Truck & Bus Radial · Export supply
Truck and bus radials,
by the container.
TBR supply for importers, distributors and fleets — one pattern per axle position, 20" tube-type through 24.5" tubeless, and the full specification published for every size we list.
01 Start with the axle
Five jobs. Five different tyres.
A steer tyre and a trailer tyre fail for opposite reasons. Pick the position first and the pattern follows.
02 The range
Six patterns, no overlap.
Each one exists because a position demands something the others cannot do — tread depth, tread width, ply rating or rim diameter.
Steer / All Position
D601
Five-rib highway pattern. The widest size and load coverage in the range.

D603

Drive

04 How we supply
Built for people who buy by the container.
Rockland Tire is a supply brand. We put our name on TBR production, publish the full specification for every size we list, and keep those sizes available long enough for a distributor to build a programme around them.
- One casing, several ply ratings
- D601 runs 14PR to 20PR on the same tread — one SKU family covering two load classes.
- Both worlds of rim
- 22.5" and 24.5" tubeless for modern fleets; 20" tube-type where that is still the standard.
- Numbers you can put in a quote
- Inflation and load are published for single and dual fitment on every line.
