Alloy Wheel Damage: Repair or Replace
Alloy wheels are damaged easily and repaired routinely. The distinction that matters is between cosmetic damage to the surface and structural damage to the wheel itself.
Cosmetic damage
Kerbing marks on the rim edge and face are the most common. Specialists refurbish these by machining or filling the damaged area, refinishing and lacquering.
Mobile services handle a single wheel at modest cost in a couple of hours. Full refurbishment of a set at a workshop costs more per wheel and produces a better and more durable finish, since the wheel is removed, stripped and refinished properly.
Diamond-cut finishes, where the face is machined to a bright finish under lacquer, are more expensive to repair because they require a lathe. Painted finishes are cheaper.
Structural damage
Cracks, usually from potholes or impacts, are a different matter. Welding a cracked alloy is possible and contested — a repair on the inner rim may be acceptable, while cracks in the spokes or across the face generally are not.
Buckling from impact can sometimes be straightened by a specialist, and severe buckling weakens the metal.
The safety consideration is real: a wheel failure at speed is serious. Where there is any doubt, replacement is the correct decision.
Reputable repairers will decline structural repairs they consider unsafe, which is itself a good sign.
Diagnosing a problem
Vibration at speed frequently indicates a buckled wheel rather than a balancing issue, particularly if it appeared suddenly after an impact.
A tyre that loses pressure slowly may be sealing poorly against a damaged rim rather than being punctured.
Have the wheel checked on a balancer, which shows runout and identifies buckling.
Replacement options
Genuine manufacturer wheels are the most expensive and guarantee fit and finish.
Aftermarket wheels vary in quality. Check load rating, offset, centre bore and PCD, since a wheel that physically fits may still be wrong for the vehicle.
Used genuine wheels from breakers are frequently good value and should be inspected for the same damage you are trying to resolve.
Insurance may cover damage from a pothole under accidental damage, though the excess frequently exceeds the repair cost.
Practical points
Repair before selling. The cost of refurbishing a set is usually recovered several times over in the price and the impression the car makes.
Check whether refurbishment affects the tyre — many processes require removal and refitting, and it is a sensible moment to check tyre condition.
If damage recurs regularly, consider whether the wheel and tyre combination is the cause. Large wheels with very low-profile tyres offer little protection against kerbs and potholes, and replacing them at the next opportunity solves the problem permanently.
