One badly judged kerb and you've got a cracked hubcap or a snapped clip. Before buying a whole new set, let's look at what's genuinely worth repairing.
What can be repaired
One or two broken clips. Universal replacement clips exist and fit cold. As long as the hubcap's outer ring is intact, the repair holds perfectly well.
A short crack, away from the edge. Plastic welding — or a reinforcing strip bonded on the back — stops it spreading. It isn't pretty from behind, but it doesn't show once fitted.
A surface scratch. On a plain hubcap, plastic polish helps a lot. On a printed hubcap, don't polish: you'd attack the print.
What can't be repaired
A crack on the outer rim. That's the area taking all the clipping load. Repaired, it relaxes and the hubcap eventually flies off — often on a dual carriageway.
A hubcap warped by heat or buckled. It will never regain its seating plane.
More than three broken clips. By then the ring has usually flexed all the way round; it's wasted effort.
The real calculation
It isn't only about money. A hubcap repaired in the wrong place is a hubcap you lose again, and one lost on the road is a hazard to others. On the clipping area, replace without hesitating.
Repair the original, or start a fresh set
An original hubcap replaced on its own never quite matches the other three: faded colour, dulled plastic, discontinued part number. That is where the call gets made — repair it, or move to a complete, matching set.
Before fitting the new one
Check the rim edge. The impact that broke the hubcap may have distorted the wheel — and a distorted edge will break the next one too. Then work through the fitting steps in order.
You can order a set of 4 hubcaps, in your own design, in the exact size of your wheels.
Repair or replace: the three cases
It all depends on how it broke, and the answer is more clear-cut than people expect.
One broken clip, everything else intact. The most common case, and the only one that genuinely repairs. A hubcap holds on several bearing points spread around its circumference; enough usually remain to keep the part on. But a hubcap held by weakened points eventually leaves while you drive — and it always leaves at the worst moment.
A crack across the disc. The plastic takes temperature swings, road spray and constant vibration. A crack doesn't settle: it travels. Epoxy holds for a few weeks, rarely more.
A kerb strike. Here the part is usually distorted as well as split, and it will never recover its geometry. No repair holds on a warped hubcap, because the bearing points no longer line up with the wheel.
Why almost nobody repairs them
The arithmetic is quick. The time spent bonding, sanding and repainting far exceeds what the part is worth, and the result shows. More to the point, a repaired hubcap stays a weakened part on something that rotates permanently.
So the real question isn't «repair or replace» but «replace one, or all four».
One or all four?
Replacing a single one costs less today, and it shows on the road. A new hubcap next to three bleached by the sun is a wheel that jars. Plastic fades and dulls; the gap becomes visible within months.
That is why hubcaps have traditionally been sold in sets of four. At Rim Crew a full set runs €79.90 to €129.90 depending on size, from 12 to 17 inch — often the price of two genuine parts bought separately at a dealer.
Avoiding the next one
Breakage almost always has an identifiable cause, and two of them are avoidable.
The wrong size. Too small and it never seats properly; too large and it strains its clips. The size is on the tyre sidewall, not on the car model.
Refitting after a garage visit. Many losses happen in the days following a tyre change: the hubcap went back on in a hurry and one clip was never engaged. Check them yourself before driving off.
Kerbs. That one is only solved at the wheel.
Frequently asked
Can you glue a cracked hubcap?
Technically yes, durably no. The plastic works constantly under vibration and heat, and the crack comes back.
Do you need the exact original part number?
No. What matters is the size in inches and compatibility with a steel wheel, not the vehicle brand.
How do I know if a hubcap is still sound?
Take it off and inspect the clips at the back. If they are whitened, deformed or brittle to the touch, the part is finished even when the front looks perfect.
Is a missing hubcap a problem at inspection?
No, a hubcap is not an inspection point. It is a matter of looks and protection, not compliance.
