!
Why are my tires not blooming?
Tires do not bloom because of silicone-based tire dressings. Silicone is sticky, so it may allow dirt and dust to hold on to the surface of the tire as you drive, which makes tire sidewalls turn brown. The tire becomes dirty but doesn’t bloom. In this case, you can remove the color with a simple clean, using a brush and some water.
Why do tires turn brown?
Tire sidewalls turn brown mainly because of an element added to the rubber called antiozonant. It saves tires from premature drying and cracking due to the process of oxidation. Tire browning is usually called blooming. It’s a continuing process that can be prevented by thoroughly cleaning and protecting the tires.
Can mold cause tire blooms?
As we know, the cause of tire blooming is antiozonants reacting with the outside environment. Mold doesn’t contain antiozonants, although very occasionally, the mold can cause a build-up of antiozonants on the surface, because they will cling to the mold itself.
Are bald tires bad?
Bald tires are risky to drive on for two reasons – they’re more susceptible to punctures, and they no longer have adequate tread depth to channel water from under the tread. Which means that, when it rains or snows you may lose traction (and control over your vehicle).
Are bald tires dangerous?
It’s the tire’s tread that provides the traction you rely on for a safe and smooth drive. As the miles add up, it wears down. Enough wear and you have bald tires. Bald tires are risky to drive on for two reasons – they’re more susceptible to punctures, and they no longer have adequate tread depth to channel water from under the tread.
Should you replace bald tires when it rains?
Prevent unnecessary expenses and risks by replacing bald tires immediately. When it rains, driving on bald tires increases the chances of skidding or hydroplaning. and possible accidents, needed repairs, and hefty insurance costs. When driving, a vehicle’s brakes are trusted to work no matter the speed. But brakes don’t provide traction, tires do.
What are the symptoms of bald tires?
The most noticeable symptom of bald tires is reduced traction. Newer tires with good tread can maintain traction at higher speeds and quicker acceleration when it’s wet outside. If your tread is worn to the point that you have bald tires, they will struggle to maintain grip in wet conditions.
What causes a bald tire surface?
Uneven tire wear can cause a bald tire surface on some parts of the tread pattern while others may have a significant amount of tread remaining. A wear bar is a raised bar or bump located at several locations around the circumference and across the width of your tire’s tread. Not all tires will feature these indicator bars, however.
Are feathered tires safe?
If tires are feathering, this means that the contact patch isn’t optimal, and handling could be affected. There could potentially be deeper issues within your car should you notice feathering on your tires – ball joints, shocks/struts, or bushings may have failed, causing the toe to change while you drive.
Is tire feathering dangerous?

In most cases, lightly worn tires will not need to be replaced. Do Feathered Tires Make Noise? In many cases, feathering can generate quite a bit of noise.
What is tire feathering?
Tire feathering occurs when the tire starts wearing at an angle. One side of the tread block or the tire rib becomes smoother or more worn than the other comparable side. Feathering is also known as tire scuffing or tire cupping .
What is feathering in driving?
‘Feathering the throttle’ is a technique used to apply the lightest touch to the accelerator propelling the car around the corner with the perfect balance of speed and control without overshooting and crashing. As with everything that requires skill, it’s hard to do and prone to going wrong.
What is the purpose of feathering?
Subscribe to Corrosionpedia for free. What Does Feathering Mean? Feathering is the process of decreasing the edge thickness of a coat film that has been applied to prevent the corrosion of a material. It is done in order to create an even, smooth application area to a surface that has been partially corroded before applying a fresh coat.
Can You Drive on feathered tires?
Generally, it is never recommended to drive on severely feathered tires. Due to the uneven wear, these tires will not function properly. For instance, they may not stop in situations when you really need to stop. Because part of the tire is worn and flat, they may not grip the road quite as well.
What is a feathered position?
The feathered position is such that the prop actually wants to turn backwards. This keeps the prop tight against the prop brake to ensure that the thing does not turn. Feathering means to align the propeller blades such that the pressure difference between the camber face and back face are almost equal and hence they produce no thrust or drag.
Why do people shave tires?
The process removes tread rubber and reduces tire weight by several pounds. A shaved tire’s tread profile will usually result in a slight increase in the width of the tire’s contact patch, putting a little more rubber on the road.
What is the purpose of shaved tires?
Shaving tires happens all the time in road racing and track days type of performance applications. More rubber between the core of the tire (where the belts reside) and the road has more flex, which does not help with adhesion. Shaving the tires helps with side loading g-forces, which means a car can go around a corner better.
Why do tires have hairs on them?
Once the rubber gets injected into the tire mold, the high pressure triggers air bubbles, lowering the solid between them. That’s why the tires need vent holes to release the trapped air. Luckily, leftover rubber on the surface – tire hairs come up to ensure the correct structure. What Are The Little Rubber Hairs On Tires Called?
Is it bad to shave a tire?
Note that shaving a tire will likely nullify its tread-wear warranty. Other retailers may offer a similar service, though the special equipment to shave a tire’s tread isn’t common. How Worn Is Too Worn to Shave a Tire?
How do car racers shave their tires?
Car racers shave their new tires, lopping off the top tread layers to improve their grip on the tracks. Slick tires have better grip on dry pavement, such as racetracks. Tire shaving is a low-tech, but specialized process. It requires a special machine and an experienced operator at the controls.The tire is mounted on the shaving machine.
What do bald tires feel like?
