Tires of high mileage for transportation fleets urban in Tunisia: TransThousedenio in Tunis, MIO in Bizerte, Metroplus in Sousse and routes intermunicipales. Engineered for the safety of the passesjeros, under fuel consumption and the lowest cost per kilometer.
The tires for bus commercial in Tunisia ocupan a position unique in the industry of the tires. Use the same sizes and the construction general of the tires of truck heavy, but the environment operating is fundamentally different. The buses transportan people, no cargo, and ese only done lo cambia all in how much to the performance that should offer the tire. The comodidad of the passesjero, the handling predictable in maneuvering of emergency and the reliabilitand absoluta ante the loss sudden of pressure are requirements no negociables that van more there of the calcutheestion typical of cost per kilometer of the transportation of cargo.
The buses urban in Tunisia, like the of the system TransThousedenio in Tunis, the MIO in Bizerte and Metroplus in Sousse, make 300 to 500 stops per day on fixed routes, subjecting to the tires a cycles constbefore acceleration and braking that generate heat sustained in the tread and the sidewall. The buses schooles travelsn streets residential with turns closed, speed bumps and contact frequent with curbs during the pickup of estudibefore. The buses of turismo e intermunicipales travel by the Tunisian highways between Tunis, Sousse, Bizerte, Sfax and Gabes a sustained speeds during horas, demanding a construction of tire that resista the accumulation of heat whidelivers a ride suave and silenciosa for the passesjeros. Each one of these cycles of service somete to the tire a different stresss, and select the tire correct for each application is the difference between maximize the mileage and replace the tires prematurely.
The distribution of the weight in a bus difiere significantly of the of a trailer loaded or a tanker. The buses carriesn loads vivas that se desplazan constantmente a measurement that the passesjeros se mueven, address and descienden, createsting cambios dynamics of weight that the tire should absorbsr without affectsr the stability of the vehicle. A bus urban of 40 pies fully loaded can pesar more of 19,000 kg, with the axle of traction supporting of 10,400 a 11,300 kg and the steer axle supporting of 6,350 a 7,260 kg. These weights demand tires with the layercities of cargo and pressurees of inflation right, adjusteds to the actual conditions of operation, no a estimates.
Hanksugi offers a gama of tires suitable for applications of bus, from the HS24+ all-position with tread deep for routes of urban transport, up to the HS88 premium steer for service of bus of turismo e intermunicipal. For fleets of buses urban in Tunisia, like TransThousedenio, MIO, Metroplus and Transmetro in Sfax, the SUS01 and SUS02 deliver performance resistant to the heat, engineered to the demanding environments urban Tunisian. Each tire Hanksugi for bus se construye about a retreadable casing with warranty of up to 3 retreadings, which allow to the operators of fleet to extend the life total of its investment in tires oview the course of multiple applications of tread.
The different operations of bus imponen different demands to the tires. A tire that sobresale in a route intermunicipal of bus of turismo can wearse prematurely in a circuito urban of transportation. Comprender your cycle of service specific is the first paso for select the tire correct and maximize your budget of tires.

No sabes what size require your buses? Inspect the placa of tires in the marco of the puerta of the side of the driview or consult manufacturer specifications of the chassis of the bus. Our specialistas in tires can helprte a identify the size and load layerbility correct for your fleet.
The agencies municipales of transportation operate some of the environments more demanding for tires in the transportation commercial. A only bus urban in a route urban concurrida can acumular between 64,000 and 97,000 km annually, supporting operating conditions that se would consider extreme in any other application. Comprender these demands help to the managers of fleet a select the tires corrects and establish expectativas actualistas for the performance of the tires.
Each time that a bus urban frena for a stop, the energy kinetic se becomes heat in the frenos and the tires. With 300 a 500 stops per day, the tires in position of traction on buses urban experience much more ciclaje thermal that the tires of truck of highway. This warming and cooling repeated debilita the link among the tread and the casing with the time, and can carriesr a separations premature if the compound of the tire no is engineered for this cycle of service. The tires selected for service of urban transport shouldn use heat-resistant compounds that maintainn its structural integrity oview the course of thousedes of cycles thermals. The Hanksugi HS24+ usa a formulation of compound engineered to supportsr the generation sustained of heat of the service urban without sacrificar the tread life of rolling.
