Tire size	Rim size and bolt pattern	Pressure, psi
265/75R16 116S	Rim 16x7.5 ET38 ~~6x139.7~~	30 psi

265/65R18 114S	Rim 18x8 ET38 ~~6x139.7~~	35 psi

How to read 116S: 116 is the load index (up to 2,756 lb / 1,250 kg per tire) and S the speed rating (up to 112 mph / 180 km/h). ET38 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.
