Why crack welding is almost always cheaper than a new wheel
Big-rim premium cars take the worst of it. A 20-inch Range Rover Vogue alloy, a 19-inch BMW M Sport, a 21-inch Audi RS6 wheel. Main dealer replacements are eye-watering. A properly welded and refurbished wheel from our Slough workshop is a fraction of that and looks identical once the lacquer goes back on.
If it's pothole damage on the M4, the A4 through Colnbrook, or a kerb in a Windsor car park, the answer is almost always the same: bring it in, let our welders look at it, get a proper opinion before you spend on a replacement.
Forged supercar rims are worth saving too. A cracked Ferrari 488 forged wheel, a split Lamborghini Huracán rim or a Bentley Continental 22 with a hairline by the bead can usually be TIG welded back to spec rather than replaced at main dealer prices. Bring it in and we'll have a proper look before you commit to a new rim.
How we do it
- Strip and inspect. Tyre off, wheel cleaned right back to bare alloy, crack mapped under a strong light.
- TIG weld with the right filler. Different alloy grades need different rods. We don't guess.
- Re-machine or re-profile. So the bead seat is true and the rim flange is right.
- Pressure test. The wheel sits at pressure before we agree it's sound.
- Refurb the face. Diamond cut, full colour change or factory finish, whatever yours had.
- Balance and refit. Road Force balance so there's no steering wheel shudder afterwards.
What we won't weld
Some damage isn't safe to repair. A crack running clean across a spoke. A wheel that's been bent and re-bent more than once. Cracks with internal porosity right through the casting. If your alloy falls into that bracket, the team at Onyx Autocentre will tell you and recommend a replacement. We'd rather lose a job than send a customer out on a wheel we don't trust.
Drivers from Slough, Langley, Maidenhead and Gerrards Cross trust us with their cracked alloys every week. Five minutes from M4 J5, six from M25 J14.