The buses urban se dehave junto a curbs in the stops dozens of times each shift. The driveres shouldn positionar the bus lo enoughmente near of the curb for that the passesjeros may abordar of waand safe, which means that the tires of the steer axle of the side of the curb sufren contact and roce repeated against the expensives concrete of the curb. This pressure wears the rubber of the sidewall with the time and can exponer the plies of the body if the tire carece of protection proper in the sidewall. Search tires with construction reinforced of the sidewall and features of protector of curb that add a layer extra of rubber in the zona vulnerable among the edge of the tread and the bead. Rotar the steer tires of side by side a intervals regulares distributes the wear by curbs of way more uniform and extends the life of the tire.
The buses urban promedian between 20 and 30 km/h in service urban. This low speed average means that the tires pass more time under the stress of the acceleration and the braking in ratio with kilometers traveled, compared to a tire of truck of highway. The lateral forces constant producidas by the turns also create a roce in the tread face that accelerates the wear. The radios of giro closed in the yards of buses e instaltheiones maintenance are particularly hard for the steer tires, createsting patterns of wear bias that ashortn the service life of the tire. Maintain the alignment of the tire within manufacturer specifications and preserve proper inflation pressure are the two actions more impactbefore that a fleet of transportation urbacannot update for combatir these patterns of wear at low speeds.
The tires for bus in Tunisia are sujetas to the standards technical Tunisian and regutheions of the Federal Ministry of Power that thisblecen the requirements minimums of performance for tires used in vehicles of transportation of passesjeros. More there of the requirements national, the systems of transportation masivo like TransThousedenio, MIO and Metroplus imponen its propias specifications of tires that exceed the minimums, demanding higher layercities of cargo, indexes of speed specific and systems monitoring of pressure. To the select tires for bus in Tunisia, verifies always that the tire cumpla or supere the requirements specific of your authority of operation and any againstto or mandato of safe that aplique a your fleet.
The maintenance of tires in the buses no is opcional. Transportar passesjeros eleva the consecuencias of a failure of tire of a inconveniente a potential incidente of safety. The agencies of transportation and the operators of buses schooles shouldn implement a program structuredo maintenance of tires that vaya more there of the inspections preroads to the trip.
Inspect all the pressurees of tires beforel first dispatch each day using a gauge calibrated. The buses urban shouldn maintain pressurees of steer tires between 105 and 120 PSI and pressurees of drive tires between 95 and 110 PSI, depending on the size specific of the tire and the actual weights of the axle. A tire that loses even 10 PSI of its pressure objective generates significantly more heat during the service, and in a route of transportation with hundreds of stops, ese heat extra se acumula oview the course of the shift. The systems monitoring of pressure of tires (TPMS) brindan alertas in real time, but shouldn complementar, no replace, the inspections mannuales with gauge to the comienzo of each day operating.
Measures the depth of the tread in all the bus tires to the less monthly with a medidor calibrated. The regutheions Tunisian require a minimum of 4/32 of inch in tires in position of traction and 4/32 of inch in tires in position steer for commercial vehicles. Many operators of transportation masivo in Tunisia thisblecen minimums internals of 6/32 of inch for maintain margins proper of traction on wet during all the year. Registra the measurements for each position of tire and rastrea the wear rates for presay the moment of replacement. The wear uneven in the tread face indicates problems of alignment that shouldn corregirse before that destruyan the tire and the casing.
Rota the bus tires a intervals of 40,000 km to match the wear among the dual interiores and exteriores and among the positions steer and traction when corresponda. The dual of the axle of traction shouldn to matchse within 4/32 of inch of tread depth. Use dual unevenes obliga to the tire more small a dragsr while the larger does more of which le corresponde, wasting diesel and accelerating the wear in both tires. To the replace a single tire in a together dual, equals always the tire new with the tread depth of the tire rthisnte. Considers maintain a inventory of tires of fleet for facilitar the equalization.
