Tire size	Rim size and bolt pattern	Pressure, psi

225/75R16	Rim 16x6.5 ET125 ~~8x165.1~~	65 psi

How to read 112Q: 112 is the load index (up to 2,469 lb / 1,120 kg per tire) and Q the speed rating (up to 99 mph / 160 km/h). ET125 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.
