Tire size	Rim size and bolt pattern	Pressure, psi
165/50R16 75V	Rim 16x4.5 ET45 4x100	35 psi
165/50R15 75V	Rim 15x5 ET40 4x100	30 psi
185/45R15 75V	Rim 15x6 ET38 4x100	30 psi

How to read 75V: 75 is the load index (up to 853 lb / 387 kg per tire) and V the speed rating (up to 149 mph / 240 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.
