Tread pattern design
which delivers optimum performance during forward rotation. |
Helps expel water more rapidly, reducing the risk of
aquaplaning ; allows tread pattern design to be optimised for maximum performance in both
wet & dry conditions. |
|
Innovative reinforcing
material in the tread compound, used wholly or partially as a substitute for carbon black.
|
Improves grip and roadholding, especially in wet or
low temperature conditions. Silica also significantly reduces energy loss from the tread
compound, thus reducing rolling resistance. |
|
A new shape and
construction method for the bead coil. The bead coil is formed from a single wire by
spiral winding, and has a diamond shaped cross-section as opposed to the conventional
rectangular shape. |
By significantly increasing the torsional or twisting
stiffness of the bead coil, a more uniform contact patch is realised especially when
cornering, improving handling and grip in all conditions. In addition, the mono-spiral
construction gives improved uniformity to the tyre. |
|
Tread pattern grooves
which travel from tread centre to shoulder at a high angle, usually replacing
circumferential grooves. |
More efficient water clearance to the side and rear,
improving resistance to aquaplaning. Better contact pressure distribution improves wet and
dry handling. |
|
Block edges are curved
downwards towards the base of the grooves. |
These curved tread block edges enable the tyre to
displace water more smoothly and efficiently, resulting in improved wet braking and
reduced risk of hydroplaning. |
|
An improved tread block
design which varies the angle of the block edges in accordance with their size. |
More even block stiffness means more uniform contact
pressure as the tyre rotates, resulting in a smoother ride. |
|
Raised rubber ridge
encircling the lower sidewall above the rim-fit line. |
Provides protection against kerbing damage for both
the tyre and the rim, also enhances tyre appearance. |
|
A spiral winding method
of applying the nylon overlays which constrain the belt package under the tread. |
Improved high speed handling, durability and
uniformity. |
|
Narrow slots in the tread
which increase in width as the tyre wears, due to their 'keyhole' shape. |
Keyhole sipes help maintain wet performance as the
tyre nears the end of its life. |
|
Specially designed soft
rubber between tread rubber and belt. |
Minimizes unpleasant shocks from the road surfaces
and maintains a smooth ride comfort. |
|
A highly advanced and
unique foam rubber based compound. |
The high porosity of multicell compound enables water
absorption and increased edge effect to provide excellent grip even on ice. |
|
Tread blocks with
zig-zag shaped siping. |
Increased 'edge effect' for improved grip on snow and
ice surfaces. |
|
Variable length zig-zag
siping of tread blocks. |
Optimum balance of 'edge effect' for grip on snow and
ice without compromising tread block rigidity. |
|
Circumferential,
micro-grooves on the tread surface of multicell compound tyres when new. |
Absorbs film of water on ice surface for improved
grip when the tyre is new and before multicell pores are exposed. |
