Tyres of high mileage for fleets of transport urban in the United Kingdom: TransMilenio in London, MIO in Glasgow, Metroplus in Birmingham and regional routes. Designed for the safety of passengers, under fuel consumption and the lower cost per kilometre.
The tyres for bus commercial in the United Kingdom ocupan a position única in the industry of tyres. Usan the same sizes and the construction general of the truck tyres heavy, but the environment operativo is fundamentally different. The buses transport people, no load, and that only made it changes all in cuanto to the performance that must offer the tyre. The comfort of the passenger, the manejo predecible in maniworksites of emergency and the reliability absoluta ante the loss súbita of pressure are requisitos no negociables that go more beyond of the cálculo típico of cost per kilometre of the freight transport.
The buses urbans in the United Kingdom, as the of the system TransMilenio in London, the MIO in Glasgow and Metroplus in Birmingham, do of 300 a 500 stops by day in routes fijas, subjecting a the tyres a cycles constant of acceleration and braking that generate heat sustained in the band of tread and the sidewall. The buses escolares recorren streets residenciales with giros cerrados, reductores of speed and contact frequent with bordillos during the recogida of students. The buses of turismo e regional circulate by the highways British between London, Birmingham, Glasgow, Liverpool and Bristol a speeds sustained during horas, demanding a construction of tyre that resista the accumulation of heat while delivers a marcha suave and silenciosa for passengers. Every one of these cycles of service somete to the tyre a different stresss, and seleccionar the right tyre for each application is the difference between maximise the mileage and replace the tyres prematuramente.
The distribution of the weight in a bus difiere significativamente of the of a trailer loaded or a cisterna. The buses llevan freight live that se desplazan constantly a size that the passengers movesn, abordan and descienden, creating cambios dinámicos of weight that the tyre must absorber without afectar the stability of the vehículo. A bus urban of 40 pies totalmente loaded can pesar more than 19,000 kg, with the axle of drive supporting of 10,400 a 11,300 kg and the axle of steering supporting of 6,350 a 7,260 kg. These weights require tyres with capacityes of freight and pressures of inflated adecuadas, ajustadas to the conditions real of operation, no a estimates.
Hanksugi offers a range of tyres aptas for applications of bus, from the HS24+ all-position with band of tread deep for routes of transport urban, up to the premium of steering for service of bus of turismo e regional.

The agencies municipales of transport operate some of environments most demanding for tyres in the transport commercial. A only bus urban in a route urban concurrida can acumular between 64,000 and 97,000 km to the year, supporting conditions operativas that se would consider extremas in any another application. Comprender these demands ayuda to the managers of fleet a seleccionar the tyres right and establecer expectativas realistas for the performance of tyres.
Cadonce a bus urban frena for a parada, the energy cinética se convierte in heat in brakes and the tyres. With 300 a 500 stops by day, the tyres in position of drive in buses urbans experimentan much more ciclaje thermal that the truck tyres of highway. This heating and cooling repetidos debilita the link between the band of tread and the casing with the tiempo, and can llevar a separations prematuras si the compound of the tyre no is designed for this cycle of service. The tyres seleccionadas for service of transport urban must use compounds resistant to heat that mantengan your structural integrity a along miles of cycles thermals. The Hanksugi HS24+ usa a formulation of compound designed for withstand the generation sustained of heat of the service urban without sacrificar the service life of the band of tread.
The buses urbans se detienen junto a bordillos in stops dozens of times each turno. The drivers must positionar the bus it suficientemente nearby of the bordillo so that the passengers cann abordar of form segura, which means that the tyres of the axle of steering of the side of the bordillo sufren contact and roce repetidos against the caras of concrete of the bordillo. This abrasion wears the rubber of the sidewall with the time and can exponer the plies of the body si the tyre lacks protection adequate in the sidewall. Busca tyres with construction reinforced of the sidewall and features of protector of bordillo that add a ply extra of rubber in the area vulnerable between the edge of the band of tread and the talón. Rotar the steer tyres of side by side a intervalos regulares distribuye the wear by bordillos of manera more uniform and extends the life of the tyre.