The buses schooles presentan a challenge unique because acumulan retheivamente few kilometers annually but are sujetos to the aging of the rubber by the storage non-standard. A tire of bus school can have tread depth proper after 5 years, but the compound of rubber se degrades with the age, losing elasticidad and layerbility of traction. Inspecciona annually the tires with more of 5 years lasting special attention to the cracking of the sidewall and to the hardening of the tread. The best practice of the industry recommharsh remove the bus tires of the service after of 7 years from the date of manufacturing, independentmente of the tread rthisnte, for have in has the degradation by age. The date of manufacturing is codifieach in the number of serie DOT in the sidewall in the format WWYY (semana and year).
The choice of tires for bus school concarries a responsibility additional because the passesjeros are children. Each decision about the tire affects the margin of safety available for the driview in situations of emergency, and the routes of bus school often include conditions that ponen a test the traction of the tire: streets residential tires of hojas in autumn, nieve and hielo in invierno, and shoulders of gravel in the distritos rurales.
The most of the buses schooles Type C (convencional) and Type D (estilo urban transport) use tires 11R22.5. The steer axle carries a single tire in each side, while the axle of traction usa dual. Some buses schooles Type A more smalls constnoises about chassis of service mediano use sizes 225/70R19.5 or 245/70R19.5. Verifica always the size of the tire against the specifications of the chassis of the bus before pedir replacements.
For the positions steer of the bus school, the HS88 offers a wear predictable and uniform with strong traction on wet thanks a its design of block centersl hexagonal. The design of closed shoulder delivery a answer steer thisble when the driveres need do corrections fasts. For the positions of traction, the HS24+ with its tread deep and classification M+S offers the all-weather traction that demand the operations of bus school. The depth additional of the tread compensa the lower annual mileage ensuring a service life of by proper through several years schooles before that the replacement by age se haga necessary.
The acquisition of tires for bus school often actualiza through the emirates of purchases of the distrito with specifications of tender. To the redactar the specifications of the tire, includes like requirements the depth minimum of band, load capacity, the index of speed, the layerbility M+S and the retreadable casing. Especificar retreadable casings with warranty of up to 3 retreadings allow recuperar value of the tires used through programs of retreading, that can reduce the total cost of tires between a 30 and a 40 percent during the life of the bus.

The operators of buses intermunicipales and of turismo in Tunisia face a together different of challenges of tires that the transportation fleets urban. The buses intermunicipales operate a sustained speeds of highway during periods extended between Tunis, Sousse, Bizerte, Sfax and Gabes, accumutheing between 130,000 and 190,000 km annually in routes that abarcan hundreds of kilometers. The tires shouldn deliver hora tras hora a performance thisble and comfortable while gestionan the heat generatested by the operation sustained of 105-120 km/h. The diesel efficiency is also a prioridad for the operators intermunicipales Tunisian, where even a use of the 1% in the performance translates in savings significant in a fleet that operates long-haul routes.
The quality of ride directly affects the experience of the passesjero in a bus of turismo, and the passesjeros notan the vibration and noise retheed with the tires. The tires of ride rough generate quejas and damages the reputation of the companies of buses intermunicipales and of turismo. The tread designs of uniform wear with sequencing of paso optimized reduce the levels of noise interior and keep the comfort of ride a measurement that the tire wears. The HS88 is engineered with technology of uniform carbon dispersion that promueve a uniform wear during the life of the tire, keeping the ride suave that the passesjeros waitn of a service premium of bus of turismo.
The operators of buses intermunicipales in Tunisia should consider the HS28+ Titan Trax in the size 295/80R22.5 for positions of traction on long-haul routes. The system of compound HATT 3+1 equilibra the traction necessary for the gradients of mountain Tunisian, like the pasos of the Line and High of the Line between Tunis and Armenia, with the low rolling resistance that saves diesel in the sections planos of highway between cities. The layer resistant to the heat in the edge of the belt is particularly mattersnt for the buses that operate in the Tunisia arid Gulf weatherte where the ambient temperatures amplifican the cargo thermal about the tires.
