- Bias OTR
LL66B is a bias OTR tyre designed for loaders operating under seriously tough service conditions in tunnels. The flat and smooth tread pattern reduces the risk of punctures from stone, while the construction delivers excellent wear and cut resistance. 00-20, with a 14 ply rating, suitable for high-load applications in confined, abrasive environments.
What LL66B Is Built For
LL66B is a bias OTR tyre designed for loaders operating under seriously tough service conditions in tunnels. The flat and smooth tread pattern reduces the risk of punctures from stone, while the construction delivers excellent wear and cut resistance. It is supplied in one size, 9.00-20, with a 14 ply rating, suitable for high-load applications in confined, abrasive environments. The tyre is built for durability in continuous, heavy-duty operation where surface debris and impact are constant threats.
Manufacturer Feature Claims
- Available for loaders operating under seriously tough service conditions in tunnels
- Excellent wear and cut resistance
- Flat and smooth tread improves the puncture resistance to stone
Key Benefits
- Flat and smooth tread pattern improves resistance to punctures from stone and debris
- Excellent wear and cut resistance for extended service life in harsh tunnel conditions
- 14 ply rating supports high load capacity under continuous heavy-duty use
- Single size 9.00-20 with 7.0 rim width ensures compatibility with standard loader wheels
- Designed specifically for loaders in tunnels, where surface abrasion and impact are frequent
Problems It Solves
- Tyres failing prematurely due to punctures from stone and debris in tunnel environments
- Frequent tyre replacements caused by poor cut and wear resistance under continuous heavy load
- Mismatched ply ratings leading to underperformance or casing failure in high-load loader applications
- Lack of a dedicated tunnel-specific OTR pattern for loaders with consistent performance
- Inconsistent availability of tyres with proven durability in confined, abrasive working zones
Who It Is For
- Mining and tunnel construction contractors sourcing tyres for loader fleets
- Fleet operators managing loaders in underground or high-abrasion environments
- Distributors supplying OTR tyres to contractors in mining, tunneling and infrastructure projects
- Importers needing a single, reliable OTR tyre pattern for loaders in tough service conditions
- Contractors bidding on government or infrastructure tenders requiring durable, proven OTR tyres
Application Scenarios
- Loaders working in underground tunnels with rough, uneven surfaces and rock debris
- Mining and quarry loaders operating in confined spaces with frequent impacts and sharp edges
- Construction loaders in tunnel projects where tyre damage from stone and metal fragments is common
- Heavy-duty loader fleets requiring consistent performance without frequent tyre replacement
- Operations where downtime from tyre failure must be minimized due to limited access or safety constraints
Technical Features
- Bias construction with 14 ply rating for high-load and impact resistance
- Flat and smooth tread pattern designed to reduce stone penetration and puncture risk
- Section width of 725 mm and overall diameter of 255 mm for stable performance on loader wheels
- Rim width of 7.0 inches ensures proper fit and load distribution
- Max load of 4375 kg at 1015 kPa (10 km/h) for high-duty loader applications

- Tread compound specified for wear and cut resistance in abrasive environments
- Sidewall compound and gauge designed to resist impact and abrasion in tunnel conditions
From Size List to Loaded Container
Confirm the 9.00-20 size, 14 ply rating, and load index against the loader’s axle and rim width
We quote FOB or CIF based on your load port and confirm current plant availability
Production or stock allocation is confirmed with the plant before deposit is required
Container is loaded, insured, and shipped with certificate of origin and full export documentation
Quality and After Sales
- Every tyre supplied carries a one year warranty against manufacturing defect
- Warranty claims are handled directly by us, not passed back to the plant
- Cargo transportation insurance is arranged on every shipment
- DOT, ECE, and other marking requirements are confirmed against your import market 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 OTR tyres with deep lug patterns
Deep lugs grip better in mud but are more prone to stone retention and puncture; LL66B’s flat tread reduces this risk in tunnel environments
Compared With Radial OTR tyres for loaders
Radial construction offers better fuel efficiency and heat dissipation but may have lower cut resistance in abrasive tunnel conditions
Compared With General-purpose OTR tyres
General-purpose tyres lack the specific wear and cut resistance needed for continuous tunnel service; LL66B is built for that duty
Use Guide
- Verify the 9.00-20 size and 7.0 rim width match your loader wheel before ordering
- Inflate to 1015 kPa at 10 km/h maximum speed to support the 4375 kg load
- Inspect the tread surface after each shift for embedded stone or debris that could lead to puncture
- Rotate tyres before uneven wear becomes significant, especially on loaders with one-way load patterns
- Monitor for sidewall damage from impacts; the bias construction resists bruising but is not immune to sharp objects
LL66B Buying Questions
What is the minimum order quantity?
We load by full container. The 9.00-20 size fills a container by 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 9.00-20 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?
Only 9.00-20 with a 14 ply rating is available. The load, pressure, section width, and diameter are fixed as per the size table.
Is this tyre suitable for tunnels?
Yes. It is specifically designed for loaders operating under seriously tough service conditions in tunnels, with flat and smooth tread for stone puncture resistance.
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 the 9.00-20 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.