If the treads are gone and the surface of the tires is smooth, you have bald tires. If you forget to look, your tires will let you know by losing traction on wet roads, skidding when you come to a sudden stop, or becoming harder to steer at high speeds.
Why do tires go flat?
The most common cause of a flat tire is by a puncture due to a sharp object, such as nails or glass. Avoid puncture blowouts by driving around debris in the road or in parking lots whenever possible. Valve stem issues are another common cause of tire problems.
Why do tires sing?
Uneven wear is a leading cause of tire noises because contact between the road and uneven tires isn’t uniform. The unbalanced tread depths cause tires to emit loud noises while driving. Usually, you’ll hear sounds caused by uneven wear coming from one tire. Alignment issues can also cause tire noises.
Why are my tires making a loud noise?
Once tires are installed on a vehicle, there is much that can go wrong, leading to excessive noise. Abnormal tire wear, such as feathering or cupping, can be caused by alignment or suspension problems. Once the tread surface is no longer smooth, the tires will generate more noise.
Why are my tires squealing?
Normal tire wear, when tire tread depth is very low, can lead to the same noise. Combined with excessive speed, this can cause tire squealing and possibly a loss of traction. To prevent excessive noise, ensure that tires are properly inflated, slow down during turns, and have your suspension checked for damage and proper alignment.
Why do my tires hum a lot?
Pretty much every car will experience some tire hum. Tire hum is the usual noise of your tires rolling on asphalt. However there are a few reasons why tire hum could be louder than usual: Having tires with a higher than needed load index will create more noise Tires with a greater than necessary speed rating will create more noise
Why do low profile tires make more noise?
Lower profile tires have less rubber in the sidewalls, contributing to the increased noise levels you’re hearing. Because there is less rubber sidewall to absorb the sound, low-profile tires often make more noise. Their increased noise offsets the increased traction these tires provide.
Why do tires rub?
Tire rubbing is what occurs when a tire is coming in contact with part of the car. Usually when using oversized tires or wrong size, offset, or width will cause tire rub. Tire rubbing is dangerous and can cause a tire blow out.
What causes tire rub?
Another potential cause of tire rub is suspension problems. If your suspension is not functioning properly, it can cause the tires to rub against the fenders or bodywork when turning. This is most often caused by worn out suspension components or a damaged suspension system, especially if the suspension has collapsed.

How do you know if a tire is overinflated or underinflated?
An overinflated tire will wear in the center of the tread, while an underinflated one will wear more on the two sides than in the center. The best way to avoid uneven tire wear is to check their pressure at least once a month and make adjustments accordingly. Properly inflated tires will also help maximize your gas consumption.
What should I do if my bike tire slips?
If the tire slips, tighten a bit more. Once the wheel no longer slips when yanked by hand, get on the bike and ride. If the wheel skips, tighten the knob a bit more. Repeat as necessary. Lastly, after your workout, loosen the drum so it’s not pressed against the tire.
What causes irregular tire wear?
Irregular tire wear can be caused by tires that are not properly balanced. Rebalancing your tires every 10,000 miles is recommended because tires fall out of balance over time. Lost wheel weights, bent rims, or damaged tires can cause irregular tire wear.
Do feathered tires make noise?
Abnormal tire wear, such as feathering or cupping, can be caused by alignment and suspension problems. In turn, feathering and cupping generate noise because the tread surface is no longer smooth.
Why do feathered tires make a noise?
Since feathered tires are essentially being dragged down the road fuel economy will also be reduced. The noise caused by feathered tires is commonly described as a roar or a bit like the knobby tires of a 4×4. Some have also confused the noise with a bad wheel bearing.
Are feathered tires causing a roar?
The noise caused by feathered tires is commonly described as a roar or a bit like the knobby tires of a 4×4. Some have also confused the noise with a bad wheel bearing. Most people don’t realize how loud their tires have gotten as it has gradually increased over time.
How do you know if a tire is feathering?
Irregular tire wear can be difficult to troubleshoot, but feathering is usually easy to identify. The feathery bits of rubber hanging off of the left or right side of your tread blocks is a telltale sign. Often a bad wheel alignment is the problem, but suspension system problems are also sometimes to blame. What Does Tire Feathering Mean?
Can feathered tires cause shaking?
Abnormal tire wear (cupping, scalloping, feathering) from an out-of-alignment or damaged suspension system will cause tires to be noisy and vibrate. Your repair shop should check for worn or bent suspension parts as part of a wheel alignment or when diagnosing abnormal tire wear.
Why are my tires feathering?
Tire feathering is caused because the rubber bounces as you drive down the road. The tire is not remaining in contact with the road as it should. Bouncing can be caused by bad wheel alignment, worn suspension parts, out of balance tires, a bad bearing, poor tire quality or low air pressure.
Should I rotate my tires to remove feathering?
No, there is no truth to that. Rotating the tires is a way to remove feathering. You might want to find another shop or another alignment tech. For a vibration at about 60 up, I’d check tire balance first. Since the rears are feathered, the alignment needs to be checked, too.
What do cupped tires feel like?
Symptoms of Cupped Tires This is due to those unevenly worn patches of tread rubber causing odd noises while rolling. Vibrating or Shaking: You may feel some excessive vibrations either in the steering wheel or in your seat as you drive.
What does a cupped tire sound like?
The noise of cupped tires is growling or grinding, very similar to that of a bad wheel bearing. It’s important to be able to distinguish the sounds. The noise generated by cupped tires will increase as you speed up. The wheel bearing noise will change along with the direction of the part.
