Tried Tested And Guaranteed
Manufactured from only the highest quality materials, Continental sets high standards particularly in safety. Before any Continental innovation goes into production, it is tested intensively. Testing is carried out on every winter and summer tyre. This is done under all kinds of weather and road surface conditions, using the most modern testing methods and measuring technology.
Every test follows one simple purpose: making driving safer.
* 205/55 R 16 91V ContiPremiumContact 5¹ As of 2010 stringent mandatory limits are in effect in the EU explicitly for plasticisers classed as harmful to health. Thanks to the use of alternative types of oil, Continental tyres remain well below these limits.
The Typical Radial Tire Consists Of Nine Main Parts
1- Inner liner:An airtight layer of synthetic rubber
2- Carcass Ply:The layer above the inner liner, consisting of thin textile fiber cords bonded into the rubber. These cables largely determine the strength of the tire and help it resist pressure. Standard tires contain about 1,400 cords, each one of which can resist a force of 33lb.
3- Lower bead area:This is where the rubber tire grips the metal rim. The power from the engine and braking effort is transmitted from the rim of the tire to the contact area with the road’s surface.

4. Beads:They clamp firmly against the tires rim to ensure an airtight fit and keep the tire properly seated on the rim. Each wire can take a load of up to 3, 968 lbs without risk of breaking. There are eight of them on your car – two per tire. Thats a massive 31,746 lbs of resistance strength. An average car weighs about 3,307 lbs.
5- Sidewall:It protects the side of the tire from impact with curbs and the road. Important details about the tire are written on the sidewall, such as tire size and speed rating.
6- Casing ply:It largely determines the strength of the tire. It’s made up of very fine, resistant steel cords bonded into the rubber. This means the tire can resist the strains of turning, and doesn’t expand due to the rotation of the tire. It’s also flexible enough to absorb deformations caused by bumps, potholes and other obstacles in the road.

Q: What Does The Mileage Warranty On My Tires Mean
A: Your tires mileage warranty means that the manufacturer will cover them against defects for the duration of that warranty and that the company expects its tires to last at least as long as the warranty under ideal conditions. This does not mean that only getting 25,000 miles out of a 50,000-mile tire will net you a new set of tires if you complain. It means that, after an inspection, you may be entitled to a new set of tires at a prorated price, which will depend on how many miles you have left on the warranty. If you failed to rotate the tires or take care of them properly, you can expect some pushback when trying to make a warranty claim.

How Do They Break Down
Tire tread patterns help determine a vehicle’s grip on the road, as well as handling, maneuvering, and breaking. But better grip can also mean more friction. And as we drive, abrasion causes bits of our tires to break off.
A 2013 report by Tire Steward Manitoba, in Canada, found that passenger light truck tires lost nearly 2.5 pounds of rubber during their service life . The Kohl study found that Americans produce the most tire wear per capita and estimates that, overall, tires in the U.S. alone produce about 1.8 million tons of microplastics each year.
Exactly how much of that waste ends up in waterways depends on many factors, says Sousa, ranging from where the road is located to the weather rain, for example, can cause more particles to flow into the environment. Research into the topic is relatively new, he notes, so estimates will improve as more work is done. But with millions of vehicles traveling the streets every day, he says, you start to have a grim idea about the amount of tire released.
Once tire particles have made it into rivers or oceans, they can have noticeable effects on marine life. John Weinstein, at the Citadel, exposed shrimp to tire particles in lab settings and found that the animals ate the particles, which also got stuck in their gills. Once ingested, particles balled up in the shrimps guts.
It doesn’t die immediately, he says. There are these chronic long-term effects that really haven’t been studied.
Can We Do Better
The tire hasnt seen a major redesign in decades, but there has recently been a bigger push to develop more sustainable options. In 2017, for instance, researchers led by the University of Minnesota found a way to produce isoprene, a key ingredient in synthetic rubber, out of natural sources such as grass, trees and corn instead of fossil fuels. Last year Goodyear unveiled a concept tire made from recycled rubber that has moss in the middle, which is designed to soak up carbon dioxide as it travels.
Still, bits of these new tires could end up in the environment as well. Reducing tire wear, the Kole study says, would likely come at the cost of other performance metrics, such as rolling resistance, a tradeoff that may prove difficult for manufacturers to accept.
I’m not aware of any new technology to address tire or road wear, says Weinstein.
But he does see other, less direct, ways of combating the problem. Road surfaces, he suggests, could be made less abrasive or more porous to either reduce or help collect tire wear particles. He also believes that theres room for better technology to capture tire particle runoff from roads. Its a route that hes currently exploring with a town near Charleston.
Overall, though, what he sees as most urgent is further research and increased scientific and public awareness.
There needs to be more studies done, he says. I don’t know if this is on a lot of people’s radar right now.

