Virtually any wheel can be changed to another colour, be it gloss black, satin titanium, shadow chrome, or colour coded to your car.
Are usually only one colour and can be any colour. Usually they are silver, black, or titanium. They can be gloss, satin, or matte finish.
When a wheel has a collision, usually with a pothole but could be with a curb, another car, etc. it can get bent out of round.
Lots of wheels we repair require the tyres to be removed and then refitted and precision stud balanced.
