Winter road conditions in London expose alloys to salt, slush and spray — a perfect recipe for corrosion.
London’s winter gritting leaves salt residue that creeps under damaged lacquer and corrodes alloys. Prevent it by getting kerb damage refurbished before winter, adding ceramic or sealant protection, regular pH-neutral washes, proper drying — and book refurbishment promptly if lacquer starts to lift.
Rock salt (mainly sodium chloride) helps keep roads passable — but when mixed with water and oxygen it creates a conductive electrolyte that accelerates corrosion. Aluminium alloys don’t rust like steel; instead, they oxidise beneath the protective lacquer. A chip, kerb rash or hairline crack lets saltwater in; the lacquer blisters, paint lifts, and pitting spreads under the finish.
White, chalky deposits; dulling despite washing; rough texture on rim edges.
Bubbling/peeling lacquer; visible pitting around valve holes, wheel bolts and the bead seat.
Slow air leaks, poor balance and long-term finish failure.
London’s winters are wet and mild — ideal for constant damp roads. Local councils grit priority routes throughout the season — you can check which roads your council grits on GOV.UK — and the salty film and slush linger, and stop–start traffic throws residue onto inner barrels and behind spokes. Add urban kerbing and brake dust and you’ve got a perfect corrosion cocktail.
Once corrosion is creeping under the lacquer, washing won’t reverse it. Our technicians strip back the failed coating, neutralise corrosion and refinish the wheel (e.g., powder coating or diamond cutting) to restore appearance and, crucially, protection. If the bead seat is affected, refurbishment also resolves slow leaks and improves safety.
Corrosion that stops a tyre sealing at the bead is a genuine roadworthiness concern — wheel and tyre condition is assessed under the DVSA MOT inspection manual (axles, wheels, tyres and suspension), so it is worth putting right rather than living with.
They oxidise instead; the result is lacquer lift and pitting.
It rinses surfaces but leaves residue in barrels and behind spokes.
Corrosion spreads under the finish; act early.
If you notice bubbling/peeling lacquer, visible pitting or slow air loss, get the wheel assessed promptly. Early intervention is usually far less costly than replacement and prevents deeper structural issues — see our wheel repair prices for guidance before you book.
