In order to bond all the various parts together, the not
done product needs to be vulcanized. This involves jogging the tyres
through a curing machine which bonds all the different parts together as
well as mould all the markings & traction patterns on to the
surfaces.
Most modern automobile tyres are radial tyres. This means the cords run perpendicular to the tyres' treads.
To
work out the size of your automobile tyres' footprint, you need to know
that the area is about equal to the car's weight divided by the tyre
pressure. For a 2-tonne automobile, that means the footprint of each
tyre is about 7 inches wide by four.75 inches long. Not giant at all,
& keep in mind, while the brakes work to cease the wheels turning,
it is the friction between the tyres' footprint & the road that will
actually cease your automobile moving.
Aquaplaning
occurs when the tyre's treads cannot disperse the water quickly to
maintain a grip on the road. The vehicle therefore skids along the
surface of the water, giving you small control over the direction the
automobile is going.
Over-inflating a tyre with tire inflators
is as dangerous as under-inflating it. You finish up with a smaller
contact patch between the rubber & the road, giving you less control
of the automobile.
Under-inflating automobile tyres
bend their structure out of shape & will cause them to wear
unevenly, & faster than they ought to. It also generates more heat,
increasing the risk of a blow out.
Michelin have been
working on a used invention - the airless tyre, also called a 'tweel'
as it combines the tyre & the wheel in to.