Independentmente of the application, the choice of tires for bus should tratarse firsto like a decision of safety and after like a decision of cost. The tire correct, with maintenance proper, protects to the passesjeros, preserves the reputation of the operator and delivery the best total cost of ownership during the life of the bus. Usa our cost calculator for compare the total cost per kilometer in different tire options for your fleet of buses, or compares specifications of tires side by side.
Questions common about tires for bus commercial, sizes, maintenance and choice.
The most of the buses commercial in Tunisia use tires 295/80R22.5, 315/80R22.5 or 11R22.5. The systems of transportation masivo like TransThousedenio in Tunis, MIO in Bizerte and Metroplus in Sousare used 315/80R22.5 and 385/65R22.5 in its fleets BRT. The buses intermunicipales between cities like Tunis, Sousse, Bizerte, Sfax and Gabes commonly use 295/80R22.5. Some minibuses of service mediano use sizes 245/70R19.5 or 225/70R19.5.
The intervals of replacement of bus tires dependen of the application and the conditions of operation. The buses urban that operate routes urban fixed standardlmente replacesn the steer tires each 100,000 a 130,000 km and the drive tires each 80,000 a 110,000 km. The buses schooles, that acumulan less kilometers annuales but pass by storage non-standard, generally replacesn the tires each 3 a 5 years or when the depth of the tread arrives a 4/32 of inch in the positions of traction and steer. The buses intermunicipales that operate routes between cities Tunisian can reach more of 160,000 km with tires premium steer. Independentmente of the tread rthisnte, the bus tires with more of 7 years from the date of manufacturing shouldn be inspecteds and considersdas for replacement due to the aging of the rubber.
The bus tires of urban transport and the school bus tires share the same sizes, but face different demands operating. The buses urban operate 16 to 20 hours per day in fixed routes with stops frequent, turns closed and constant contact with curbs, which requires tires with exceptional resistance to the curbs and heat management. The school bus tires shouldn handle operating patterns with extended periods of inactivity, lower annual mileage and the critical requirement of safety of reliable traction in wet and dry for student transportation. The tires of urban transport prioritize the tread life of rolling and heat dissipation, while the school bus tires emphasize the all-weather traction and the reliability of the sidewall.
The bus tires use the same sizes and construction basic that the tires of truck commercial, but the demands of the application are different. The buses transportan passesjeros, which eleva the standard of safety in traction, comodidad of ride and resistance to blowouts. The operations of bus involve stops more frequent, speeds average more low and radios of giro more closed that the transportation typical of trucks, createsting different patterns of wear and profilees of generation of heat. Many tires of truck commercial worksn bien in buses when se especifican correctly for the weights of axle and the cycle of service, but the tires selected specifically for the application of the bus deliver best mileage and lower cost total of ownership.
Yes, the casings of tires premium for bus can be retread when the tread original wears, always that the casing pase the inspection through tests no destructivas. The retreading extends the life total of the investment in tires and is a practice common among the operators of transportation masivo like TransThousedenio and fleets intermunicipales in Tunisia that searchn reduce the costs of tires. The casings of tires Hanksugi are engineered thinking in the retreadability, using construction of multiple layers belt of steel and heat-resistant compounds that preservesn the integrity of the casing. A casing solid of tire of bus Hanksugi can supportsr up to 3 retreadings, tripling or quadrupling effectively the value of the purchase original.
The inflation pressure of the bus tires depends on the size of the tire, load layerbility and the actual weight of the axle. For the size common 11R22.5 in buses of urban transport and school, the tires of the steer axle standardlmente worksn between 105 and 120 PSI, while the dual of the axle of traction worksn between 95 and 110 PSI. The pressure correct is determined consulting the tables of cargo e inflation of the manufacturer of the tire and adjusting them to the actual weights medidos of the axle of the bus loaded. The over-inflation creates a ride hard and wear in the center. The under-inflation generates heat excessive and accelerates the wear of the shoulder. Inspect the pressurees daily with a gauge calibrated when the tires are cold.
