Re: Why does Mercedes use bolts instead of nuts for the wheels?
Using bolts instead of studs makes it very easy to change from one wheel style to another, without rquiring the wheel manufacturer to machine recesses to get down to the right engagement depth for studs.<br> My C-class came with a steel wheel spare (albeit full size). The spare wheel kit has a different set of wheel mounting bolts, shorter than the standard bolts used to attach stock alloy wheels, to match the thinner steel wheel.<br> The down side is that on a stud-equipped car, ruin a stud or nut and you're only out a couple bucks and a couple minutes either way. If some idiot with an impact wrench ruins the threads on a Mercedes wheel hub, you'll spend several dollars putting in a thread insert, or substantial money replacing the hub.
