Wheel nuts sheared off

I fitted mazda 123 wheels to my hyundai excel 1994 5 dr hatch. The stud
pattern seemed to be exact and the car has probably done 4000kms. No
problems, perfect balance until last night my wife turned the corner at the
end of our street and 3 wheel studs sheared of with a clean break( no
corrosion ). I've wheel braced enough tyres on in my time so I don't
overtighten.

Maybe the rim wasn't fitting flush against the hub.

Any ideas?

 

How do the center holes in the wheels fit the hubs? If they're too
small, wheels won't contact the hub. If they're too large, the studs
must bear all the weight of the car and acceleration and braking stresses.

 

thank some one she wassnt hurt

Since found out that the hyundai rims have a depression for the bolts
attaching the brake disks whereas the mazda rims don't.

Traps for young players eh!
