Tire size	Rim size and bolt pattern	Pressure, psi
185/60R14 82H	Rim 14x5.5 ET45 4x100	30 psi
185/55R15 82V	Rim 15x6 ET45 4x100	33 psi
195/45R16 85V	Rim 16x6.5 ET45 4x100	33 psi

How to read 82H: 82 is the load index (up to 1,047 lb / 475 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.
