low - profile rezina:plusa and minuses ofit is low - profile rubber. Merits and demerits.
Today, rubber with a low profile, it is possible to describe in a word - fashionable.
For the first time, rubber with a low profile the French Shinniki of Michelin in 1937 began to use. It turned out so that city roads and cars of that time were fully not capable to use such rubber, but it found the popularity only on racing tracks. And already in 1977, the Pirelli company presented to general public the rulers low - profile P6 and P7 rubber. Since that moment rubber with a low profile began to find wide popularity of drivers and today almost each bus company can offer the low - profile models. producers recommend to
In the operation manual on the vehicle rubber with height of a profile, not lower than 70 therefore technically, the tire with a low profile that at which the ratio of height to width of a profile makes less than 70 percent is considered. There is an opinion that the less this ratio (for example 50%), the is better controllability of the vehicle. We dare to assume that it mistakenly and often, most of drivers simply will not realize all potential of such tires. In most cases it is purely esthetic moment and the choice of such rubber it is caused by the fact that the car, like abruptly looks.
the Low profile of the tire provides smaller “demolition“ and a swing of a body of the car at high-speed maneuver and therefore increases its controllability. However the reverse of the medal is that the low profile is not capable to cope with roughnesses of a relief also effectively. Return is transferred to car suspension bracket elements, increasing its wear, plus loss of smoothness of driving.
If to speak not about height, and about tire profile width, then it also influences controllability and the related feelings on a wheel. The tire profile is wider, the cruiser stability and the moment of braking of the car are better, however rotation of a wheel happens heavier and if the car is not equipped with the power steering, is broad - profile tires considerably complicate life to the driver at rotation at small speeds and the parking.
As for cargo transport, for it also let out low - profile rubber with height of a profile 60, 55 and even 50. The global manufacturers supplying with tires commercial transport have the whole lines of such models.
Pluses low - profile
rubber Low - profile tires appeared because modern cars became quicker and more powerfully. More effective brakes and the best coupling with the road are required for such car. The sizes of a brake disk are limited to the wheel rim sizes. It is simple to increase diameter of a rim without change of outer diameter of the tire it is impossible - in it there will be not enough air. Therefore after reduction of a profile there is an increase in width of a tire owing to what the spot of contact with a surface increases.
Is low - profile rubber is intended for high-speed cars. Even protector drawing at such tires often reminds that on racing cars. “Thin“ tires differ from standard not only high high-speed characteristics, but also the best coupling with the road, especially at “active“ passing of turns and bends at the expense of rather soft framework of the tire. A smaller swing, higher degree of resistance to lateral withdrawal and, as a result, the best stability and controllability of the car - here advantages of a low profile. And when braking such type of the tire is more preferable.
Minuses low - profile
rubber In - the first, short service life of the tire, especially on our roads. In - the second, it is necessary to offer comfort of driving and a resource of a suspension bracket and some details of a running gear. Regardless of composition of rubber the car will become more rigid to react to all defects of a roadbed. On potholes the wheel will amortize blow less. The profile is lower, the worse the tire fulfills
of roughness and the stronger there is a return on suspension bracket elements. Besides, wide it is low -
profile rubber publishes more noise when driving as a contact spot between the tire and the road much more, than at a standard tire.
To understand to put or not to put low - profile rubber, it is necessary to represent car service conditions accurately. If you in the majority drive about on city roads and highways, and in combination love high-speed bends, then this rubber will just approach, especially in combination with cast disks. However, if you the quiet driver, the fan of smooth, comfortable driving, and also frequent trips on country country roads - be limited to the standard height of a profile, well, or as a last resort, make a choice for golden mean. Reliability and safety are much more important than abrupt appearance and feeling of the drive in bends. Unfortunately, to puncture low - profile tires and even to break a cast disk, having got to a hole, will not make big work, and to here repair such tires out of the large city, on the route, not each point of car service will be able and it is minus too.
Finally wants to give advice: “Placing choice priorities, it is always worth paying the closest attention to safety issues and only in the last turn an esthetics and fashion. If you are not sure of the opinion, ask the qualified council professionals and attentively read the instruction to the vehicle.
