Why so many wheel studs?
Why so many wheel studs?
(OP)
What is the driving force in the increase number of wheel studs a car or truck has? I have seen single lug racing wheels (for speed in changing),a three lug, 4 lug, 5 lug, now the migration is to 6 lug wheels. Why ? or is this just a "fashion" trend.
Thanks

Thank you for the prompt reply. It just seemed odd to me the big Lincolns, BMW, MB, etc, having 5 lugs then the smaller 1/2 ton trucks having 6wheel lugs.

Luck is a difficult thing to verify and therefore should be tested often. - Me

On subsequent race cars, bigger, heavier, more powerful, an improperly tightened wheel would end up pulling over the nuts but, never breaking a stud. I have broken studs, for sure, but only from over torquing them.
I'm not convinced about the "spreading the shear" theory, as the Roger Penske Trans Am team of AMC Javalins used only FOUR studs---At least until the SCCA made them go back to five. They never had a failure.

Evidence in favour of this is that the driven wheels are subject to frequent torque reversals yet the wheel/hub interface shows no sign of scuffing. If there is no relative motion between the two then no shear can be generated in the studs.
