Summer tires influence the driving abilities
The turn of the seasonal change of tires had come again. Summer tires also have their own classification. Tire thickness, tire tread, and its width are playing a significant role in the driving ability of the car. Conditionally, there are three types of summer tires: universal, highway, out of road. Also, it is necessary to store the tires properly, we wrote about it here.
When choosing a tire, pay attention to the speed index (letter of the alphabet) and the load index (the numerical index under which the weight (kg) is encrypted, the tire load index) - marking on the tire. The manufacturer of the car indicates the dimension of the recommended tires. Width and height are denoted by a slash (XXX/YY).
How do all of the factors influence the driving abilities?
To choose a wide or narrow cross-section of the tire is a matter of personal preference of the driver and his driving style. In this regard, the views of car owners often differ. Wide tires are more often set by those who like to drive fast, narrow are set by those who have measured car. However, the noise level of a wide-profile tire is higher than that of a narrow one. In this case, the indicator can be balanced by the softness of the tire (but wear resistance suffers). More important to pay attention to the combination of the tire cross-section with the type of tread.
Tread Ply (protector) Types
Cross or Bias Ply
This type of tread provides a better rate of depreciation with the inconspicuous road surface, as well as increase the level of noiselessness. Due to this, the ride will be comfortable. Despite the fact that some (as an exception) models of tires with symmetrically undirected tread design have a good speed index. It does not matter which side to install on the alloy wheel that the cost of such tires in comparison with others, usually the minimal. However, there are the disadvantages of this type of tread - poor directional stability, increased braking distance on wet asphalt, poor handling at high speed and therefore low-speed index (most manufacturers). These are all the disadvantages of this type of tread.
Radial ply type
Asymmetrical non-directional design of the protector. External (outside) and internal (inner) sides have differences (asymmetry) in the picture figure. This protector is more resistant to aggressive driving style (sharp turns and braking) and high load. They predominate on sports cars, and therefore have a high-speed index, handling, reliability, and also have noiselessness. The tyre on the vehicle must be fitted with a specific inner and outer marking. If we talk about the shortcomings is the high cost and rapid wear, these tires are not suitable the off-road quality handling and reliability drops dramatically when driving on a bad road surface.
Belted bias ply type
The peculiarity is based on the direction of the wheel’s rotation. These tyres are marked with rotation indicating the direction of rotation. This type of tread has a high level of resistance to hydroplaning. Especially this tire protector is suitable for SUVs and rear-wheel drive cars, including sports cars. Belted bias plys are good handling at medium speeds, but at high reliability falls. High safety in rain and slush. However, it has high noise levels. Complex fixation (matters what tyre on what awn be put).
Belted radial ply type
Asymmetric directional tire tread pattern, one of the rarest one. Require to consider when installing on the car, not only the position but also the direction of rotation of the tire. Widely applicable in Motorsport and expensive hypercar. They are suitable only for high-quality roads, wear out quickly when unrighteous installation, the most expensive in the segment, justify their characteristics only at high speed. Therefore, such a protector has a maximum speed index, maximum control, and course stability, effectively counteract hydroplaning, have improved braking properties.
For passenger cars use a load index of rubber from 60 to 125, or in other words, from 250 kg up to 1650 kg. In this framework includes both a small car and large SUVs.
