Tire size	Rim size and bolt pattern	Pressure, psi
275/65R18 116T	Rim 18x8.5 ET44 ~~6x135~~	35 psi
275/55R20 113T	Rim 20x8.5 ET44 ~~6x135~~	35 psi
285/45R22 114H	Rim 22x9.5 ET44 ~~6x135~~	38 psi

How to read 116T: 116 is the load index (up to 2,756 lb / 1,250 kg per tire) and T the speed rating (up to 118 mph / 190 km/h). ET44 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.
