Tire size	Rim size and bolt pattern	Pressure, psi
255/40R20 101Y	Rim 20x8.5 ET43 ~~5x112~~	–
245/45R19 102V	Rim 19x8 ET39 ~~5x112~~	–
255/35R21 98Y	Rim 21x8.5 ET43 ~~5x112~~	–

How to read 101Y: 101 is the load index (up to 1,819 lb / 825 kg per tire) and Y the speed rating (up to 186 mph / 300 km/h). ET43 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.
