Tire size	Rim size and bolt pattern	Pressure, psi
245/70R17 110T	Rim 17x7 ET25.4 5x139.7	44 psi

How to read 110T: 110 is the load index (up to 2,337 lb / 1,060 kg per tire) and T the speed rating (up to 118 mph / 190 km/h). ET25.4 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.
