Tire size	Rim size and bolt pattern	Pressure, psi
205/60R16 92V	Rim 16x6.5 ET41 ~~5x115~~	35 psi
225/50R17 94V	Rim 17x7 ET44 ~~5x115~~	35 psi

How to read 92V: 92 is the load index (up to 1,389 lb / 630 kg per tire) and V the speed rating (up to 149 mph / 240 km/h). ET41 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.
