Well I was putting on my winters, and while torquing the bolts SNAP, one of the breaks in half. I have never thought this could happen but somehow it has. What would I need to replace in this case.

As well, I will assume it is unsafe to drive with 4/5 lug nuts, since this is my DD? Any suggestions?

 

fix it before you use it.

 

well was it rear wheel? or front wheel?.. if its rear wheel you have to take your hub out to change your stud and for s2000 if you take your hub bearing out you have to put new one for rear.

and its ok to drive 4/5 lugs 4 lugs gonna hold enought to use DD
but gotta go fix it ASAP

 

front wheel

 

wheels stud(pressed in stud, not a screw/bolt like a VW/bmw) breaks quite often, mostly from wear and tear and over torquing.

you might able to get away from having it press out if it's only the front.

 

So what toque are the setting them to? Or is it a jump up and down on the wrench to make sure it's on there?

Since it's a front, you should be able to remove the hub and press in a new stud. Assuming Honda sells just the stud.

It will be OK to drive. Don't take the corners hard and overstress the rest of the studs though.
