Tire size	Rim size and bolt pattern	Pressure, psi
Front255/35R20 93Y	Rim 20x9 ET22 ~~5x120~~	–
Rear285/30R20 99Y	Rim 20x10 ET20 ~~5x120~~	–

How to read 93Y: 93 is the load index (up to 1,433 lb / 650 kg per tire) and Y the speed rating (up to 186 mph / 300 km/h). ET22 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.
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.
