Tire size	Rim size and bolt pattern	Pressure, psi
245/70R17 119R	Rim 17x7.5 ET57 ~~8x165.1~~	75 psi
275/70R18 125R	Rim 18x8 ET43 ~~8x165.1~~	59 psi
285/60R20 125R	Rim 20x8 ET54.65 ~~8x165.1~~	65 psi

How to read 119R: 119 is the load index (up to 2,998 lb / 1,360 kg per tire) and R the speed rating (up to 106 mph / 170 km/h). ET57 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.
