Шина - це значно більше, ніж гумове кільце, наповнене повітрям. Це складна конструкція з різними можливими формами, запроектована для вирішення багатьох завдань. У цьому розділі ми прагнемо познайомити Вас з різними типами шин на ринку і перевагами кожної з них.
There are two key areas where one type is distinguishable from another – the rubber compound and the tread pattern. These, in turn, are determined by the environment and conditions where the tire is in use. As long as the right tire technology is applied, you can rest assured that the wheels of your car or truck will have superior handling and traction.
Summer tires have a dedicated rubber compound that delivers excellent grip and handling on both dry and wet roads in warmer conditions. They also have reduced rolling resistance and therefore provide greater fuel efficiency and generate less road noise.
The tread pattern on a summer tire is more streamlined than a winter tire, with fewer grooves for water clearance, maximizing the contact patch with the road. Consequently, the vehicle has superior traction and braking during dry summer months.
However, these same characteristics – the unique rubber compound and simple tread design – make summer tires unsuitable for winter driving conditions. When the temperature drops below 45 degrees Fahrenheit (7 degrees Celsius), the compound becomes hard and brittle, and the tread design can’t adequately handle snow or ice.
Winter tires provide outstanding grip on road surfaces covered with snow and ice, as well as wet roads in cold conditions.
The tread compound of a winter tire contains more natural rubber, so it doesn’t harden when the temperature drops below 45 degrees Fahrenheit (7 degrees Celsius). Instead, it stays flexible and limber in cold climates to reduce the stopping distance when braking.
The tread design has deeper blocks that will dig into snow and ice to provide more grip. The winter tire also has a lot of sipes, which are excellent for clearing water and slush from the path of the car and mitigating the risk of hydroplaning.
Winter tires shouldn't be used for the summer season, however. The compound is far too soft for dry asphalt, meaning it will wear out quicker. Moreover, the increased rolling resistance will lead to higher fuel consumption and road buzz.
An all-season tire combines characteristics of both summer and winter tires, offering a hybrid solution with the benefits of both. For drivers, living in regions with mild winter conditions (temperatures rarely drop below freezing), all-season tires can be an alternative. Continental all-season tires offer safety and premium performance. In addition, drivers can save money and time, and reduce the effort required for seasonal tire changes . But always remember that summer and winter tires are specifically tailored to the relevant conditions.
If you are unsure about the right tire choice, please contact your local dealer for personal advice.
Run-flat tires are one of the greatest inventions in the automotive industry since the advent of the pneumatic tire or the transition from bias-ply to radial tires. Why is it so revolutionary? In the event of a puncture, or a sudden drop in inflation pressure, a run-flat tire will remain fully operational until the driver can make it home or to the nearest garage safely.
The functionality of a run-flat tire is provided by strong and thick reinforced sidewalls so that they can be driven on temporarily after a puncture. In general, you should be able to travel up to 80 kilometers (50 miles) on a punctured run-flat tire. But keep in mind that they’re not repairable, and you must replace it with a new tire as soon as possible.
4x4 truck tires feature a more widely spaced tread design than conventional car tires, chiefly a larger tread block and deeper tire grooves. Standard tires perform poorly on surfaces like muddy ground because the tread quickly fills with mud and the wheel begins to spin uselessly, digging the tire deeper and deeper into a hole. By comparison, 4x4 truck tires have better traction on tough terrains like mud, grass, and snow without the tread area becoming clogged.
