The cost to repair a cracked alloy wheel will depend on many factors.
As the crack is usually caused by impact damage, there may also be a buckle which will also need repairing.
If the split is on the inside of the wheel, after the repair has been done & the crack is welded, as it's in an area which is not seen, it may not need fully refinishing.
On the other hand, if the crack is on the front face, then after the alloy welding is done, the wheel will need to be refurbished or re-painted to make the repait invisible.
Because of all of these potential circumstances, the cost to repair the wheel can vary widely, so it's best to contact us directly & we can assess what's required to carry out the repair, but in 99% of the cases, it will be a far lower cost than that of a genuine replacement wheel.