How We Found The Best Car Tires
To compare tire brands, we collected a list of the most common tire sizes for the most popular sedans, SUVs and trucks. Focusing on common tire sizes provides a better cross-section view of the brand’s offerings and prices.
Tire prices: New tires are a significant purchase, so considering the price is important. Of course, price varies according to size and performance specs, but to simplify our general comparison we looked at average prices across several sizes and styles. For example, Goodyear’s average sedan tire is about $108, but this doesn’t mean you won’t find cheaper options. With as many as six tire options for a sedan, some cost as low as $91 and some as high as $115.
We considered the MSRP when it was listed on the manufacturer’s website. However, most tire brands don’t sell tires directly from their website and usually don’t list the MSRP. In these instances, we considered the lowest price listed by any of the retailers selling the same tire. In most cases, Tire Rack had the best prices, but sometimes Amazon’s or Walmart’s prices were the lowest.

How Tires Support A Car
You may have wondered how a car tire with 30 pounds per square inch of pressure can support a car. This is an interesting question, and it is related to several other issues, such as how much force it takes to push a tire down the road and why tires get hot when you drive .
The next time you get in your car, take a close look at the tires. You will notice that they are not really round. There is a flat spot on the bottom where the tire meets the road. This flat spot is called the contact patch, as illustrated here.
If you were looking up at a car through a glass road, you could measure the size of the contact patch. You could also make a pretty good estimate of the weight of your car, if you measured the area of the contact patches of each tire, added them together and then multiplied the sum by the tire pressure.
Since there is a certain amount of pressure per square inch in the tire, say 30 psi, then you need quite a few square inches of contact patch to carry the weight of the car. If you add more weight or decrease the pressure, then you need even more square inches of contact patch, so the flat spot gets bigger.

Where Does Synthetic Rubber Come From
Synthetic rubber, like other polymers, is made from various petroleum-based monomers. The most prevalent synthetic rubber is styrene-butadiene rubbers derived from the copolymerization of styrene and 1,3-butadiene. Other synthetic rubbers include: polyisoprene, prepared by polymerization of synthetic isoprene.
Our Continental Tire Innovations Meet The Main Challenges Posed By Electric Vehicles In Three Ways:
- Tires for electric vehicles carry a heavier load and have to withstand high instant torque, leading to higher tire wear, so we need tires with stronger constructions and more robust rubber compounds.
- Greater mass and increased inertia means longer braking distance, so we place a special emphasis on optimal grip.
- With high instant torque, increased weight, the demand for a long range and lower emissions comes an even greater need for minimal rolling resistance, so tires for electric cars offer a smoother, more energy-efficient and low-impact ride.

Stage : Building The Tire
Now, the tire building can begin. The various semi-finished products come together on the tire building machine and are assembled into what is known as a green tire. This is done in two stages: the casing, and the tread/belt assembly. This green tire is then sprayed with a special fluid to prepare it for vulcanization.
Stage : Quality Ingredients To Make Essential Compounds
Various branches of industry supply the tire manufacturing industry with raw materials, which are used to create the necessary compounds.
Steel. The steel industry supplies high-strength steel. This serves as the starting material for the manufacture of steel belts and of bead cores .
Chemicals. The chemical industry is a major tire ingredient supplier. In particular, synthetic rubber and materials used to reduce wear, increase grip, and extend the life of a tire.
Natural rubber. Rubber is extracted from special trees grown in large plantations. The milky fluid that flows out coagulates when acid is added to it. It is then cleaned with water and pressed into solid bales for easier transportation and storage.
Bales of natural and synthetic rubber are sectioned, cut into portions, weighed, and mixed with other ingredients according to precise recipes. Up to twelve different rubber compounds are used in modern passenger car tires.
Textiles. The textile industry supplies base materials for the manufacture of cords that serve as reinforcement in tires.

