Tire size	Rim size and bolt pattern	Pressure, psi
185/60R15 85T	Rim 15x5.5 ET45 ~~4x100~~	33 psi
185/55R16 85T	Rim 16x6 ET39 ~~4x100~~	33 psi

205/45R17 84H	Rim 17x7 ET30 ~~4x100~~	30 psi

How to read 85T: 85 is the load index (up to 1,135 lb / 515 kg per tire) and T the speed rating (up to 118 mph / 190 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.
