Steel disc wheels and Rostyle wheels both benefit from stainless trims that lift their visual character without the cost of a complete wheel change. The early cars up to the late 1960s left the factory on plain steel disc wheels with a separate polished hub cap covering the centre stud, both functional in covering and protecting the wheel-nut hardware and decorative in carrying the MG badge or octagon as a styling element, while the later cars on Rostyle wheels can be dressed with polished stainless face trims. This section gathers the modern stainless and chromed reproductions of the original hub caps, the period-style trim rings used to dress up steel wheels, and the polished stainless Rostyle face trims, all manufactured from stainless steel that will not pit, rust, or lose its finish like older chromed mild steel did over time.
Hub Caps in the Original Patterns
The chrome-bumper cars up to the late 1960s used a flat polished chrome-or-stainless hub cap with the MG octagon on the centre face, the same pattern used on the earlier MGA with the appropriate octagon style for the period. Hub caps are reproduced in stainless steel, durable and presenting an authentic period appearance without the pitting that affected older chromed mild-steel items, fitting the standard wheel-nut arrangement on the original disc-wheel applications by pushing on over the wheel nuts and held in place by the spring action of the cap itself. Removal for wheel-nut access is straightforward, a screwdriver or hub-cap removal tool levering the cap off without damage, and where the original hub caps have deteriorated beyond restoration the modern stainless reproductions are typically the cost-effective renewal, appearance comparable to new chrome with the long-term durability that the original plating cannot match.
Rostyle Face Trims & Rim Trim Rings
Polished stainless steel Rostyle face trims fit over the face of a Rostyle wheel, covering it with a polished stainless disc that provides a completely different visual appearance from the standard Rostyle finish, the trim clipping over the Rostyle face and secured by the existing wheel nuts, sitting flush with the rim edge for a clean integrated look. These trims have the practical benefit of covering a Rostyle wheel that is in poor cosmetic condition, providing an immediate visual improvement without the time and effort of a full wheel renovation, and they are equally effective on freshly renovated wheels where the polished stainless edge provides a crisp contrast to the wheel face. Trim rings are the polished stainless or chrome rings that fit around the outer edge of a steel wheel, dressing up the appearance without changing the wheel itself, covering the bare outer rim and giving a polished bright outer edge that bare steel cannot achieve, a period dealer-fit accessory in the late 1960s and 1970s that remains a popular cost-effective alternative to alloy or Rostyle conversion. Trims and rings fit the standard wheel diameters used across the range, typically 14-inch for most MGB applications, 13-inch for the Midget and earlier applications, and 15-inch for the MGC.
Fitting & Care
Hub caps, trim rings, and face trims are straightforward to fit, no tools typically needed beyond a flat-bladed screwdriver for prying a hub cap into the right position, the trim rings spring-fitting around the rim and staying in place under driving, and the face trims secured by spring tension against the rim bead or by the wheel nuts, fitted or removed by hand without drilling or modification. When fitting the face trims, the trim should be centred on the wheel before the wheel nuts are tightened, as an off-centre trim will be visible as an uneven gap around the rim edge. Care is straightforward, periodic cleaning with a mild detergent, occasional polishing with a stainless-steel polish to maintain the bright finish, and inspection for kerb damage that could distort a trim ring out of round, with the stainless finish being maintenance-free compared with chrome which requires regular polishing to prevent tarnishing, retaining its bright appearance indefinitely with only occasional washing. The trims add a small amount of weight to each wheel, but this is negligible in practice, and they offer a reversible way to refresh the look of the car's wheels while protecting the wheel face underneath.