Other Tire Composition Elements
In addition to rubber, other elements are added to the composition during the manufacture of tires. They are necessary to improve the strength properties of the product and change its technical characteristics. Manufacturers add the following ingredients to the composition:
The mass fraction of components in products from different manufacturers is different. When selecting tires, their characteristics are taken into account.
Materials For Quiet Comfort
ContiSilent is a noise-reducing technology developed by Continental. It reduces interior noise on all road surfaces. How? ContiSilent tyres feature a polyurethane foam absorber attached to the inner surface of the tread area with an adhesive. Regardless of the temperature, the structure of the foam stays intact. Even at high speeds, the ContiSilent absorber reduces road noises inside the vehicle by up to 9 dB.

How Much Oil Does It Take To Make One Car Tire
Have you ever wondered how a car tire is made? The main ingredient, as youre likely well aware of, is rubber. In order to make rubber, however, you need oil. And in order to turn rubber and a tires other ingredients into a functional tire, you also need oil. Noting this, just how much oil does it take to create a single car tire? According to the Rubber Manufacturers Association , it takes about seven gallons of oil to create a standard car tire. The RMA states that about five gallons of oil are used as the feedstock, while another two gallons are used in the tire manufacturing process itself.
To get a better idea of why so much oil is needed to create a single car tire, you first need to understand the tire-making process.
For starters, tires are actually created from more than 200 ingredients. However, all of these ingredients can be broken down into five main categories: synthetic rubber, natural rubber, carbon black/silica, reinforcement cables and chemical agents. Many of these ingredients are then processed together in large mixers, eventually creating a black-colored rubber compound that can be milled after it is cooled.
Safety Wet Road Grip Example
To understand the role of the tire tread on wet roads, it’s useful to think of a water pump. The more channels in your tire’s tread, the better it pumps water away from the tire and the road. Remarkably, it can displace water in just a few milliseconds. A 195/65R15 tire, for instance, can displace almost 3.96 gallons of water per second.
Design elements that impact wet grip:
- Groove ratio: The more/larger grooves a tire has, the better the tire pumps out water.
- Shape and layout: The shape of the tread patterns contributes to how quickly water is drained.
- Sipes: These are thin slits in the rubber surface of the tread. They improve traction in wet or icy conditions. Acting like windshield wipers, sipes help the edges and grooves of a tire to drain away water.

Benefits And The Importance Of Having Good Car Tires
Cars are complex machines made of different parts that work together in conjunction with one another. Every part of your car has a purpose they serve and are all important as the vehicle wont be able to function without them. However, one area of the car that often gets neglected and forgetter is the tires.
Good quality car tires from shops such as Purnell Tyres come with several benefits such as an improvement in your fuel economy, better driving and handling and most importantly the overall safety of you and your passengers.
Here in this article, lets explore the benefits of having good quality tires and their importance.
The Importance of Good Car Tires
The main reason why it is important to have car tires to be well-maintained is the fact that they are the first safety net you have if you are out on the road. While working seatbelts and airbags are just as important and contribute a lot to car safety, having good and properly maintained car tires is just as important because they are the ones responsible for keeping you on the road and preventing the vehicle from getting damaged when you are on road.
Getting yourself a set of good car tires is important because they help minimize any wear and tear on your vehicle while also making the trip more pleasant for the driver and their passengers. This is especially important for passengers who have motion sickness or other similar ailments as they can make the car ride more bearable for them.
- Improved Safety and Performance
Wont My Tread Run Out Long Before My Tires Expire
Most likely. Tire tread wear associated with typical driving and use will probably expire your tires long before they expire due to age.
Exceptions include vehicles that are used only occasionally, such as classic or show cars. And dont forget spare tires, which are often not replaced over the lifetime of the vehicle. Under usual spare tire storage conditions , these unused tires may still be mounted in emergency circumstances some years past usual tire life. However, particularly if your vehicle mounts its spare tire on the exterior of the vehicle, its a good idea to check on condition at least once per year.
