Alloy wheel protection starts before the first gritting, not after.
In France, winter road maintenance services spread an average of between 300,000 and 500,000 tonnes of de-icing salt every winter. This salt deposits directly onto alloy wheel rim edges — areas that are unpainted on the vast majority of light alloy wheels. The result: galvanic corrosion that begins within the first few weeks of cold weather and eats deep into the metal before a single kerb strike has had the chance to finish the job. Autumn, when switching to winter tyres, is the logical window for fitting alloy wheel protectors — not in spring, when the damage is already done.
What salt does to an alloy wheel in just a few weeks
Sodium chloride does not attack steel: it attacks aluminium and its alloys through electrochemical corrosion. On a new alloy wheel, the flank of the rim edge (the "lip") is often machined or simply lacquered — sometimes left untreated altogether. As soon as the surface layer is micro-scratched — by a kerb scrape, a stone chip, or a slightly rough tyre fitting — the bare aluminium is exposed.
Under typical winter conditions:
- A matter of days is enough for salt to accumulate in the micro-cracks of the lacquer
- 3 to 6 weeks of driving on salted roads causes the first white spots to appear (aluminium oxidation)
- A full winter can cause sufficient corrosion to render polishing or straightening ineffective without a full restoration
Added to this is the snowdrift effect: kerb edges disappear beneath compacted snow. The driver can no longer see the kerb, making a scrape inevitable. The alloy wheel takes an impact it would never have sustained in normal conditions, directly on the rim edge — the most vulnerable area.
Why switching to winter tyres is the right moment
Changing tyres requires the wheel to be removed. This is precisely when fitting an alloy wheel protector is simplest and most cost-effective: the tyre is already separated from the alloy wheel, and the rim edge is accessible without any additional handling. Adding a set of AlloyGators during this appointment requires no extra time off the road for the vehicle.
Outside of this window, fitting remains possible in around one hour at a network approved fitter, with the wheels already mounted — but the autumn timing remains the most sensible option. Waiting until spring means leaving an entire winter's worth of salt damage and kerb strikes hidden by snow to occur on unprotected rim edges.
What it costs, in concrete figures
| Scenario | Estimated cost |
|---|---|
| AlloyGator set (4 protectors) + network fitting | approximately €99 |
| Polishing an oxidised alloy wheel (per wheel) | €40 to €80 / wheel |
| Full restoration of a corroded and buckled alloy wheel | €150 to €300 / wheel |
| Original alloy wheel replacement (part + fitting) | €300 to €800 depending on the model |
A set fitted in October covers all four wheels for less than the cost of restoring a single damaged alloy wheel. For vehicles fitted with large alloy wheels (18 to 20 inches), replacement costs are consistently at the top of the range.
How to go about it this autumn
If your vehicle requires a switch to winter tyres, the approach is straightforward: book an appointment with an AlloyGator network approved fitter at the same time as your tyre specialist, or ask the approved fitter to combine both operations if they offer both services. Owners of BMW alloy wheels, for Audi alloy wheels or for Ford alloy wheels will find on the website the exact reference of the profile suited to their rim diameter and width. The online colour simulator allows you to select the colour of the alloy wheel protector before ordering, to match the bodywork or rim colour.
FAQ
Can alloy wheel protectors be fitted in winter if winter tyres are already mounted?
Yes. Fitting onto mounted wheels is possible and takes approximately one hour at a network approved fitter. Cold temperatures do not affect fitting quality, but installation in a heated workshop is preferable for handling the profile under better conditions.
Are the protectors resistant to de-icing salt and anti-freeze products?
The AlloyGator profile is manufactured from high-resistance nylon. It is unaffected by chlorides (road salt), chemical de-icers and gravel spray. It acts as a physical barrier between these corrosive agents and the aluminium rim edge.
Do the protectors need to be removed when switching back to summer tyres?
No. The set is designed to remain in place all year round, regardless of the type of tyre fitted. The profile stays firmly attached to the rim during tyre fitting and removal operations carried out by a suitably equipped professional.
