Pirelli brings new tire dimensions to the 2021 formula one season: what that means for teams when designing cars and whether racing will get better

(motorsport-total.Com) – part of the new vehicle concept for the new 2022 formula 1 season are also the 18-inch rims, which have been the subject of repeated talk for some time now. Tire manufacturer pirelli had to develop and produce a completely new product with a significantly shorter sidewall for this purpose.

And that’s what teams and drivers will probably have to get used to the most when it comes to tire behavior compared with the previous model.

First, the driver’s vision is more impaired than before. Not only the rims were increased in diameter, but also the entire tires. When mounted, the new tires are 60 millimeters larger than before. This, of course, makes it more difficult to see over it from inside the car.

In addition, visibility will be further compromised when we add the new deflector that will be mounted above it.

Aerodynamicists will also be challenged by the changes, as the lower profile tire will behave differently than the previous rubber. The dynamic behavior of the tire leads to inconsistencies that you definitely want to get under control.

In the recent past, a number of aerodynamic tricks have been used to reduce the tyre squirt to mitigate the well-known walg effect. However, with many of these features either removed or severely restricted, teams have had to find new ways to deal with the resulting change in tire stiffness and sidewall height.

Pirelli has long had the task of making the sport more entertaining. Thermal degradation has been identified as a way to create strategic differences between teams and drivers.

However, as part of the revision, the drivers had asked for this aspect to be given less prominence. You want to be able to drive more freely without fear of having to manage the tires so much during a race.

In years past, it was common to drive well below the car’s actual potential to prevent the tire from overheating and requiring an additional pit stop. All the driver had to do during a stint was stick to a lap time delta. With older tires, the car was on the road faster than with an additional pit stop and fresh tires.

If you then take into account the time lost by overtaking other cars or lapped drivers, the turtle tactic was suddenly much more attractive than the full-throttle hare tactic.

However, pirelli’s approach to the development of the new tires and the impact of the redesign of the car could change this strategy.

The stiffer tires with shorter sidewalls will feature a new design to address some of the temperature issues teams have faced at the tire shoulder. This should lead to lower management.

Hunting for performance

The teams have worked hard in the past era to address some of these issues, and have found performance reserves in numerous places – be it in the strategy for the tire cover, the design of the rims, the brake ducts or the suspension.

All of these elements will need to be redesigned for 2022. Don’t forget that the aerodynamic balance of the car will also change as a result of the switch to a more underbody-focused design.

Tires will no longer be allowed to heat up as much from 2022 zoom download

While current regulations indicate that tire ceilings will be permanently banned from 2024, the most important change from 2022 is that the maximum temperature of ceilings will be reduced from 100 to 70 degrees celsius.

This could affect how drivers drive out of the pit lane or approach the race start, as they may need to warm up the tires first instead of managing their temperature immediately.

However, the way the tires are handled may change in any case, because while many teams have increased suspension elements and used more extreme pushrod-on-upright solutions to help with various aerodynamic efforts in recent years, these have been removed along with the hydraulic solutions.

Instead, teams will return to classic spring suspension, which will naturally affect the behavior of the car and give the driver a different feedback and feel.

Switching to BBS as the sole rim supplier means that all the advantages they had in controlling heat transfer between rim and tire will also be lost. The large cooling fins seen on mercedes in recent years are no longer possible.

Larger brakes

It should also be noted that the size of the brake discs will also change in 2022. The standard diameter of 278 millimeters used since 2017 for the front and rear discs will be replaced by new dimensions.

At the front, teams can choose a disc size between 325 and 330 millimeters, while at the rear a disc diameter between 275 and 280 millimeters is permitted.

The brakes also get new dimensions zoom download

These changes obviously affect the design of the brake discs and their proximity to the larger rims, with additional design considerations also going into the brake channel design.

This could be a way for the teams to gain some small advantages over their competitors.

But even if the possibility of developing designs as complex as in the past has been drastically reduced, the transfer of heat generated during braking could still prove crucial for the temperature management of the tires.

As can be seen from the design of mclaren’s test carrier, there is the possibility of enlarging the brake drum to adapt it to the size, as would have been done in the past. However, the teams could also see the advantages of a slightly smaller drum and a larger space between it and the rim.

As anticipation builds for the 2022 season and we get to see the cars for the first time, we’ll no doubt be raving about the different aerodynamic approaches the teams have taken in light of the new rules.

but teams and drivers will hope that they have done everything right in the aspects that can influence tire performance.

