LB03SD(L-5)
- 5 sizes
- Radial OTR
LB03SD(L-5) is a radial OTR tyre designed specifically for loaders operating in harsh, high-impact environments such as quarries, mining sites, and construction yards. The tyre features a substantial crown and reinforced shoulders with a protection band, built to resist shock ruptures, cuts, and tread tearing. A resilient casing with multiple steel belts enhances resistance to punctures.
What LB03SD(L-5) Is Built For
LB03SD(L-5) is a radial OTR tyre designed specifically for loaders operating in harsh, high-impact environments such as quarries, mining sites, and construction yards. The tyre features a substantial crown and reinforced shoulders with a protection band, built to resist shock ruptures, cuts, and tread tearing. A resilient casing with multiple steel belts enhances resistance to punctures. The wide, aggressive tread pattern delivers a balanced performance between adhesion, traction, and durability under heavy load and rough terrain conditions. Five sizes are available from 17.5R25 to 29.5R25, covering loader models with varying axle loads and rim widths.
Manufacturer Feature Claims
- Exceptionally robust in masacre conditions A substantial crown, robust shoulders reinforced with a protection band make up a tyre particularly resistant to shock ruptures, cuts and tread tearing. A particularly resilient casing with the addition of several specific steel belts constitute a tyre that is very resistant to punctures
- Excellent compromise of adhesion and traction A very substantial, wide and aggressive tread functions perfectly to produce a good compromise between adhesion,traction and damage resistance
Key Benefits
- Reinforced shoulders with protection band resist cuts and tread tearing in high-impact environments
- Multiple steel belts in the casing improve resistance to punctures and casing failure
- Wide, aggressive tread pattern balances adhesion, traction, and damage resistance
- Substantial crown design reduces risk of shock ruptures from rock impacts and debris
- Load capacity up to 22,400 kg at 600 kPa on the 29.5R25 size for heavy-duty loader applications
Problems It Solves
- Standard OTR tyres fail prematurely due to shoulder cuts and tread tearing on rocky surfaces
- Punctures from sharp debris lead to frequent casing replacements and downtime
- Lack of consistent traction and durability across mixed terrain reduces loader productivity
- Multiple tyre patterns required for different loader types increase inventory and fitting complexity
- Casing failure from shock ruptures reduces retreadability and increases total cost of ownership
Who It Is For
- Mining and quarry contractors sourcing tyres for loader fleets in high-abrasion environments
- Construction companies replacing tyres that fail due to cuts, punctures, or shoulder damage
- Fleet managers seeking a single OTR pattern that performs across multiple loader models
- Importers and distributors supplying OTR tyres to markets where loader durability is a priority
- Government or infrastructure projects requiring tyres for heavy-duty loader operations in rugged terrain
Application Scenarios
- Loaders in open-pit quarries handling large rock and aggregate loads over uneven, sharp terrain
- Mining site loaders moving material across graded haul roads with frequent rock impacts
- Construction yard loaders transporting heavy materials on unsealed, debris-strewn surfaces
- Fleets operating loaders in mixed-duty environments where both traction and casing durability are critical
- Operators needing a single tyre pattern that resists damage from sharp edges, stones, and repeated impacts
Technical Features
- Radial OTR construction with reinforced shoulders and protection band for impact resistance
- Multiple steel belts in the casing to resist punctures and casing failure
- Wide, aggressive tread pattern designed for balanced adhesion and traction under load
- Substantial crown height to reduce risk of shock ruptures from rock and debris impacts
- Tread depth of 475 mm across all sizes, ensuring long service life under heavy-duty use

Where This Pattern Wins and Where It Does Not
Compared With Standard OTR tyres without reinforced shoulders
LB03SD(L-5) resists shoulder cuts and tread tearing better in rocky, high-impact environments
Compared With Deep-lug off-road tyres for mining trucks
LB03SD(L-5) offers better balance between traction and casing durability on loader-specific duty
Compared With Tyres without multiple steel belts
The additional steel belts in LB03SD(L-5) improve puncture resistance and casing life
Use Guide
- Match ply rating and load index to your actual loader axle load and rim width
- Inflate to 600 kPa at both 50 km/h and 10 km/h speed ratings as specified in the size table
- Inspect tread and shoulder areas after each shift for embedded debris or early signs of damage
- Rotate tyre positions before uneven wear sets in, especially on loaders with one-sided loading patterns
- Use the 475 mm tread depth as a reference for retread timing and casing life management
LB03SD(L-5) Buying Questions
What is the minimum order quantity?
We load by full container. A 40HQ of LB03SD(L-5) typically fills 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 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?
17.5R25, 20.5R25, 23.5R25, 26.5R25, and 29.5R25. Full load index, rim, pressure, and capacity data for each 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 each size before order placement.
What warranty do you give?
One year against manufacturing defect on all tyres we supply, with claims handled directly by us. 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 loaders only?
Yes. This tyre is designed specifically for loaders. Do not use it on other vehicle types such as mining trucks or forklifts.
