If you can afford a big bus with a speed rating (they are 10-15% more expensive) – I would recommend this option active drivers drive. However, do not skimp on the index of the rate, lowering it below the recommended (especially when buying cheap winter tires) – known as the 'better safe than sorry …'. Summer features. This is a series of consumer quality tires that are more fully realized when used in tire temperatures above + 7 C. Adhesion to dry. This indicator measures the brake or coupling properties of the tires when driving on dry hard surface. Influence on this parameter: the mixture of rubber, the contact area of rubber on the road (Closed design), the stability of the contact form (depending on the design of tires).
The best way to evaluate this option – to study the results of objective tests of braking tires, published by reputable journals. Traction in the wet. Determined by the efficiency of braking in the wet solid surfaces. Depends on the presence in the tread compound of the special additives that additional edge strength (blades), the stability of the form contact patch. Objective tests – the best way to evaluate this option.
Manageability – this property is set to follow the bus driver of the trajectory of the car, informative steering reactions. At this setting will affect form the tread pattern rigidity of its central area and the shoulder elements of rubber. For motion in cornering stability is particularly important form of the contact, depending on the design of the tire carcass and the presence of reinforcing layers-breakers.Tags: auto and moto, Repair and Parts
