How to read 88H: 88 is the load index (up to 1,235 lb / 560 kg per tire) and H the speed rating (up to 130 mph / 210 km/h). ET22 is the wheel offset: how far the mounting face sits from the rim centre, in millimetres. Compare offsets in the wheel offset calculator.

What these columns mean
Rim size
Rim diameter × width in inches, and the factory offset (ET) in millimetres, e.g. 18x7.5 ET25.
Bolt pattern (PCD)
Number of studs and the diameter of the circle they sit on. It must match exactly.
Center bore
Diameter of the hub hole. Larger aftermarket bores need hub-centric rings.
Pressure
Recommended cold inflation pressure for that axle, in psi.
Thread size
Lug bolt or nut thread — needed when buying aftermarket fasteners.
