Do you like such tuning? Looks incredible and amazing, isn’t it? Creative scientists don’t stop to impress us with their inventions. Computer modding in a form of automobile wheels is not a surprise nowadays. It is one more specimen of a good quality, which looks rather cool and extraodinary.
A computer, called Porsche SLI-Machine, has a form of Porsche Cayeene wheel and reflects the imagination of modern computer designers. Inside the chrome rim of the wheel there are two Nvidia SLI video cards and a special liquid-cooled system.
This computer made from an automobile wheel was even exhibited at the modding SLI-Machine competition and became the winner in the first part of it.
3 Ways to Feel Safe in Your Car

The time when you start thinking about the safety of your car will come earlier or later. Some people such as politicians and businessmen are worried about their own safety and the safety of their automobile. Other people simply don’t want to lose their time and feel frustrated when they have to change a flat tire in the rain, at night or on a motorway, being late for an important meeting.
Now a solution how to feel safe in your own car has appeared due to the technology of run-flat tires. Of course, such tires are used in luxirious cars or in sportcars, but at first this technology was used in a very small car - Mini 1275GT in 1974.
To describe how this system works we shold emphasize the main essence of run-flat tires: when the tire is punctured, the tireair under a high pressure is blown out and the tire becomes hollow. What is more surprising, the driver doesn’t feel any uncomfort what can’t be said about simple flat tires.
There are some types of run-flat tires. Self-supporting run-flat tires have thick stiff side-walls, which don’t allow the rubber to sag and maintain a normal work of wheels even in cases of a sudden fall of pressure. Exactly this type of magic run-flat tires was firstly used in Mini. As a rule such tires allow a car to drive for 50 miles at around 50 miles per hour. It may become impossible to repair it, if it has a puncture in the sidewall or at the edge of the tread.
Self-sealing run-flat tires have an extra lining inside the tire. When your tire is punctured, this extra-lining will provide a seal around a sharp object and prevent it from causing damage to the whole tire.
Auxiliary-supported run-flat tires provide run-flat capability on the weel by minimizing the task which has to be fullfilled by the tire. So this technology improves the riding qualities of your car.
Ecological Tires By Michelin

With Michelin tires You can spare gallons of fuel annually thus contributing to the protection of the environment!
How it all happens? During the ride the tire deforms to “hold” the road better thus ensuring comfort and confident steering. But the deformation leads to the tire’s heating what results in the loss of the part of the engine power. As a result every fifth full fuel tank or 20% of the total fuel consumption are spent on the struggling with the event that is called “rolling resistance”. Obviously, it cannot but cause negative consequences for the environment due to the increased amount of exhaust gases that create “greenhouse effect”.
So, major efforts of tire manufacturers are to be aimed, on the one hand, at the reducing rolling resistance and, on the other hand, at the retaining of the performance of the tire. The Michelin company draws special attention to the development of technologies that could save the problem.
Already in 1946 the Michelin company succeeded having reduced rolling resistance by 30% thanks to the production of the tires with the radial carcass. But the real revolution on the passenger tire market took place in 1992 when the Michelin company managed to add silica (silicone dioxide) to the rubber compound. Thanks to the new compound the company succeeded in reducing energy losses that occur during the deformation thus having increased the fuel efficiency of its tires.
As a result the driver was able to spare up to 3% of his fuel expenses. If all the passenger cars in the US had been equipped with “green” tires the saving would have amounted to $ 5mln. The amount of exhaust gas discharge in this case would have been reduced by 7,5 million tons what is equal to the amount of harmful substances absorbed annually by nearly 300 million trees.
Why Are Japanese Used Tires So Good?

Numerous tire specialists and regular drivers all over the world note that the majority of Japanese used tires are of extremely high quality. There are a few reasons for that:
1. When buying a new car in Japan its cost also includes free maintenance for 2-3 years. Such maintenance includes not only the changing of oil and other operational liquids, testing and adjustment of all major components but also the changing of tires regardless of their condition. As the majority of the Japanese have two or three cars and their annual mileage rarely exceeds 7 thousand miles the condition of such tires is very good.
2. Japan is a highly-developed country with a high level of consumption and well-developed system of goods promotion. New models of tires appear every 2-3 years and many Japanese get convinced by the commercials that proclaims the supremacy of the new models. So they change the tires even after driving a few thousand miles on them.
3. In Japan when mounting winter or summer tires many firms accept the used tires to stimulate the demand. One should just pay the difference in price between the new and the used tires.
All these reasons lead to the emergence of a great number of quality tires with little wear. Such tires are exported to Australia, New Zealand, China, Russia etc. Many Japanese also buy used tires for their cars.
The advantage of the Japanese used tires can also be explained by the high requirements in respect of the quality of the goods that are sold on the domestic market.
That’s why such tires are not heavy, flexible, provide low noise level and ensure long service life.
