Check the tire for signs of cracking or separation in the treads. Look for signs of the steel threads showing through if you have steel-enforced radial tires. Monitor the treads for uneven wear. If a belt slips, it will create an odd shape to the tire that results in uneven wear based on the location of the slipped belt.
Why do steel belted radial tires fail?
Due to the difficulty in obtaining adhesion of steel to rubber there is a potential for tread separation of all steel-belted radial tires. This is true especially at high speeds in hot weather. tirecutview Industry records verify that tread belt separations are the most common mode of failure of steel belted radial tires.
What is the speed limit for radial tire belts?
This sign is most significant at low speeds from 5 to 30 miles an hour and higher speeds from 50 to 70 miles an hour. The belts in a radial tire extend across the entire tire from one side to the other. One purpose of these belts is to enhance the strength of the sidewall.
What are steel belted tires?
Steel belted tires, also known more commonly as radial tires or steel belted radial tires, have been the technology standard in tire construction since the mid 1970s. The tire is featured by its construction of a steel wire mesh between the tread and the body ply of a tire.
What happens if you puncture a steel belted radial?
The design of the steel belted radial tire is such that a puncture is more likely to simply cause a slow loss of air, which can be repaired by a patch, plug, or combination of patch and plug. The tire should then be able to serve out its useful tread life with untoward effect.
Are steel-belted radial tires good?
Choosing Steel-Belted Radial Farm Tires Radials provide better traction, lower fuel consumption, and offer more comfort—and the addition of steel belts in the construction of radial tires can super-charge their performance advantage over bias tires and their non-steel-belted radial counterparts.
What causes steel belts in tires to break?
Broken belts in tires usually come from defects during the manufacturing process. However, they can occur from improper mounting, degraded and aged rubber, extreme heat, oversteering, and debris. Belts break into small pieces and change the shape of the tire.
What is the #1 cause of problems with tires?
Tread separations are the most common cause of tire failure. Contrary to popular belief, tire blowouts are not the pervasive problems they once were. Instead, the most common cause of tire failure for modern cars is tread separation. This occurs when the belts under the tread of the tire come apart.
Why do radial tires separate?
Tread separation is the most common type of tire failure. It occurs because of the way tire companies design and manufacture modern steel-belted radial tires. These tires feature two steel belts that wrap around the tire. The tread adheres to these belts, and this entire assembly is then bonded to the sidewalls.
What does it sound like when a belt breaks in a tire?
Thumping Noise Is Heard Aside from vibrations, another notable sign that you have a broken belt is when you start hearing a thumping noise as you drive along the highway. You may notice this sound more when you are driving at slower speeds because there will be less road noise to interfere with the noise.
How much does it cost to fix a tire belt?
A typical serpentine belt start at around $25 and goes up to $75 at most.

What is the most common cause of tire tread separation?
One of the most common causes of tire tread separation is a manufacturer's defect, wherein something went wrong in the bonding process of the tread and steel belting section of the tire casing, and the tread did not adhere properly.
What does steel belted radial mean?
Steel belted bias uses two or more layers of nylon cord PLUS two steel belt layers beneath the tread. This construction creates a reinforced carcass (the network of chords that gives the tire is strength) that offers additional support and a more rigid inner material to bond with the tread.

How to tell if you have a broken belt?
Aside from vibrations, another notable sign that you have a broken belt is when you start hearing a thumping noise as you drive along the highway. You may notice this sound more when you are driving at slower speeds because there will be less road noise to interfere with the noise.
Why does my car make a thumping noise when I put on a belt?
Because the belt has created an uneven surface, the rubber will hit the pavement unevenly. As it does, the area right after the broken belt will strike the surface harder, creating the thumping sound.
Why does a tire vibrate when it's broken?
Because the steel belts inside your tires provide support for the rubber, one broken belt will make an area on the tire uneven, resulting in the vibrations. How the vibrations present themselves can give you a clue as to which tire has the broken belt.
What to do if you see a hump in your tires?
If they see a hump in your tires, and you have noticed other signs, use extreme caution while driving on the tire, the rubber in this area has been severely weakened because there is no longer a stable supporting structure.
Why do radial tires wear faster?
Because the fabric stretches frequently in turns and at other times of stress, the tire wears faster than a radial. in radial construction, the cords run side by side rather than on the bias, and a.. belt, usually made of steel, is placed wider the tread. Radial tires reduce rolling resistance arid thus improve mileage.
What is the difference between radial and bias?
The basic difference between radial and bias construction is the way in which Abe fabric is woven and the application of a belt over the foundation of the tire in belted tires. In bias tires, the fabric crosses like the letter “X.”. Because the fabric stretches frequently in turns and at other times of stress, the tire wears faster than a radial.
How many radials were in 1977?

