About truck & bus tires
Truck and bus tires are a cost-per-kilometer business. Fleets evaluate tires by tread life, retreadability, fuel efficiency, damage resistance and downtime, not purchase price alone. Operating conditions such as regional haul, long haul, construction and quarry, or urban bus service determine the right product.
Construction
- TBR (truck and bus radial) – all-steel radial construction; dominant in most markets for long haul and regional transport.
- TBB (truck and bus bias) – nylon bias construction; still used in some markets for heavily loaded trucks on rough roads, tipper operations and where repair and price are priorities.
Sizes
- Tubeless: 11R22.5, 12R22.5, 13R22.5, 295/80R22.5, 315/80R22.5, 385/65R22.5 (trailer and steer), 215/75R17.5 and 235/75R17.5.
- Tube-type: 8.25R16, 8.25R20, 9.00R20, 10.00R20, 11.00R20, 12.00R20 and bias equivalents, used with tubes and flaps.
Positions and patterns
- Steer – rib patterns for precise handling and even wear.
- Drive – lug or block patterns for traction.
- Trailer – rib patterns focused on low rolling resistance and scrub resistance.
- All-position and mixed service – for on/off-road use, with cut- and chip-resistant compounds.
Specifications
Load index for single and dual fitment, speed symbol, ply rating, tread depth, and retreadability. Retreading is widely practiced, so casing quality is part of product value.
Applications
Medium trucks such as the Hino 500 commonly use 22.5-inch tubeless or 20-inch tube-type fitments depending on market, while heavy trucks and buses use larger sizes. See the truck parts section for related components.
Buying & specification guide
- Size, load indexes (single/dual), speed symbol and ply rating.
- Construction and type: TBR or TBB; TL or TT with tubes and flaps as required.
- Position and pattern: steer, drive, trailer or all-position; application such as long haul, regional, mixed service or urban bus.
- Compound: cut- and chip-resistant compounds for construction, mining and unpaved routes.
- Retreadability: ask for casing construction information if fleets retread.
- Certification and date codes for the destination market.
- Container loading: truck tires are heavy and bulky; loading quantities are far lower than light-vehicle tires. Request loading plans and securing methods.
- Fleet trials: run pattern trials on representative routes and record cost per kilometer before volume commitments.
- Claims: agree procedures for inspecting failed tires, since overload, underinflation and mechanical issues cause most failures.
- Mixed sizes: fleets often need steer and drive patterns in the same size; order both positions in proportion to axle configuration.
Export supply
Truck & Bus Tires can be quoted on FOB, CFR, CIF, FCA or EXW terms and combined with other product groups in a single consolidated container. Send part numbers, quantities and destination port for a validated quotation.
Frequently asked questions
Is TBR always better than TBB?
Radial truck tires usually deliver lower cost per kilometer through longer tread life and better fuel efficiency. Bias tires remain competitive in severe overloading, rough roads and markets where purchase price and simple repairs dominate.
What does 11R22.5 mean?
A tire approximately 11 inches in section width, radial construction, fitted to a 22.5-inch rim. It is a common tubeless truck size in many markets.
Can truck tires be retreaded?
Yes. Retreading is standard practice for many fleets. Casing condition, construction and prior operating conditions determine how many times a tire can be retreaded.
