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). ET45 is the wheel offset: how far the mounting face sits from the rim centre, in millimetres.

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.
