No less interesting laboratory studies that determine the change shape and area of the contact patch while moving at different speeds. For resistance to hydroplaning tires greatly affects the residual tread depth. For this reason, self-respecting manufacturers are testing the new tires, so and worn with a 40-60% tread. Drawer pulls often says this. Maximum mileage or tire wear. Mileage tires, primarily depends on the conditions of the tire: the nature and style of driving, the state of elements of the suspension vehicle (Shock absorbers, bearings, hubs, ball joints), correct wheel alignment (the alignment), road surface and, of course, the tire pressure. The deterioration of any of these parameters drastically reduces the possibility of mileage bus. In terms of tire technology - we're talking about durability and the wear rate of the tread.

This parameter directly determines the number of kilometers of your tires to the maximum wear, all else being equal conditions of the tire. Parameters affecting the bus iznososostoykost outdoor tread, the more open tread, the less rubber in the contact area and, therefore, more specific pressure and speed wear, the rubber in the tread (the presence of special additives), the design of the tire carcass, allowing most effectively stabilize the contact form in motion. Paradoxically, - for passenger cars initial depth of the tread, in the end, does not affect the durability or the maximum mileage tires. The deeper the tread, the greater its amplitude deformations, and thus heat, which ultimately increases rate of tread wear. So do not 'fooled' the tires with deep tread, expecting them to more efficient investment. Such 'technical solution' often guilty little known tire manufacturers from near and far Asia. Rolling resistance. In an era of global environmental crisis and price hike of fuel - all tire manufactures pay more attention to the impact of tires on fuel consumption.

A well-chosen tires can save you up to 5% fuel. Rolling resistance is directly affected by carcass construction, tread rubber composition, which determines its softness, hardness compounds of the tread blocks. This option is most difficult to define 'the eye and touch', not with the objective test results, so the leading tire manufacturers often specify the marking of their tires, tires that data belong to the class 'cost'. The 'E', 'Economy'', Fuel saving ... But do not forget that the pressure drop already below the recommended 10-15% negate all possible savings in fuel consumption.
