Tire size	Rim size and bolt pattern	Pressure, psi
Front255/45R19 100H	Rim 19x8 ET32 ~~6x127~~	30 psi
Rear295/40R20 106H	Rim 20x10 ET14 ~~6x127~~	30 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). ET32 is the wheel offset: how far the mounting face sits from the rim centre, in millimetres. Compare offsets in the wheel offset calculator.

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.
Staggered: A wider tire on the rear axle than the front. Front-to-back rotation is not possible.
Thread size: Lug bolt or nut thread — needed when buying aftermarket fasteners.
