- Label, marking, and packaging adjusted to the destination market requirement
Where This Pattern Wins and Where It Does Not
Compared With Radial truck tyres in the same load range
Bias construction provides a stiffer sidewall and higher load capacity at lower cost, but may have higher rolling resistance and shorter highway mileage
Compared With Other bias tyres with lower ply ratings
LL178 offers higher ply ratings and load indices, suitable for heavier payloads and longer service cycles
Compared With Tyres with lower tread depth
LL178 has deeper tread across all sizes, supporting longer wear life under heavy-duty use
Use Guide
- Match ply rating and load index to your actual axle load, not to the maximum available
- Check the rim width listed in the size table against your wheel: 5.50F for 6.50-16LT and 7.00-16LT, 6.00G for 7.50-16LT, 6.0 for 7.50-20, 6.50H for 8.25-16LT, 6.5 for 8.25-20
- Inflate to the pressure shown in the size table for your load and size combination
- Monitor tread wear and replace before the tread depth reaches 2 mm to avoid casing damage
- Inspect for sidewall damage after heavy loading or off-road use, as bias tyres are less tolerant of impact
LL178 Buying Questions
What is the minimum order quantity?
We load by full container. A 40HQ of LL178 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?
6.50-16LT, 7.00-16LT, 7.50-16LT, 7.50-20, 8.25-16LT, and 8.25-20. Full load index, rim, pressure, and dimensions for each are in the size table.
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.
Is this tyre suitable for buses?
Yes. LL178 is designed for both truck and bus applications, with load indices and ply ratings suitable for heavy-duty bus service.
