- 2 sizes
- Off Road
LDM991 is a radial truck tyre designed for off-road all-position use, built to handle the demands of heavy-duty operations on unpaved terrain. The tyre is suitable for use on dump trucks, loaders, excavators and other off-road vehicles operating in mining, quarrying, construction and agricultural environments.
What LDM991 Is Built For
LDM991 is a radial truck tyre designed for off-road all-position use, built to handle the demands of heavy-duty operations on unpaved terrain. The tyre is suitable for use on dump trucks, loaders, excavators and other off-road vehicles operating in mining, quarrying, construction and agricultural environments. It features a deep, aggressive tread pattern optimized for traction and self-cleaning in mud, gravel and loose soil. Two sizes are available: 14.00R20 with 18PR and 20PR, covering a wide range of axle loads and operating pressures. The tread depth of 370 mm provides long casing life and retreadability. The tyre is constructed for durability under high-impact conditions and is rated for continuous operation in severe off-road environments.
Manufacturer Feature Claims
- Suitable for Off Road Conditions
Key Benefits
- Deep 370 mm tread depth supports long casing life and multiple retreads
- All-position design allows use on front, rear and drive axles of off-road vehicles
- 14.00R20 sizes with 18PR and 20PR cover a broad range of load and pressure requirements
- High load capacity up to 4500 kg dual and 5000 kg single at 750 kPa
- ETRTO standard marking ensures compliance with international off-road tyre regulations
Problems It Solves
- Off-road tyres that wear out quickly due to inadequate tread depth and weak casing construction
- Need for multiple tyre patterns for different axle positions, increasing stock and fitting complexity
- Inconsistent performance on loose or muddy surfaces due to poor self-cleaning tread design
- Lack of availability of 14.00R20 sizes with high load index and 20PR in off-road applications
- Difficulty in sourcing a single tyre that meets ETRTO standards for off-road use
Who It Is For
- Mining and quarry contractors buying tyres by the container for off-road fleets
- Construction companies sourcing tyres for loaders, excavators and dump trucks
- Agricultural dealers supplying off-road tyres for tractors and field transport
- Fleet operators managing mixed-axle off-road vehicles with consistent fitment needs
- Importers who need a single supplier for mixed off-road tyre containers across sizes and brands
Application Scenarios
- Dump trucks operating in open-pit mines with unsealed haul roads and soft ground
- Excavators and loaders moving material across gravel and muddy construction sites
- Agricultural tractors and transport vehicles working on farm tracks and field edges
- Quarry haul trucks navigating steep, loose-surfaced ramps and uneven terrain
- Fleets requiring one tyre pattern for multiple axle positions across off-road duty
Technical Features
- Radial truck tyre construction with casing designed for off-road all-position use
- Deep 370 mm tread depth across both sizes, supporting extended casing life
- Aggressive tread pattern optimized for traction and self-cleaning in mud and gravel
- ETRTO standard marking confirmed for compliance with international off-road tyre requirements
- All-position fitment allows use on front, rear and drive axles without performance loss

Where This Pattern Wins and Where It Does Not
Compared With Standard on-road truck tyres
LDM991 has a deeper tread and stronger casing for off-road use; on-road use may reduce tread life and increase rolling resistance
Compared With Tread patterns designed for highway use
The aggressive tread of LDM991 cleans itself better in mud and gravel but runs noisier and wears faster on paved roads
Compared With Single-axle position off-road tyres
All-position design allows use on front, rear and drive axles without needing separate patterns for each position
Use Guide
- Match ply rating to your actual axle load; overspecifying increases cost and reduces ride comfort
- Check the standard rim F against your wheel; 14.00R20 requires a 10.00 rim width
- Inflate to the pressure shown for your load in the size table; dual and single fitment pressures differ
- Inspect tread and sidewall after each off-road cycle for embedded stones or damage
- Rotate tyre positions before irregular wear sets in, especially on vehicles with uneven load distribution
LDM991 Buying Questions
What is the minimum order quantity?
We load by full container. A 40HQ of 14.00R20 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?
14.00R20 in 18PR and 20PR. Full load index, rim and pressure data for each is in the size table on this page.
Is this tyre suitable for off-road use?
Yes. The tyre is designed for off-road all-position use and is suitable for dump trucks, loaders, excavators and similar vehicles operating on unpaved terrain.
Can you supply ETRTO marked tyres?
Yes. The LDM991 is marked to ETRTO standard. Confirm your market requirement and we confirm the marking is available before shipment.
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.
