LSM402
- 19 sizes
- Bias OTR
LSM402 is a bias OTR tyre designed for underground mining and tunnel work where the surface is uneven, rocky, and subject to high abrasion and impact. The wide tread arc and deep pattern are built to extend casing life under continuous heavy load and sharp rock contact.
What LSM402 Is Built For
LSM402 is a bias OTR tyre designed for underground mining and tunnel work where the surface is uneven, rocky, and subject to high abrasion and impact. The wide tread arc and deep pattern are built to extend casing life under continuous heavy load and sharp rock contact. The sole sidewall protection design resists punctures from sharp debris and edge strikes common in confined underground environments. It is available in 19 sizes across 9 ply ratings, from 9.00-20 to 18.00-25, with load capacities up to 18,000 kg. The tyre is not intended for on-road or highway use.

Where This Pattern Wins and Where It Does Not
Compared With Standard OTR tyres without sidewall protection
The sole sidewall protection design in LSM402 reduces puncture risk in rocky underground environments where edge strikes are frequent
Compared With OTR tyres with shallow tread patterns
The deep pattern and wide tread arc in LSM402 extend casing life under continuous heavy load and abrasive conditions
Compared With On-road or highway bias tyres
LSM402 is not designed for paved surfaces; using it on roads reduces tread life and increases rolling resistance
Use Guide
- Match ply rating to actual axle load, not to the highest available rating, to avoid over-specification and unnecessary cost
- Check rim width against the wheel: 7.0 for 9.00-20, 7.5 for 10.00-20, 8.5 for 12.00-20 and 12.00-24, 10.0 for 14.00-24, 14.00/1.5 for 17.5-25, 13.00/2.5 for 18.00-25
- Inflate to the pressure shown in the size table for your load; dual and single fitment pressures differ
- Inspect sidewalls after each underground cycle for signs of impact or puncture damage
- Rotate tyres before irregular wear sets in, especially on fleets with uneven load distribution
LSM402 Buying Questions
What is the minimum order quantity?
We load by full container. A 40HQ of LSM402 typically fills by weight rather than volume, so the practical minimum is one container. Mixed loads across sizes and ply ratings 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 and ply ratings are available?
19 sizes from 9.00-20 to 18.00-25, with ply ratings from 14 to 44. Full load, pressure, and rim data for each size is in the size table.
Is this tyre suitable for on-road use?
No. LSM402 is designed for underground work only. It is not intended for paved or highway use.
Can you supply DOT or ECE marked tyres?
Marking requirements vary by destination. Tell us your import market and we confirm what markings the plant can supply on that 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 OTR patterns?
Yes. Most of our customers load one container across several OTR patterns and sizes, which is the main reason to buy through us rather than from a single plant.
