Bridgestone Tyre Technology

   What it is?  Benefits
rft RFT = Run Flat Tyre
RFT tyres feature reinforced sidewalls to support the vehicles' weight even if punctured.

No roadside tyre change; continue driving until reaching a safe place to stop.
Improved comfort and safety.
 3dbldsipes 3 dimensional sipe design for improved dry handling and high level winter performances. Improved handling
Improved wet/winter performance
3dblock Supports block stiffness and therefore increases snow penetration performance of each block. Increased traction on snow.
asymmet The outside of the pattern design is different to the inside. An optimum design to balance both dry and wet performance with big and stiff blocks on the outside for dry and wide channels for wet (water drainage) on the inside. Performance for dry and wet surfaces.
clshrib Reinforced tie bar rib design with rounded block edges, giving smoother contact with the road surface and avoiding excessive "toe and shoulder" edge wear. Reduces noise.
Increased comfort.
Reduces tyre wear.
convex Reduces the likelihood of "heel and toe" wear through even force distribution in the tread blocks. Longer wear life.
Reduces the need to turn tyres to even wear.
Quiet running.
duallaytrd Made up of a hybrid tread structure with two kinds of rubber in the tread. Mounding under tread blocks results in higher grip rubber underneath being exposed as tyre wear progresses. Minimizes the effects of wear.
More consistent wet braking and handling throughout the tyre life.
Prevents noise increases associated with tyre wear.
dualsipe Improves wet/winter performance, as well as reducing stone retention. Improves wet/winter performance.
Reduced stone retention.
Excellent handling
Improved casing value
edgeprsim Simulation method to more efficiently design the sipe layout and distribution. Improved tyre design resulting in improved performance.
erd Reduces the likelihood of river wear and other wear types found on the tyres' inner ribs. Improved wear life through reduced irregular wear.
ffb 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
groove Flexible partitions in the tyre's grooves that dampen the noise produced by air bumping.
 		 Reduces noise
Evironmentally friendly
Increases driver comfort
Meets most stringent noise regulation standards
hes Originally developed by N.A.S.A., Bridgestone has adapted Hydro Evacuation Surface(H.E.S.) technology to reduce the flow resistance of water along groove walls, giving smoother and more efficient water drainage. Improved water drainage
Improved stability
hisipedens Increased number of sipes in tyre pattern. Maximizes grip without sacrificing block rigidity. Improved all-round winter performance.
Increased grip in snow and icy conditions.
irregstudlns Ensure maximum performance of each single stud on ice surfaces and hard packed snow. Improves winter tyre performance
llcarbon Long Link Carbon®:
An advanced form of carbon black. It is an improved reinforcing material that increases the wear resistance and reduces the energy loss of rubber, producing a stronger tire		 Extends tyre life
Increased resistance to cracking, chipping, tearing and excessive wear.
multicell A highly advanced and unique foam rubber based compound with high porosity. High water absorption and increased edge effect to provide excellent grip even on ice.
noise Technology applied during development to achieve the lowest possible noise emission by optimization of tread pattern design. Reduces tyre noise.
obead O-Bead is a bead rubber shape, noticeably convex at the bead heel. It improves the roundness of tyre and wheel assembly and enhances straight-line performance. By ensuring a more precise and even fit of the tyre to the rim, O-Bead provides improvements in handling, ride comfort and wear uniformity.
rbead R-Bead reduces stress in the bead area, therefore enhancing casing durability. Longer casing life
Higher casing value.
riblet Circumferential micro-grooves on the tread surface of multicell compound tyres when new. Absorbs film of water on ice surfaces for improved grip when the tyre is new and before multicell pores are exposed.
rimgd Raised rubber ridge encircling the lower sidewall above the rim-fit line. Provides protection against kerbing damage for both the tyre and the rim, and enhances the tyre's appearance.
sidegd Protects casing against sidewall damage from kerbs and other road hazards. Improved casing life expectancy.
silica Innovative reinforcing material in the tread compound, used wholly or partially as a substitute for carbon black. Improves grip and road holding, especially in wet or low temperature conditions.
Reduces energy loss from the tread compound, thus reducing rolling resistance.
snowsf-sim Pattern designed by utilizing Snow Share Force Simulation. Optimizes snow performance without sacrificing other performances.
snowsim Simulation software optimizes the pattern design. Maximum possible snow performance.
sqshoulder Reduce I/W and stable cornering behaviour. Longer tyre life, improved driver comfort.
stoneeject Ejects stones from the ribs. Reduction in stone drifting
Improved casing value
studholeshape Preshaped stud hole for better stud retention and longer life time. More even stud protrusion level during tyres life cycle.
super-ep A new improved compound additive which restrains the rubber from hardening. More consistent wet performance.
superslant Tread pattern grooves travel from the tread centre to the shoulder at a high angle, usually replacing circumferential grooves. More efficient water clearance to the side and rear, improving resistance to aqua-planing. Better contact pressure distribution improves wet and dry handling.
unidir Tread pattern design delivers optimum performance during forward rotation. Expels water more rapidly, reducing aqua-planing risk. Optimised for maximum performance in both wet and dry conditions.
vds Connector bridge between separate "blocks" in a rib type pattern. Makes the rib more solid with a maximum of traction. High traction for improved wet performance, especially during braking.
Solid ribs means a high level of handling performance.
vps Reduces the noise generated by regular pattern spacing.
Noise level is reduced by spreading out the frequency range.		 Nois level is reduced both externally and internally.
Comfort improved especially in a bus.
wavedbelt Circumferencial belt stops carcass growth in use and therefore reduces the amount of irregular wear. Reduction of irregular wear means prolonged tyre life and so a better cost/km.
zigzag Tread blocks with zig-zag shaped siping. Increased edge effect for improved grip on snow and ice surfaces.
 wavedbelt Increases durability. Higher loads and increases retreadability..
 Flat Wider Belt Further reduction of stress and strain at the belt edges. Solves irregular wear issues in low profile tyres.
 Low Energy Patter  Better control of the block movements. Increased mileage. Reduced fuel consumption.
 NanoProtech Reduces energy loss in the top compound during rotation. Reduced fuel consumption. Similar durability and abrasion as previous compound.
 Slim Bead Reduced bead filler volume and tyre weight (~1,5 Kg) without compromising the tyre durability. Fuel savings.