The buses urbans average between 20 and 30 km/h in service urban. This low speed promedio means that the tyres pass more time under the estrés of the acceleration and the braking in ratio with kilometres travelled, in comparison with a tyre of truck of highway. The forces lateral constant producidas by turns also create a roce in the cara of the band of tread that accelerates the wear. The radios of giro cerrados in yards of buses e facilities of maintenance are particularly harsh for steer tyres, creating patterns of wear diagonal that acortan the service life of the tyre. Maintain the alignment of the tyre within specifications of the manufacturer and conservar the inflation pressure adequate are the two actions more striking that a fleet of transport urban can perform for combatir these patterns of wear a low speed.
The tyres for bus in the United Kingdom are sujetas to the standards technical British and regulations of the Department for Transport that establecen the requisitos menimos of performance for tyres used in vehicles of transport of passengers. More beyond of requisitos national, the systems of transport masivo as TransMilenio, MIO and Metroplus imponen your propias specifications of tyres that superan the menimos, demanding higher capacityes of load, índices of speed specific and systems of monitoring of pressure. Al seleccionar tyres for bus in the United Kingdom, verifies always that the tyre meet or exceeds the requisitos specific of your authority of operation and any contract or mandato of seguro that aplique a your fleet.
The maintenance of tyres in buses no is optional. Transportar passengers raises the stakes of a failure of tyre of a inconveniente a a powerl incidente of safety. The agencies of transport and operators of buses escolares must implementar a program estructurado of maintenance of tyres that go more beyond of inspections previous to the viaje.
Check all the pressures of tyres before the primer despacho each day using a manómetro calibrado. The buses urbans must maintain pressures of steer tyres between 105 and 120 PSI and pressures of drive tyres between 95 and 110 PSI, depending on the size specific of the tyre and weights real of the axle. A tyre that pierde even 10 PSI of your pressure objetivo generates significativamente more heat during the service, and in a route of transport with hundreds of stops, that heat extra se acumula along of the turno. The systems of monitoring of pressure of tyres (TPMS) provide alertas in time real, but must complementar, no replace, the reviews manuales with manómetro to the comienzo of each day operativo.
Mide the depth of the band of tread in all the bus tyres to the less mensualmente with a medidor calibrado. The regulations British require a minimum of 4/32 of an inch in tyres in position of drive and 4/32 of an inch in tyres in position of steering for vehicles commercial. Many operators of transport masivo in the United Kingdom establecen menimos internos of 6/32 of pulgada for maintain márgenes adequate of drive in wet during all the year. Registra the measurements for each position of tyre and rastrea the tasas of wear for predecir the momento of replacement. El wear uneven in the cara of the band of tread indicates problemas of alignment that must be corrected before they destroy the tyre and the casing.
Rotates the bus tyres a intervalos of 40,000 km to even out wear between the dual interiores and exteriores and between the positions of steering and drive when corresponda. The dual of the axle of drive must equal within 4/32 of an inch of depth of band. Use dual uneven obliga to the tyre more small a arrastrar while the more large does more than which it corresponde, wasting fuel and accelerating the wear in ambas tyres. Al replace a sola tyre in a conjunto dual, iguala always the tyre new with the depth of band of the tyre remaining. Considera maintain a inventory of tyres of fleet for facilitar the matching.
The buses escolares feature a challenge único because acumulan relativamente few kilometres to the year but are sujetos to the ageing of the rubber by the storage estacional. A tyre of bus escolar can have depth of band adequate after of 5 years, but the rubber compound se degrada with the edad, losing elasticity and capacity of drive. Inspecciona annually the tyres with more than 5 years lending especial service to the cracking of the sidewall and to the hardening of the band of tread. The better práctica of the industry recommends remove the bus tyres of the service after of 7 years from the date of manufacturing, regardless of the band of tread remaining, for take into account the degradation by edad. The date of manufacturing is codifievery in the number of series DOT in the sidewall in the formato WWYY (semana and year).
