Automakers regularly update newcar models in terms of travel speed and ride comfort, from which it is quite logical to make adjustments to the design of the wheels. The development and fairly widespread use of low-profile rubber was one of such innovations. It not only changed the design of vehicles, but also had a positive impact on driving performance.
Low profile rubber has been developedFrench company Michelin in 1937, specifically for use in racing cars. However, the experience of their use on ordinary roads was so negative that the company Pirelli again decided to return to a similar idea in 1978.
Low profile tires can be distinguished from normallabeling. For example, 225/55 R16, in which, respectively, the first number indicates the width of the tire in millimeters, the second - the ratio of the width and height of the profile in percent, the third - the type of rubber: standard, low profile or sporty. The ratio of the cross-section of rubber to its width in low-profile rubber should not exceed 80%, i.e. 0.8.
Despite the fact that a few decades ago toThe low profile rubber category included tires of no more than 70 series; today, only tires with a series not exceeding 55 are considered as tires. The index of low-profile tires for passenger cars gradually decreases with the development of technology: car owners reject such tires when choosing such tires usually from series 55 in the direction of its reduction. The main difference of such rubber from other types of tires is the speed index: H and V - 210 km / h and 240 km / h, respectively. For conventional rubber, only one speed index is characteristic - T, corresponding to 190 km / h.
Практически все современные марки и модели резины can be attributed to low-profile, since the tire width almost always exceeds the cord height, and the most common marking is from 50 to 75. For example, R18 255/100 tires, which are very effective in off-road conditions and completely useless, are installed on cars city line.
Низкопрофильные шины отличаются большей stiffness with a small height of the wheel, which ensures the stability of the car when cornering, fuel economy and better handling. In most cases, low-profile tires are equipped with brake discs of increased diameter, which improves braking performance and reduces the braking distance of the car, thereby increasing the level of safety. Despite the fact that the reduction of the profile allowed to achieve such advantages, it entailed certain disadvantages that are typical for this type of tires.
Car owners in their reviews based on operating experience of tires, note the pros and cons of low-profile rubber. We list the main ones that drivers bring.
Typical for low-profile rubber speedThe parameters turn into flaws, especially noticeable when driving on a low-quality highway. This is manifested in the rapid wear of the discs and the damage caused by the running vehicle.
Car owners in the reviews of low-profile tires note the following disadvantages:
При ответе на вопрос о том, какая низкопрофильная rubber is better, it is necessary to consider the operating conditions of the car. Ideally, the vehicle should be used only on a flat track with the ability to travel at maximum speed. In addition, when choosing a low-profile rubber, the recommendations of automakers regarding the brands and models of tires that are suitable for installation on a particular car are taken into account.
When choosing a low profile rubber are taken into accountrecommendations not only of the auto concern, but also of the manufacturer of the rubber itself: the quality and safety of tires should not cause any complaints, otherwise there is a likelihood of loss of control on the road and the risk of accidents.
Car owners and experts identify several brands and models of low-profile tires that are of high quality and popular with motorists.
American summer low-profile tires have the following advantages:
The only disadvantage of this rubber brand is a high level of noise while driving on the highway.
Italian winter low profile tires are installed mainly on high-speed cars equipped with high power engines. The main advantages of tires are as follows:
The lack of rubber - it is not suitable for use in harsh winter conditions.
American low profile tires designed for SUVs and crossovers have the following advantages:
The only drawback is susceptibility to damage.
Низкопрофильная резина - индивидуальный выбор every car owner who weighed all the positive and negative sides of this type of tire. On the one hand, a low profile guarantees good car handling and fuel economy, on the other hand, it requires frequent repairs of disks and suspension. If this rubber is installed, it is necessary to comply with certain requirements of operation and to adhere to careful driving style. Low profile tires are not recommended for novice drivers, because in the absence of proper driving experience, the risk of loss of control and emergency situations on the highway, as well as rapid wear of the tires, increases, as a rule, they do not withstand a single season of active use.
