What LAU603 Is Built For
LAU603 is a radial bus tyre designed for all positions on coaches and urban buses operating primarily on highways. It is built for consistent performance across steering, drive and non-drive axles, with a tread pattern that reduces uneven wear and maintains grip over extended use. The tyre supports multiple ply ratings and load indices across nine sizes, from 9R22.5 to 295/80R22.5, with tread depths ranging from 15.0 mm to 17.0 mm. It is suitable for fleets running scheduled routes with high daily mileage and minimal off-road exposure.
Manufacturer Feature Claims
- Suitable for all axle of bus riding on highway
- Long life
- Good grip performance
- Low eccentric wear
Key Benefits
- Long life tread pattern reduces replacement frequency across all axle positions
- Low eccentric wear minimises irregular tread wear and extends casing life
- Good grip performance maintained under high-speed highway conditions
- Multiple sizes and ply ratings allow one pattern to cover multiple bus models
- Tread depth from 15.0 mm to 17.0 mm supports long service life on high-mileage routes
Problems It Solves
- Fleets using different tyres for steering, drive and trailing axles face higher inventory and fitting complexity
- Uneven wear on bus tyres leads to early casing failure and higher replacement costs
- Short tread life on high-mileage routes increases total cost of ownership
- Lack of a single pattern suitable for all axles forces multiple purchase orders and documentation
- Inconsistent grip performance across axle positions affects handling and safety on long routes
Who It Is For
- Coach operators buying tyres for long-haul scheduled services
- Urban transit authorities standardising on one radial pattern for all bus axles
- Fleet managers reducing spare tyre stock by using a single pattern across all positions
- Importers sourcing tyres for multiple bus models under one container load
- Distributors supplying regional bus fleets with a consistent, long-life pattern
Application Scenarios
- Scheduled coach services running daily between cities on paved highways with minimal off-road stops
- Urban bus fleets operating on fixed routes with high daily mileage and consistent axle loads
- Fleets replacing multiple tyre patterns across steering, drive and trailing axles with one uniform pattern
- Operators seeking reduced inventory complexity by standardising on a single all-position radial
- Maintenance teams looking to reduce tyre rotation frequency due to low eccentric wear
Technical Features
- Radial casing construction with uniform tread depth across all listed sizes
- Tread pattern designed to reduce eccentric wear and maintain even tread wear
- Good grip performance maintained at highway speeds and under heavy load
- Suitable for all axle positions on highway-running coaches and urban buses
- Tread depth ranges from 15.0 mm to 17.0 mm, supporting extended service life

Where This Pattern Wins and Where It Does Not
Compared With Tyres with different patterns for steering, drive and trailing axles
LAU603 eliminates the need for multiple patterns, reducing stock, fitting labour and inventory complexity
Compared With Tyres with shorter tread life or higher eccentric wear
The LAU603 pattern extends casing life and reduces irregular wear, lowering replacement frequency
Compared With Tyres designed for off-road or mixed-surface use
LAU603 is optimised for highway use; off-road patterns would wear faster and run noisier on paved routes
Use Guide
- Match ply rating and load index to actual axle load, not to the maximum available
- Check standard rim size against your wheel: 6.75 for 9R22.5, 7.50 for 10R22.5, 8.25 for 11R22.5 and 275/70R22.5, 9.00 for 12R22.5 and 295/80R22.5
- Inflate to the pressure shown in the size table for your load and fitment type
- Rotate tyres between positions before irregular wear becomes significant, especially on high-mileage routes
- Inspect tread for early signs of eccentric wear during routine checks to extend casing life
LAU603 Buying Questions
What is the minimum order quantity?
We load by full container. A 40HQ of LAU603 typically fills at container weight rather than volume, so the practical minimum is one container. Mixed loads across sizes and patterns are accepted.
What is the lead time?
It depends on whether the size is in stock at the plant or needs to be produced. We confirm current availability with the plant at the time of quotation.
Which sizes are available?
9R22.5, 10R22.5, 11R22.5, 12R22.5, 275/70R22.5, 295/80R22.5. Ply ratings include 14, 16, 18. Full load index, rim and pressure data for each size is in the size table.
Can you supply DOT or ECE marked tyres?
Marking requirements vary by destination. Tell us your import market and we confirm what marking the plant can supply on that size before you place the order.
What warranty do you give?
One year against manufacturing defect on all tyres we supply, with claims handled by us directly. Cargo transportation insurance is provided on the shipment.
Can you ship a mixed container with other patterns?
Yes. Most of our customers load one container across several patterns and sizes, which is the main reason to buy through us rather than from a single plant.
Is this tyre suitable for off-road use?
No. LAU603 is designed for highway use on coaches and urban buses. It is not suitable for off-road or mixed-surface routes.