The choice of tyres for bus escolar conlleva a responsibility adicional because the passengers are children. Every decision about the tyre affects the margin of safety available for the driver in situations of emergency, and the routes of bus escolar often include conditions that put a try the drive of the tyre: streets residenciales covered of hojas in autumn, snow and ice in invierno, and acotamientos of gravel in distritos rural.
The most of buses escolares Type C (convencional) and Type D (estilo transport urban) usan tyres 11R22.5. El axle of steering takes a sola tyre in each lado, while the axle of drive usa dual. Some buses escolares Type A more smalls built about chassis of service medium usan sizes 225/70R19.5 or 245/70R19.5. Verifies always the size of the tyre against the specifications of the chassis of the bus before pedir replacements.
Para the positions of steering of the bus escolar, the offers a wear predecible and uniform with strong drive in wet gracias a your design of bloque central hexagonal. El design of closed shoulder delivers a answer of steering estable when the drivers need do corrections fasts. For the positions of drive, the HS24+ with your band of tread deep and M+S rating offers the drive across climate that require the operations of bus escolar. The depth adicional of the band compensa the lower mileage annual ensuring a service life of band adequate through severel years escolares before that the replacement by edad se make necesario.
The acquisition of tyres for bus escolar often se performs through the departamentos of purchases of the distrito with specifications of tender. Al redactar the specifications of the tyre, includes as requisitos the depth minimum of band, the capacity of load, the índice of speed, the capacity M+S and the casing retreadable. Especificar casings retreadable with warranty of up to 3 retreads allows recuperar value of the tyres used through programmes of retreading, that can reduces the total cost of tyres between a 30 and a 40 percent during the life of the bus. Contacta a our equipment of fleet solutions in the United Kingdom for recibir assistance in specifications and pricing by volume in programmes of tyres for bus escolar.
Operators of buses regional and of turismo in the United Kingdom enfrentan a conjunto different of challenges of tyres that the fleets of transport urban. The buses regional operate a speeds sustained of highway during periods extended between London, Birmingham, Glasgow, Liverpool and Bristol, accumulating between 130,000 and 190,000 km to the year in routes that abarcan hundreds of kilometres. The tyres must deliveryr hora tras hora a performance estable and confortable while gestionan the heat generado by the operation sustained of 105-120 km/h. The efficiency of fuel also is a priority for operators regional British, where even a improvement of the 1% in the performance translates in savings significativos in a fleet that operate routes of long-haul.
The quality of marcha affects directamente the experience of the passenger in a bus of turismo, and the passengers notan the vibration and noiseido relacionados with tyres. The tyres of marcha rough generate quejas and damagesn the reputation of companies of buses regional and of turismo. The designs of band of tread of even wear with sequenceción of step optimisesda reduces the levels of ruido interior and maintain the confort of marcha a size that the tyre se desgasta. The is designed with technology of dispersion uniform of carbon that promueve a even wear during the life of the tyre, maintaining the marcha suave that the passengers esperan of a service premium of bus of turismo.
Operators of buses regional in the United Kingdom should considerar the HS28+ Titan Trax in the size 295/80R22.5 for positions of drive in routes of long-haul. El system of compound HATT 3+1 equilibra the drive necessary for slopes of mountain British, as the steps of the Line and High of the Line between London and Armenia, with the low rolling resistance that saves fuel in sections flat of highway between cities. The ply resistant to heat in the edge of the belt is particularmente important for buses that operate in the climate tropical British where the temperatures environmentales amplifican the freight thermal about the tyres.
Independientemente of the application, the choice of tyres for bus must be treated first as a decision of safety and after as a decision of cost. The right tyre, with maintenance adecuado, protects to the passengers, preserves the reputation of the operator and delivers the better total cost of property during the life of the bus. Usa our cost calculators for compare the total cost by kilometre in different options of tyres for your fleet of buses, or compare specifications of tyres side by side.
