LL1
- 2 sizes
- Bias
LL1 is a bias truck and bus tyre designed for regional and intercity freight operations where consistent load handling and extended casing life are required. The tread pattern delivers low rolling resistance and good wear performance under steady-duty conditions, with heat dissipation features to reduce thermal stress during long runs.
What LL1 Is Built For
LL1 is a bias truck and bus tyre designed for regional and intercity freight operations where consistent load handling and extended casing life are required. The tread pattern delivers low rolling resistance and good wear performance under steady-duty conditions, with heat dissipation features to reduce thermal stress during long runs. It is available in two ply ratings, 16 and 18, for the 12.00-24 size, covering drive and trailer axle positions in medium-duty trucks and buses. The tyre maintains a consistent tread depth of 15.0 mm across both ratings and supports load indices up to 158/154 with a speed symbol of G, suitable for sustained highway use.
Manufacturer Feature Claims
- Low rolling resistance
- Good Wear and crack resistance
- Good heat dissipation
Key Benefits
- Low rolling resistance reduces fuel consumption on long-haul regional routes
- Good wear and crack resistance extends casing life under steady-duty operation
- Good heat dissipation helps prevent overheating during prolonged highway driving
- Two ply ratings (16 and 18) allow matching to axle load without overspecifying
- Consistent tread depth of 15.0 mm across both ratings ensures predictable wear and retreadability
Problems It Solves
- Bias tyres with poor heat dissipation fail early under sustained highway use
- Cracking in the tread or shoulder area shortens casing life on long-haul routes
- High rolling resistance increases fuel cost on daily regional runs
- Lack of consistent tread depth across ply ratings makes retreading planning difficult
- Need to source multiple patterns for drive and trailer axles increases inventory and fitting complexity
Who It Is For
- Tyre distributors supplying regional freight and bus fleets in Asia, Africa and South America
- Fleet operators replacing bias tyres with improved heat and wear performance
- Importers sourcing mixed container loads of bias tyres for regional and urban transport
- Government tender buyers requiring durable, low-maintenance tyres for public transport
Application Scenarios
- Regional freight trucks operating daily between distribution hubs on paved roads
- City and intercity buses running fixed routes with consistent passenger loads
- Medium-duty delivery vans used for scheduled freight with limited off-road exposure
- Fleets replacing older bias tyres that fail prematurely due to heat or cracking
- Operators seeking a single bias pattern that covers both drive and trailer axles
Technical Features
- Bias construction with tread pattern designed for low rolling resistance
- Tread compound engineered for good wear and crack resistance under steady load
- Sidewall and casing construction designed for good heat dissipation during long runs
- Tread depth of 15.0 mm maintained across both 16 and 18 ply ratings
- Standard rim width of 8.5 inches for both size variants

- Cargo transportation insurance is arranged on every shipment
- DOT, ECE and other markings are confirmed against your market requirement before loading
Customisation Options
- Mixed container loading across sizes, patterns and brands to match your order book
- Certificate of origin issued to suit your import duty position
- Sidewall branding and private label subject to plant minimum order quantity
- Label, marking and packaging adjusted to the destination market requirement
Where This Pattern Wins and Where It Does Not
Compared With Standard bias tyres without heat dissipation features
LL1 reduces thermal stress during long runs, which helps prevent casing failure and extends service life
Compared With Higher ply rating bias tyres not needed for actual axle load
LL1 offers two ply ratings to match load without overspecifying, reducing cost and ride harshness
Compared With Radial truck tyres in the same size range
LL1 has lower rolling resistance than typical bias tyres but is not designed for high-speed or heavy-duty off-road use
Use Guide
- Match ply rating to your actual axle load; do not overspecify to save cost and improve ride quality
- Check rim width against your wheel: 8.5 inches is standard for both 16 and 18 ply ratings
- Inflate to the pressure shown for your load in the size table; dual and single fitment pressures differ
- Monitor tread wear regularly; consistent 15.0 mm depth supports predictable retreading
- Inspect for cracking in the tread shoulder area after long runs to catch early signs of failure
LL1 Buying Questions
What is the minimum order quantity?
We load by full container. A 40HQ of 12.00-24 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 has to be produced. We confirm current availability with the plant at the time of quotation rather than quoting a standard figure.
Which sizes are available?
12.00-24 in 16PR and 18PR. Full load index, rim and pressure data for each is in the size table on this page.
Is this tyre suitable for drive and trailer axles?
Yes. The 12.00-24 size is rated for both drive and trailer axle positions in medium-duty trucks and buses.
Can you supply DOT or ECE marked tyres?
Marking requirements vary by destination. Tell us the 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 itself.
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.
