12R22.5 tyres for container prime movers: choosing the right tread pattern by axle

Why do container prime movers use 12R22.5?

Container prime movers cover long distances with high axle loads and need tyres with low rolling resistance to cut fuel cost and to reach high mileage. The 12R22.5 on a 22.5-inch tubeless rim meets all three requirements: a radial casing that stays stable at high speed, a one-piece rim that reduces weight and leakage, and a wide size range that allows the correct tread pattern to be selected for each axle.

Short answer: choose 12R22.5 18PR with load index 152/149; rib pattern on the steer axle, lug or block pattern on the drive axle, low-rolling-resistance rib pattern on the trailer.

Choosing tread patterns by axle position

Each axle on a prime mover does a different job, so the tread patterns differ too. Using the wrong pattern on one axle makes those tyres wear markedly faster than the others.

The table below gathers every 12R22.5 variant in the catalogue, with load index and tread depth, for quick matching against the vehicle in service.

Checks before ordering 12R22.5 tyres

1. Correct 22.5-inch rim: do not interchange with 11.00R20 (20-inch rim) or 12.00R20.
2. Correct load index 152/149: equivalent to 3,550 kg per tyre in single fitment and 3,250 kg in dual fitment. Check the actual axle load.
3. Correct packaging type: 12R22.5 is a tubeless tyre and does not use a tube or flap.
4. Correct route: on North – South asphalt routes choose a rib pattern; on routes with site sections choose a mixed pattern.
5. Correct inflation pressure: see truck tyre pressure and the load table for each variant.

12R22.5 and 315/80R22.5: which size to choose?

Both sizes share a 22.5-inch rim but use different measurement systems: 12R22.5 specifies width in inches, while 315/80R22.5 is metric with a 315 mm width and an 80% aspect ratio. Both reach comparable load indices at their highest ply rating, but 315/80R22.5 is typically used on European prime movers and large buses, whereas 12R22.5 is more common in Asian container fleets.

The real cost of a 12R22.5 tyre

For a prime mover covering 100,000 – 150,000 km a year, tyre cost per km depends mainly on the mileage a tyre achieves rather than on the purchase price. The full calculation is in truck tyre prices and real cost per km.

Frequently asked questions

How many kg can a 12R22.5 carry?

With load index 152/149 at 18PR ply rating: 3,550 kg per tyre in single fitment and 3,250 kg in dual fitment, at the pressure given in the load table for that variant.

Does 12R22.5 use a tube?

No. It is a tubeless tyre fitted to a sealed one-piece 22.5-inch rim.

Should the drive axle use a rib pattern?

Not if the road is frequently slippery. A rib pattern on the drive axle reduces traction and increases wheel spin.

Can tyres be rotated between axles?

Rotate only between positions with the same tread requirement. Moving a steer-axle tyre to the drive axle makes it wear faster and lose grip.
