Wheel cover or alloy wheel: the choice determines what gets damaged, how much it costs to repair, and how you can protect your investment.
When changing vehicles or buying second-hand, the question often comes up: are the wheels fitted with plastic wheel covers or genuine alloy wheels? The distinction is far from cosmetic. It affects the replacement cost in the event of an impact, resistance to kerbing, and the precautions needed in everyday driving.
Wheel cover or alloy wheel: what exactly are we talking about?
A hub cap is a plastic cover — sometimes ABS, sometimes polypropylene — clipped onto a standard steel wheel. It conceals the wheel for aesthetic purposes. An alloy wheel (aluminium or magnesium) is the wheel itself: it is cast or forged, with no cover fitted over it.
- Wheel cover on steel wheel: fitted as standard on entry-level trim levels. The wheel cover can be replaced on its own (£10 to £50 per unit depending on the model), but the steel wheel underneath remains exposed to corrosion if the cover comes off.
- Alloy wheel: fitted on mid-range to high-end trim levels. Replacement cost: £80 to £400 per unit new, depending on diameter and brand, excluding fitting and balancing.
- Wheel cover for alloy wheel: a rarer category — a decorative cap fitted over an existing alloy wheel. Sometimes used to give a uniform appearance to an axle set or to conceal a partial repair.
Steel or alloy wheel: what gets damaged most, and why
Steel wheels are resilient against frontal impacts (potholes, kerbs), but they tend to bend rather than crack — and they rust as soon as the surface coating is damaged. Plastic hub caps, on the other hand, crack or come off entirely at the first brush against a kerb.
Alloy wheels handle light lateral pressure better, but they are far more susceptible to kerb scrapes: polished or painted aluminium scratches easily, and the rim edge crumples against low obstacles. A superficial scratch on an alloy costs £40 to £90 per wheel to repair (sanding, painting, lacquering) at a specialist bodyshop. A deeper impact requires rebuilding or full replacement.
| Wheel type | Main weak point | Indicative repair cost |
|---|---|---|
| Steel wheel + wheel cover | Lost hub cap, rusted wheel | £10 – £50 (wheel cover only) |
| Standard alloy wheel | Scrape or crushing of the rim edge | £40 – £90 per wheel (repair) |
| Large-diameter alloy wheel (19–22 inches) | Low-profile tyre sidewall, exposed rim edge | €80 – €400 depending on depth and panel |
Large-diameter wheels are particularly vulnerable: the thinner tyre sidewall absorbs less of the lateral impact. The alloy rim edge rubs directly against the kerb. If your vehicle is fitted with 18-inch wheels or larger — particularly on Audi models or BMW, where these sizes are common from mid-range trim levels onwards — the risk of kerbing damage when parking is considerably higher.
Can an alloy wheel be protected in the same way as a hub cap?
No. A lost hub cap can be replaced for under €50. A kerbed alloy wheel incurs significantly higher repair or replacement costs, and the damage accumulates quietly with every tight parking manoeuvre.
That's exactly what AlloyGator alloy wheel protectors are designed for: a polymer profile fitted between the tyre and the wheel rim, compatible with wheels from 12 to 24 inches, TÜV approved and MIRA tested. The complete set (4 protectors, available in 15 colours) is priced at €134.90 inc. VAT. Fitting is carried out by a certified approved fitter from our network, with the vehicle raised and the tyre deflated, in 45 minutes to 1 hour — from €99 depending on the fitter, with a quote available before your appointment. Fitting is not included in the price of the set.
For Ford or Dacia vehicles, which are often delivered with steel wheels and wheel covers, the question is slightly different: AlloyGator is fitted to the steel wheel itself, not to the plastic cover.
FAQ
Can a hub cap be fitted over an AlloyGator protector on an alloy wheel?
No. AlloyGator is fitted to the rim edge, between the tyre sidewall and the alloy. Fitting a decorative wheel cover on top would alter the clamping and could interfere with the fixing. The two accessories are not designed to be used together.
Steel or alloy wheel: which is more expensive to maintain in the long run?
Steel wheels are cheaper to replace, but plastic hub caps deteriorate quickly (UV exposure, impacts) and need to be changed regularly. Alloy wheels last longer when protected from kerbing damage, but each repair is more costly. On a city vehicle, the difference in maintenance costs tends to even out over 3 to 5 years.
Does AlloyGator work on both steel and alloy wheels?
Yes, the profile is compatible with both types, for diameters ranging from 12 to 24 inches. The fitting process is identical in both cases: vehicle raised, tyre deflated, carried out by a certified approved fitter in approximately 45 minutes to 1 hour.
