Tire size	Rim size and bolt pattern	Pressure, psi
235/55R18 100H	Rim 18x8 ET37 ~~5x120~~	33 psi
245/45R20 99H	Rim 20x8.5 ET37 ~~5x120~~	33 psi

245/50R19 101H	Rim 19x8 ET37 ~~5x120~~	33 psi

How to read 100H: 100 is the load index (up to 1,764 lb / 800 kg per tire) and H the speed rating (up to 130 mph / 210 km/h). ET37 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.
