By Torque, AIWheelTech vehicle & fitment specialist · 1991–present

Vauxhall Astra-G wheel fitment in one line: The Vauxhall Astra-G Caravan (1991–present) uses a 5x110 bolt pattern, 65.1 mm centre bore, M12x1.5 bolts torqued to ~110 Nm. It accepts ~6J–8.5J wheels at ET25–ET49.

Overview

The Vauxhall Astra-G Caravan is part of the second generation Opel/Vauxhall Astra series, produced from 1998 to 2004. It was available as a five-door estate (station wagon) known in Europe as the 'Caravan' and later renamed to Sports Tourer. This model succeeded the first-generation Astra F Caravan and featured significant improvements over its predecessor, including enhanced chassis tuning by Lotus Engineering which also formed the basis for the Opel Zafira MPV.

History & notable variants

The Astra G series was launched in 1998 with a range of body styles including coupé and cabriolet variants introduced later. It received a facelift in 2003, updating its design and adding new features such as natural gas-powered engines. The model continued production until the introduction of the Astra H series.

Everything below is what the fit-check uses for Vauxhall Astra-G wheel fitment: the factory bolt spec first, then the width and offset window that clears the arches and the brakes on the Vauxhall Astra-G Caravan.

Aftermarket wheel sizes — read per position:

Go wider and the offset has to rise with it, about 8 to 10 ET per extra 1J, or the wheel pokes past the arch. The fit-check settles the exact offset and any spacer.
