Tire size	Rim size and bolt pattern	Pressure, psi
185/65R15 92H	Rim 15x6 ET49 ~~4x100~~	30 psi
175/70R14 88T	Rim 14x5.5 ET49 ~~4x100~~	30 psi
195/55R16 91H	Rim 16x6 ET49 ~~4x100~~	30 psi

How to read 92H: 92 is the load index (up to 1,389 lb / 630 kg per tire) and H the speed rating (up to 130 mph / 210 km/h). ET49 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.
