I purchased a set of MB rims from a 2002 500s and the lug bolts were 14mm by 2.67" long. My existing bolts are 12mm by 2.00" long.

I will buy 12mm by 2.60" long and here is my question about nstalling them.
Does the lug bolt keeps the wheel by compressing the rim with the conical shape or does the 12mm bolt has to have a bushing to make it more tight into the whole. The 14mm bolta from the 500 s did not fit tight into the rim but obviously tighter than the 12mm that I need to install.

Hope you guys understand my unclear question.
