A pattern of band of tread of open shoulder is a design of tyre of drive in the that the side grooves se extend from the centro of the surface of the band up to the edges exteriores of the tyre. A difference of a design of closed shoulder that presenta a rib continua a along each side of the band, the tyres of open shoulder have blocks distintos and separados a all the width of the contact patch. This creates a higher ratio of empty — the percentage of the surface of the band ocupado by grooves instead of rubber — which changes fundamentally how the tyre interactúa with the surface of the road.
The features definitorias of a pattern of open shoulder include side grooves wide that channel agua, mud and mud outside the contact patch; edges of bloque aggressive that muerden surfaces sueltas for generar drive; and a geometry autolimpiante that expels the debris and avoids that the material se packaging in the band. These features do that the drive tyres of open shoulder are the choice preferida for any application where the conditions of the surface are variables, impredecibles or consistentmente demanding.
From a perspectiva of engineering, the pattern of open shoulder funciona maximising the number of biting edges that contactan the surface of the road. Every bloque individual actúa as a elemento of grip separado, and the channels abiertos between blocks allow that the tyre se adapte a surfaces uneven. When the tyre wheel by mud, gravel or water estanevery, the grooves abiertos provide roads of escape for the material desplazado, maintaining the contact between the rubber and the road. That is why the tyres of open shoulder deliver a drive superior in conditions where the designs of closed shoulder would have dificultades with the hidroplaneo, the packaging of mud or the slipping superficial.
The grooves se extend of edge a edge a it width complete of the band, channelling water and debris outside the contact patch for maximum drive in wet.
Blocks of shoulder separados create more biting edges that grip surfaces sueltas, uneven and without seal where the patterns cerrados resbalan.
The geometry of grooves abiertos expels naturalmente mud, rocks and material empacado while the tyre rota, avoiding the loss of drive by accumulation in the band.
Ribs specialised in the base of grooves avoidsn that the stones perforen the casing while allow your ejection natural during the rotation.
Elegir the pattern of shoulder right is a of decisions more important that a fleet manager or proprietary-operador can tomar to the especificar drive tyres. The drive tyres of open shoulder are designed for applications where the environment operativo requires aggressive drive, resistance a debris and the capacity of maintain the performance in a variedad of conditions of superficie. These are the main casos of use where the tyres of open shoulder superan a your contrapartes of closed shoulder:
The trucks regional that operate in a radio of 320 a 800 km enfrentan a higher variedad of conditions road that the vehicles of long-haul. The routes include streets urbans with baches, roads of acceso a parques industriales, approximations a muelles of freight and highways dryndary rural. The tyres of open shoulder handle the acceleration, braking and giros frequent that require the cycles regional while maintain drive in surfaces varied that these trucks enfrentan a diario.
The trucks that dividen your time between sealed highways and worksites unsealed need drive tyres that rindan in ambos entornos. The patterns of open shoulder provide the drive necessary for subir slopes embarradas, navegar yards of gravel and maintain the control in surfaces of aggregate suelto. The band autolimpiante avoids that the mud and the arcilla se packagingn in surcos, which would eliminate by complete the drive in a tyre of closed shoulder. The carriers of construction materials, the trucks concrete mixers and the tippers se benefician all of drive tyres of open shoulder.
En regions with rains frequent, desice or water estanevery, the side grooves widers of the tyres of open shoulder channel the water outside the contact patch much more eficazmente that the designs of closed shoulder. This reduces the risk of hidroplaneo and maintains a drive positiva during operations in climate humid. Para fleets operating in regions with rainfall diaria, the drive tyres of open shoulder are a specification crítica for the safety.
The mixed service dwrite tony operation in the that the trucks transiten regularmente between driving by highway and conditions off-road or unsealed. This includes operations forestry, transport agricultural, service petrolero, work of utility services and applications municipales. The tyres of open shoulder with compounds resistant to cuts and chunking as the are designed específicamente for surfaces abrasivas and the debris sharp that find the trucks of mixed service. The geometry of surco abierto avoids the puncture by stones while the compounds reinforced resist the cuts and chunking that would destroyn the tyres standard of highway.
Al evaluate drive tyres of open shoulder for your fleet, three specifications technical determinan what so well se will perform a tyre in your application específica. Entender these metrics you ayuda a tomar a decision of purchase informada and avoid desajustes costly between the capacity of the tyre and the demands operativas.
The depth of the band of tread se mide in treintaidosavos of pulgada (market norteamericano) or millimetres (market New Zealand) and se correlaciona directamente with the service life of the tyre and the capacity of drive. The bands more thaneps provide more material for wear out before that the tyre alcance the depth legal minimum, and maintain the volume of surco necessary for the self-cleaning and evacuation of agua. The drive tyres of open shoulder típicamente feature depths between 19/32 and 29/32, with options more thaneps for applications of service severe where the maximum life of band justifica the resistance to the tread lightmente higher. The Hanksugi HS68 delivers 20.6 mm of depth, while the HS28+ Titan Trax offers 22 mm for service extended in demanding conditions of highway New Zealand.
The ratio of empty is the proportion of the área of grooves respecto to the área total of the surface of the band. The drive tyres of open shoulder have a ratio of empty higher that the of closed shoulder by definition, but aun thus existe a variation significativa within the category of open shoulder. A higher ratio of empty improvement the self-cleaning, the evacuation of water and the drive in surfaces sueltas, but reduces the quantity of rubber in contact with the road in a given moment. This means that relations of empty higher intercambian something of stability in highway and life of band by capacity off-road. Para use mainly regional with acceso off-road ocasional, a tyre of open shoulder with ratio of empty moderada as the HS68 equilibra ambas needes. Para use intenso off-road, a pattern more aggressive delivers the advantage of drive that justifica the compromiso.
The ejection of stones is a differencedor crítico between the drive tyres of open shoulder. As the grooves wide of a pattern of open shoulder are more susceptibles a atrapar rocks and debris sharp, the better tyres of open shoulder incorporan ribs or plataformas of ejection in the base of grooves primarios. These features avoidsn that the stones penetren it suficiente for reaching the casing while allow that se liberen during the rotation normal. El system of protection against stones of the Hanksugi HS68 se designed específicamente for this propósito, usedo a geometry of surco that avoids the retention of stones while maintains the flujo of canal abierto necessary for the self-cleaning. operators of fleet that omiten this specification suelen descubrir that the cost ofl damage to the casing exceeds with creces the savings of choose a tyre less capaz.

Hanksugi manufactures three models of drive tyres of open shoulder, each designed for conditions operativas specific and markets regional. The three feature patterns of band of tread aggressive with geometry of surco autolimpiante, protection against stones and casings duraderas designed for retreading.
Robust tyre of drive with pattern M+S and laminations anti-puncture multicapa. El design of open shoulder provides aggressive drive and autolimpiante for roads in badly estado and conditions demanding.
The technology of compound HATT 3+1 delivers lower cost per kilometre with resistance to the tread superior and savings of fuel. Designed for the conditions of highway New Zealand.
The choice between drive tyres of open shoulder and cerrado depends on your conditions operativas main. No design is universalmente superior; each is optimised for different cycles of work. The tabla a continuation resume the differences clave for ayudarte a tomar the decision right for your fleet.