Accident with the police car: Is always the private person to blame?

accident with the police car: is always the private person at fault?

Since 1880, the so-called martin horn unmistakable for care in road traffic. Because if the sound of the fanfare from a patrol car with a frequency between 360 and 630 hertz to the ear of road users, they know that a rescue or emergency vehicle is nearby. This way, an emergency lane can be formed in good time for the police or emergency services and a free passage can be guaranteed.

However, car drivers are not always able to react in time because they do not know the hear signal too late for example. In such stressful situations, an accident with the police car can be the result. In the event of such an accident, quite a few road users are uncertain about the extent to which the officers involved in the accident are held responsible can be.

If, in the event of an accident involving the police vehicle, civilians may be always the driver of the private vehicle at fault?

FAQ: accident with a police car

No, despite some special rights (e.g. B. right of way) of the police, a duty of care also applies to them. If the accident occurs, it is clarified whether these were injured.

Yes, especially if the accident was your own fault and you were not on duty during the accident.

claims are handled by the respective department or the country in which the police officer is employed.

Rights and duties during emergency response

In the event of a traffic accident with a police vehicle, the first thing to clarify is whether the vehicle was in danger car in an operation the road, the other road users must give it a to grant the right of way was.

§ 35 stvo grants among other things service vehicles of the police special rights, which exempts the officers from the rules of the stvo. The privilege of such special-law vehicles however, is always subject to the consideration of public safety.

In § 38 stvo in certain cases, the special rights vehicles are qualified by the occurrence of an right of way. If a police car is under use of blue light and martin horn on the road, it is the duty of all other road users to create a clear lane immediately.

So even though the stvo gives police vehicles certain freedoms, these do not apply without restriction. For example, an emergency driver cannot simply rely on the fact that his right of way will be observed by all other truck, motorcycle and car drivers. Rather, he must always make sure and is subject to a separate duty of care when exercising its special rights.

Accident with the police car: what is to be considered?

In the event of an accident with a police car, the decisive factor is whether the siren and blue light were switched on

In an accident with a police car, the decisive factor is whether the martin horn and blue light were switched on.

Although the police are granted specific special rights by the road traffic regulations in order to fulfill their sovereign duties, the question of guilt is decided in the event of an accident with the police car not necessarily at the expense of the other party to the accident. Because an officer is without martin horn and blue light or if you are only driving with one of the two signals, the right of way does not apply. A disregard of possible traffic regulations is then not legally legitimized.

Even if it is an emergency drive with corresponding acoustic-visual markings, the officers receive no free pass for driving maneuvers in violation of duty. Especially a duty of care applies at intersections, according to which the officer may only drive so fast that he can stop in time in the event of cross-traffic. If an accident occurs with a police car because the police officer carelessly crossed the intersection, he is fully liable because the accident was his own fault.

Diffuse tingling in the legs, signs of paralysis, pain or difficulty walking – the symptoms of polyneuropathy are varied and often difficult to classify. This is also the reason why in many cases the disease is only diagnosed at a late stage. In addition, it is a complex clinical picture with many possible causes. All of this complicates diagnosis and treatment, and often means a major break in the lives of sufferers and their families.

But what is this disease with the difficult name actually about?? In this blog post we want to give you an introduction to the topic by presenting the typical causes and symptoms.

What is polyneuropathy?

Polyneuropathy is a generic term for diseases of the peripheral nervous system. Depending on the cause, motor, sensory or autonomic nerves can be affected and lead to very different symptoms. Peripheral nerves have many important functions: they command muscles to contract, and in the skin they enable sensitive sensation of temperature and touch. Even if the spinal cord and the brain are not endangered by polyneuropathy, autonomic nerves can also be affected and thus impair vital functions such as digestion and breathing. Diabetics are particularly affected by this form of autonomic polyneuropathy. Due to the dangerous nature of the symptoms, it is particularly important to detect the disease at an early stage in order to prevent possible complications and consequential damage. The earlier the disease is detected, the easier it is to find suitable treatment methods.

Typical polyneuropathy symptoms

the symptoms of polyneuropathy vary depending on which type of nerve is damaged. as a rule, the symptoms of polyneuropathy first appear on the lower extremities. The affected person initially experiences various sensory disturbances in the feet or lower legs. The legs may feel tired quickly or there may be signs of paralysis.