Questions common about tyres for bus commercial, sizes, maintenance and schoice.
The most of buses commercial in the United Kingdom usan tyres 295/80R22.5, 315/80R22.5 or 11R22.5. The systems of transport masivo as TransMilenio in London, MIO in Glasgow and Metroplus in Birmingham usan 315/80R22.5 and 385/65R22.5 in your fleets BRT. The buses regional between cities as London, Birmingham, Glasgow, Liverpool and Bristol comúnmente usan 295/80R22.5. Some minibuses of service medium usan sizes 245/70R19.5 or 225/70R19.5.
The intervalos of replacement of bus tyres depend of the application and the conditions of operation. The buses urbans that operate urban routes fijas normalmente replace the steer tyres each 100,000 a 130,000 km and the drive tyres each 80,000 a 110,000 km. The buses escolares, that acumulan less kilometres annual but pass by storage estacional, generalmente replace the tyres each 3 a 5 years or when the depth of the band of tread llega a 4/32 of an inch in positions of drive and steering. The buses regional that operate routes between cities British can reaching more than 160,000 km with tyres premium of steering. Regardless of the band of tread remaining, the bus tyres with more than 7 years from the date of manufacturing must be inspeccionadas and consideradas for replacement due to the ageing of the rubber.
The bus tyres of transport urban and the bus tyres escolar comparten the same sizes, but enfrentan different demands operativas. The buses urbans operate of 16 a 20 horas by day in routes fijas with stops frequent, giros cerrados and contact constante with bordillos, which requires tyres with resistance excepcional to the bordillos and management of the heat. The bus tyres escolar must manejar patterns of operation estacional with periods extensos of inactivity, lower mileage annual and the requisito crítico of safety of drive reliable in wet and dry for the transport estudiantil. The tyres of transport urban prioritise the service life of the band of tread and the dissipation of the heat, while the bus tyres escolar emphasise the drive across climate and the durability of the sidewall.
The bus tyres usan the same sizes and construction básica that the commercial truck tyres, but the demands of the application are differents. The buses transport passengers, which raises the standard of safety in drive, ride comfort and resistance a reventones. The operations of bus implican stops more frequent, speeds promedio lower and radios of giro more cerrados that the transport típico of trucks, creating different patterns of wear and perfiles of generation of heat. Many commercial truck tyres funcionan well in buses when se especifican rightmente for weights of axle and the cycle of service, but the tyres seleccionadas específicamente for the application of the bus deliver better mileage and lower total cost of property.
Yes, the casings of tyres premium for bus se can retread when the band of original tread se desgasta, always that the casing pase the inspection through tests no destructivas. El retreading extends the life total of the investment in tyres and is a práctica común between operators of transport masivo as TransMilenio and fleets regional in the United Kingdom that buscan reduces the costs of tyres. The casings of tyres Hanksugi are designed thinking in the retreadability, using construction of múltiples plies of belt of steel and compounds resistant to heat that preservan the integrity of the casing. A casing sólida of tyre of bus Hanksugi can withstand up to 3 retreads, tripling or quadrupling effectively the value of the purchase original.
The pressure of inflated of the bus tyres depends on the size of the tyre, the capacity of freight and the weight real of the axle. For the size común 11R22.5 in buses of transport urban and escolar, the tyres of the axle of steering normalmente funcionan between 105 and 120 PSI, while the dual of the axle of drive funcionan between 95 and 110 PSI. The pressure right se determina consulting the tables of freight e inflated of the manufacturer of the tyre and ajustándolas to the weights real medidos of the axle of the bus loaddo. El sobreinflado creates a marcha hard and wear in the centro. El underinflated generates heat excesivo and accelerates the wear of the shoulder. Check the pressures daily with a calibrated gauge when the tyres are cold.