Frank Holeman, director of the Tire Industry Safety Council, called the response a “herd reaction.”.
Why do steel belted radial tires leak air?
Design and manufacturing defects can accelerate this leakage rate. Because of the air permeability of steel belted radial tires almost all tires are run underinflated at some time during the course of their lifetime and, as noted, this is usually not observable by the consumer.
Who reports steel belted radial tires?
The truth of the matter is, comprehensive analysis of steel belted radial tires is reported to tire manufacturers by Smithers Scientific Services so that all of the tire manufacturers are routinely provided with the physical properties and chemical makeup of their competitors’ products.
What is the safety belt on a tire?
The tire design problem can be overcome by use of proper wedges and cushions at the belt edges, an appropriate under tread protecting the steel belt edges, and a nylon overlay design modification known as “safety belts”, widely used in tires manufactured for the European market as well as many American tires.
What happens when a tire does not lose pressure?
Even when the tire does not lose pressure the driver often loses control of the vehicle when the tread and upper belt separate from the carcass of the tire resulting in vehicle loss of control and rollovers that have resulted in thousands of serious injuries and fatalities.
What happens when a rear tire is involved?
When a rear tire is involved, this results in a braking action in the direction of the tire failure. When the driver attempts to correct for this braking action the vehicle usually goes out of control in the opposite direction. This is often mistakenly referred to as overcorrection.
When did tire belts break?
It is important to note that all manufacturers have suffered steel belted radial tire tread belt separations since the 1970s. These tire failures are often referred to as “blowouts”. However, not all tread belt separations result in air loss, so many are not blowouts.
What is bare wire on a tire?
When examining a separated tire one should look closely at the separation interface to determine whether there is any rusty wire, bare wire or brassy wire exposed. Corroded wire is usually evidence of moisture contamination during manufacturing. Bare wire is an indication of a manufacturing adhesion defect.
Do steel belted radial tires have a puncture resistant tread?
My cautionary tale about steel belted radial tires. Yes, they are more puncture resistant in the tread area. My experience has been that the sidewall bulge is very vulnerable to punctures, in my case from corn stubble. This was with 15” trailer tires on a wheel rake. Constant problems with sidewall punctures, even with new tires.
Can you move a tire sealer to the next tire?
You can move the sealer to the next tire by scooping it out. The good sealers with the fibers will clog the pump that comes with the pail. That's a good indication of how well they work. Aggravating yes but if it can clog the pump think what it does to holes.
How to fix a tire with a hole?
In summary, the only way to properly repair a tire with a hole is to demount the tire and apply two types of patch -- an inner flat patch as well as a tread plug -- or by using one of the combination patches that does the job of both .
What happens if you patch the same tire before?
If the second hole occurs on the same cord or on opposite sides, the cord has been weakened to the point where it could let loose inside the carcass, leading to blowouts or a severe tire imbalance.
What is a tube tire patch kit?
Tube or inner tire patch kits typically include a few patches of varying sizes, cement and a stitching tool, used to push the patch over the injury evenly to prevent it from curling before the adhesive can cure.
Can you use a tire plug on a radial tire?
Tire failure can have disastrous, and expensive, consequences. Photo by The Tire Zoo. Whether to use a tire plug or patch on a radial tire can be a controversial subject, especially depending on where the injury to the tire has occurred. Because of the flexibility of the sidewall on a radial tire, no original tire manufacturers recommend using any ...
Can you patch a motorcycle tire?
For instance, most motorcycle repair facilities will not patch a tire leak, even though many motorcycle tool kits are equipped with a tire patch kit. This seems reasonable, given that the width of a motorcycle tire places it firmly within one-inch from the tread edge on most injuries.
Can a radial tire be repaired?
Because of the flexibility of the sidewall on a radial tire, no original tire manufacturers recommend using any kind of repair system on a tire's sidewall. Virtually every tire manufacturer states that a radial tire with a sidewall leak should be replaced, without exception.
When did Firestone recall tires?
At one point, in 1977 , Firestone recalled 400,000 tires after it determined that some 25,000 tires produced at its Decatur, Ill., plant, were defective. The recall was voluntary but it followed arm twisting by the government.
