Fitting alloy wheels is one of the most visually transformative upgrades available for the MGB and one of the most popular modifications in the ownership community. The standard MGB steel wheel runs a 4 to 5-inch rim, the Roadster on 4Jx14, the GT on 5Jx14, both painted in the silver-grey colour called Aluminium (BMC paint code AL.1). The alloy wheels in the MGOC Spares range are predominantly 5.5 inches wide, increasing the tyre contact patch for a more planted feel on the road without requiring any modification to the wheel arches. Both 14-inch and 15-inch diameter options are available across a range of finishes, giving owners the choice of period-correct or contemporary styling to suit the character of the individual car.
Five sub-categories cover the full alloy wheel offering. Minator Sport alloys and Hi-Lite alloys provide the classic Mini-Lite inspired spoke design that has defined the modified MGB look for decades and remains as visually effective today as when it first appeared on competition cars. Dunlop-style alloy wheels offer an alternative multi-spoke design for owners wanting a different aesthetic. Centre lock alloys are available for cars with wire wheel hubs, allowing the upgrade to alloy rims without changing the hub specification, a significant advantage for owners who want the practical and maintenance benefits of alloy wheels while retaining the wire wheel hub arrangement.
MGB Limited Edition alloy wheels cover the five-spoke LE specification fitted to 1979 and 1980 Limited Edition cars, which require specific wheel nuts and differ from the standard alloy range.
