TIRES
the primary purpose of tires is to provide traction. Tires
also help the suspension absorb road shocks, but this is a side
benefit. They must perform under a variety of condions.
The road might be wet or dry or paved with as-phalt, concrete, or gravel, or there might be no road at all.
The car might be traveling slowly on a straight road,or
moving quickly through curves or over hills. All of these
conditions call for special requirements that must be present,
at least to some degree, in all tires.
In addition to providing good traction, tires are also
designed to carry the weight of the vehicle, to withstand
side thrust over varying speeds and conditions, and to
transfer braking and driving torque to the road. As a tire
rolls on the road, friction is created between the tire and
road. This friction gives the tire its traction. Although good
traction is desirable, it must be limited. Too much traction
means there is much friction. Too much friction means
there is a lot of rolling resistance. Rolling resistance wastes
engine power and fuel; therefore, it must be kept to a minimal level.this dilemma is a major concern in the design of today's tires.
