Tire size	Rim size and bolt pattern	Pressure, psi
175/65R15 84S	Rim 15x5 ET45 ~~4x100~~	35 psi
175/60R16 84S	Rim 16x5 ET45 ~~4x100~~	35 psi
195/55R16 84S	Rim 16x6 ET41 ~~4x100~~	33 psi
205/45R17 84S	Rim 17x6.5 ET38 ~~4x100~~	30 psi

How to read 84S: 84 is the load index (up to 1,102 lb / 500 kg per tire) and S the speed rating (up to 112 mph / 180 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.
