What is Alloy wheels?
[[File:Geneva MotorShow 2013 - Aston Martin DB9 wheel.jpg|thumbnail|Alloy wheels on a [[car]]]] '''Alloy wheels''' are automobile [[wheel]]s that are made of an [[aluminum alloy]] instead of [[steel]]. Most new cars have alloy wheels, either as standard equipment or as an option. Older buses and large trucks almost never have alloy wheels, but they have recently become an option on newer models. The first alloy wheels were made of [[magnesium]] alloys, but these are no longer made because the magnesium alloys were too weak and would eventually crack. [[Category:Auto parts]] {{tech-stub}}
