Lug bolts for winter wheels
I purchased for a decent price a set of used X3(E83) rims. I'm about to purchase Blizzaks from TireRack and also may need lug bolts. I've read postings that indicate that I should use M14x1.25 spherical seat 17mm heads
As I've researched many questions keep popping up and I need some help!
1) Does a conical head = spherical head= radius head?
2) What thread lenght/shank length do I need to order? Is this rim dependant?
3)Should I use existing lugs bolts for both summer and winter rims?
3) I've seen geniune BMW bolts with rotating washers - but everything else appears to have the one piece bolt. Any recommendation?
Thanks
