They are so common now, much cheaper to get a set used. However it is somewhat pricey to buy the longer wheel studs required for the thicker aluminum. There are many places that polish used wheels, making them look like new.
Pros and cons to both wheel types.There are "go-no go" gauges for wheels. The fastener contact on stud pilot are capable of wearing. Get 'em from the manufacturer.Used wheels are used for a reason... busnut needs to be very careful checking for cracks and the above wear. Who dumps a good wheel???Aluminium rims don't bend when you whack 'em hard into a curb/etc, they crack/shatter... steel will bend...Major fleets to this day go either way, aluminium or steel, each for really good reasons.School yourself up, pick yer poison?Happy coaching!Buswarrior
