What the AI looks for in Heavy Duty Vehicle Tires, Wheels & Hubs
- Size chain match
- Tire size, rim diameter and rim width must match: 11R22.5 and 295/75R22.5 run on 22.5x8.25 wheels; wide-base 445/50R22.5 and 455/55R22.5 need 22.5x14 wheels A tire on the wrong rim width or diameter cannot seat or carry its rated load.
- Mounting system
- Modern Class 8 trucks are hub-piloted, 10 studs on a 285.75 mm (11.25 in) bolt circle; older trucks may be stud-piloted with ball-seat nuts Hub-piloted and stud-piloted wheels, nuts and hubs do not interchange.
- Load capacity per axle
- Tire load range, wheel load capacity and hub capacity must each meet or exceed the axle's gross axle weight rating The weakest component sets the safe load for the whole wheel end.
- Wheel position
- Choose steer, drive or trailer parts for the position they will run in Tread design and wheel offset are engineered for a specific axle.
Brands that matter
- Michelin: Wide line-haul and regional tire range with strong casings for retreading.
- Bridgestone: Major fleet tire supplier, with Bandag retreading in the same group.
- Goodyear: Full commercial tire lineup with a national truck service network.
- Alcoa (Howmet): Benchmark forged aluminum truck wheels.
- Accuride: Large maker of steel and aluminum commercial wheels.
- ConMet: Major supplier of heavy-duty hubs, including preset bearing hubs.
What to avoid
- Mixing hub-piloted and stud-piloted wheels, nuts or hubs
- Running mismatched tire diameters in a dual set
- Buying a tire or wheel without confirming the axle load it must carry
Questions
Can I replace dual tires with a single wide-base tire?
Yes, but you need wide-base wheels with the correct outset, and you must check that the axle and hub are approved for that offset.
