Tire size	Rim size and bolt pattern	Pressure, psi
175/70R13 78S	Rim 13x5.5 ET41 ~~4x108~~	29 psi

How to read 78S: 78 is the load index (up to 937 lb / 425 kg per tire) and S the speed rating (up to 112 mph / 180 km/h). ET41 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.