The damage sensitive nerves often leads to problems in the arms and legs. The range of sensations extends from tingling to stabbing or burning pain. Since the temperature sensation often decreases as well, the risk of injury increases.

Are they motor nerves, affected, it can lead to the failure of certain muscle groups. Depending on the severity of the polyneuropathy, the symptoms range from muscle weakness or muscle cramps to paralysis.

Particularly dangerous damage to autonomic (vegetative) nerves, as they control vital organs such as the heart, lungs, gastrointestinal tract or the bladder with commands. Because of their vital function, disorders in these areas are particularly dangerous. If intestinal function is impaired, for example, diarrhea or constipation may occur. If the lungs are affected, respiratory arrest may occur.

Overview of typical symptoms of polyneuropathy:

tingling, ants, numbness or pain in arms and legs, feeling of swelling in the legs
Rapid fatigue of the legs
Coordination difficulties and walking problems
Disorders of fine motor skills
Muscle paralysis
Disturbances in bladder or bowel emptying
Sleep disturbances as a result of the above symptoms

The frequent or constant complaints together with sleep disturbances not infrequently lead to a devastating domino effect that can severely impair the overall quality of life: chronic fatigue, impaired concentration or even depression can follow.

Diabetic polyneuropathy – the most common form of polyneuropathy

People with diabetes belong to a special risk group. It is estimated that about one in three patients suffers from neuropathy. As a result of elevated blood glucose levels, the sensitive nerve fibers are the first to be damaged. Common symptoms include numbness or tingling in the legs up to severe pain. It is typical that the polyneuropathy symptoms worsen especially at night and deprive the affected person of sleep. On the other hand, diabetic polyneuropathy can also lead to reduced pain sensation, so that injuries are often not noticed. This in turn is unfavorable, as wound healing is also impaired in diabetics.

In addition, disorders of the autonomic nerves are possible, which can lead to dysphagia, nausea, bladder weakness, diarrhea or constipation.

Alcoholic polyneuropathy: polyneuropathy caused by excessive alcohol consumption

It is common knowledge that excessive alcohol consumption is unhealthy. However, it is less well known that alcohol can cause serious damage to the nerves as well as the liver. This effect is intensified by malnutrition, which is present in many alcoholics. on the one hand, they eat a diet that is too one-sided, on the other hand, the mucous membrane of the stomach is often so damaged by alcohol consumption that vitamins are no longer absorbed well. An insufficient intake of vitamin B12 is one of the main reasons why nerves are damaged. Most of the time, the symptoms first appear in the legs. Pain, sensory disturbances or muscle atrophy occur. In the worst case, alcoholics can be affected by muscle atrophy, so that they can no longer stand or walk.

Malnutrition& vitamin deficiency as a cause

Vitamin deficiency is generally considered rare in the western world, but it does affect certain groups of people. According to statistics, one in two hospital patients over the age of 75 is malnourished when they are admitted to a clinic. This is often due to chronic illnesses, physical limitations and unbalanced eating habits. A closer look shows that a combination of different factors can promote the development of malnutrition. Last but not least, functional limitations of organs lead to the fact that the absorption of nutrients is impaired. Depending on which B vitamin the body lacks, different symptoms occur. Possible effects include polyneuropathy in the legs, paralysis of the eye muscles or hearing loss.

toxic polyneuropathy

Nerve damage due to poisoning is considered a rare cause of disease in the literature, accounting for only 1-2% of cases. However, neurologists have noticed that more and more patients are developing signs of polyneuropathy after coming into contact with toxic substances.

Since the symptoms are usually diffuse and difficult to classify, the connection with toxic agents often remains undetected. Nevertheless, experts believe that more importance should be attached to this form of polyneuropathy in the future – also in view of the increasing pollution in the environment.

Genetic predisposition& polyneuropathy as a result of disease

In addition to the cases mentioned above, there are many other causes for the outbreak of the disease.

Polyneuropathy also occurs as a consequence of various diseases. With a meningitis a severe course of the disease can even lead to paralysis and polyneuropathies.

also infections, first and foremost borreliosis, can bring about a polyneuropathy.

Rather rare, however, is the guillain-barre syndrome, an immunologically caused disease.

Also worth mentioning genetic polyneuropathy, which accounts for 5% of all cases.
