I purchased a 94' S500 about 6 months and with it came the stock rims (in the trunk) and shiney new rims on the car. Last evening we hit a pot-hole, blowing the front-right tire. Oops -- It was dark. Come to find out, the lug bolts on the new tires are too short for the spare tire and stock rims forcing me to hire a tow-truck.

Does anyone know the size of lug bolts the stock tires take? I want to be for sure since it's a safety issue. Tires coming off at 65 mph. may give me a heart attack.

 

43mm from the end to the beginning of the taper

 

Perfect. Thanks.
