What LSM401(L-4S) Is Built For
LSM401(L-4S) is a bias OTR tyre designed for loaders operating in underground tunnels under seriously tough service conditions. The flat and smooth tread pattern reduces the risk of punctures from stone, while the construction delivers excellent wear and cut resistance. It is available in two ply ratings, 14 and 16, for the 10.00-20 size, with a tread depth of 35.0 mm and a rim width of 7.5. The tyre is built for heavy-duty mining and tunnel work where surface debris and sharp rock are common.
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 puncture resistance to stone in underground tunnel environments
- Excellent wear and cut resistance for prolonged service in harsh underground conditions

- Tread depth of 35.0 mm provides long casing life under heavy-duty off-road use
- Rim width of 7.5 matches standard loader wheel configurations in underground mining equipment
Problems It Solves
- Tyres failing early due to cuts and punctures from sharp rock in underground tunnel environments
- Frequent tyre replacements caused by poor wear resistance in high-abrasion underground conditions
- Inadequate puncture resistance from tread patterns with deep grooves that trap stone
- Mismatch between tyre ply rating and actual load in underground loader applications
- Lack of a dedicated OTR tyre pattern for loaders operating in confined, high-impact underground spaces
Who It Is For
- Mining contractors sourcing tyres for underground loader fleets
- Tunnel construction companies buying tyres for tunnel access and support vehicles
- Fleet operators managing loaders in underground mining or tunnel projects
- Distributors supplying OTR tyres for underground mining and tunnel applications
- Government or infrastructure projects requiring OTR tyres for tunnel maintenance equipment
Application Scenarios
- Loaders operating in underground tunnels with high levels of rock debris and sharp aggregate
- Mining support vehicles working in confined, poorly lit tunnel environments with frequent impacts
- Tunnel construction fleets requiring consistent tyre performance without frequent replacements
- Heavy-duty loader operations in quarries with underground access points and rough haul roads
- Fleets needing a single OTR tyre pattern that resists cuts and wear in continuous underground duty
Technical Features
- Bias casing construction suitable for underground loader service conditions
- Flat and smooth tread pattern designed to reduce stone entrapment and improve puncture resistance
- 35.0 mm tread depth across both ply ratings for extended casing life
- 10.00-20 size with 7.5 rim width standard for loader wheel compatibility
- Available in 14 and 16 ply ratings to match loader axle load requirements

From Size List to Loaded Container
Confirm the 10.00-20 size, ply rating, and load index against the loader's axle load 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
- Markings such as DOT or ECE 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 General-purpose OTR tyres with deep lug patterns
The flat and smooth tread of LSM401(L-4S) resists stone entrapment better, but a deep lug pattern may offer more traction in soft ground
Compared With Radial OTR tyres for underground use
Bias construction provides better cut resistance in sharp debris environments, though radial tyres may offer longer tread life on smooth surfaces
Compared With Tyres with higher load index but lower ply rating
The 14 and 16 ply ratings in this model match the load capacity for the 10.00-20 size; overspecifying ply rating does not increase load capacity beyond the table
Use Guide
- Match the ply rating to the actual axle load of the loader, not to the maximum available
- Check the rim width (7.5) against the wheel on your loader before ordering
- Inflate to the pressure shown in the size table for the specific ply rating and load
- Inspect the tread surface after each shift in underground tunnels for embedded stone or cuts
- Rotate tyres before uneven wear sets in, especially on loaders with one-way duty cycles
LSM401(L-4S) Buying Questions
What is the minimum order quantity?
We load by full container. A 40HQ of 10.00-20 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?
10.00-20 in 14 and 16 ply ratings. Full load index, pressure, and rim data for each is in the size table on this page.
Is this tyre suitable for underground tunnel use?
Yes. It is specifically designed for loaders operating under seriously tough service conditions in tunnels, with excellent wear and cut resistance and a flat tread to reduce punctures.
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.
