Tire size	Rim size and bolt pattern	Pressure, psi
255/40R18 99Y	Rim 18x8.5 ET24 ~~5x112~~	33 psi
225/45R18 95V	Rim 18x7.5 ET21 ~~5x112~~	33 psi
235/40R19 96V	Rim 19x8 ET29 ~~5x112~~	33 psi
255/35R19 96Y	Rim 19x9 ET29 ~~5x112~~	36 psi

How to read 99Y: 99 is the load index (up to 1,709 lb / 775 kg per tire) and Y the speed rating (up to 186 mph / 300 km/h). ET24 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.
Thread size: Lug bolt or nut thread — needed when buying aftermarket fasteners.
