Tire size	Rim size and bolt pattern	Pressure, psi
185/70R14 88H	Rim 14x5.5 ET45 4x98	26 psi

195/55R16 87H	Rim 16x6 ET45 4x98	29 psi

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. 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.
