Tire size	Rim size and bolt pattern	Pressure, psi
235/55R18 99V	Rim 18x7.5 ET45 ~~5x114.3~~	33 psi
235/50R19 97V	Rim 19x8 ET50 ~~5x114.3~~	33 psi
245/45R20 99W	Rim 20x8 ET50 ~~5x114.3~~	36 psi

How to read 99V: 99 is the load index (up to 1,709 lb / 775 kg per tire) and V the speed rating (up to 149 mph / 240 km/h). ET45 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.
